Safety Precautions To reduce the chance of accident, please read the safety precautions very carefully before operation. The "Caution, Notice, Warning, Danger" in this book do not represent all the safety points to be observed, and are only supplement to various safety points. Therefore, the installation and operation personnel must be strictly trained and master the correct operations and all the safety points before actual operation. When operating Emerson products, the safety rules in the industry, the general safety points and special safety instructions specified in this book must be strictly observed.

Electrical Safety I. Hazardous voltage

Danger Some components of the power system carry hazardous voltage in operation. Direct contact or indirect contact through moist objects with these components will result in fatal injury. Safety rules in the industry must be observed when installing the power system. The installation personnel must be licensed to operate high voltage and AC power. In operation, the installation personnel are not allowed to wear conductive objects such as watches, bracelets, bangles, rings. When water or moisture is found on the Subrack, turn off the power immediately. In moist environment, precautions must be taken to keep moisture out of the power system. "Prohibit" warning label must be attached to the switches and buttons that are not permitted to operate during installation.

Danger High voltage operation may cause fire and electric shock. The connection and wiring of AC cables must be in compliance with the local rules and regulations. Only those who are licensed to operate high voltage and AC power can perform high voltage operations. II. Tools

Warning In high voltage and AC operation, special tools must be used. No common or self-carried tools should be used. III. Thunderstorm

Danger Never operate on high voltage, AC, iron tower or mast in the thunderstorm. In thunderstorms, a strong electromagnetic field will be generated in the air. Therefore the equipment should be well earthed in time to avoid damage by lightning strikes.

IV. ESD

Notice The static electricity generated by the human body will damage the static sensitive elements on PCBs, such as large-scale ICs. Before touching any plug-in board, PCB or IC chip, ESD wrist strap must be worn to prevent body static from damaging the sensitive components. The other end of the ESD wrist strap must be well earthed. V. Short circuit

Danger During operation, never short the positive and negative poles of the DC distribution unit of the system or the non-grounding pole and the earth. The power system is a constant voltage DC power equipment, short circuit will result in equipment burning and endanger human safety. Check carefully the polarity of the cable and connection terminal when performing DC live operations. As the operation space in the DC distribution unit is very tight, please carefully select the operation space. Never wear a watch, bracelet, bangle, ring, or other conductive objects during operation. Insulated tools must be used. In live operation, keep the arm muscle tense, so that when tool connection is loosened, the free movement of the human body and tool is reduced to a minimum. VI. Dangerous energy

Warning 240VA, hazardous energy, keep off, no bridge connection. This converter contains outputs exceed 240VA, when installing into end system care must be taken that the output and appropriate wire may not be touched.

Battery Danger Before any operation on battery, read carefully the safety precautions for battery transportation and the correct battery connection method. Non-standard operation on the battery will cause danger. In operation, precautions should be taken to prevent battery short circuit and overflow of electrolyte. The overflow of electrolyte will erode the metal objects and PCBs, thus causing equipment damage and short circuit of PCBs. Before any operation on battery, pay attention to the following points: Remove the watch, bracelet, bangle, ring, and other metal objects on the wrist. Use special insulated tools. Use eye protection device, and take preventive measures. Wear rubber gloves and apron to guard against electrolyte overflow. In battery transportation, the electrode of the battery should always be kept facing upward. Never put the battery upside down or slanted.

BLVD The system has battery low voltage disconnection (BLVD) function. BLVD means when the mains fail and batteries supply power, the monitoring module cuts the load off when the battery voltage drops down to below 43.2V to prevent over-discharge. The BLVD voltage is settable. Refer to 4.2.3 Battery Selection for setting method. The factory setting is enabling BLVD, which means that if power outage lasts for a long time or the power system fails, there might be BLVD. Users should classify the loads and connect the priority loads to BLVD routes. For vital loads, users can disable BLVD of these loads to insure reliability of the power supply. The method of disabling BLVD is: Set “BLVD Enable” item of the monitoring module to “N”. Refer to 4.2.3 错误！ 错误！未找到引用源。 未找到引用源。 for setting method.

Notice The advantage of enabling BLVD is protecting the batteries from over-discharge when the battery voltage is low. The disadvantage of enabling BLVD is that when the battery voltage drops down to a certain value, all the loads (including non-priority loads and priority loads) will be cut off due to battery disconnection. The advantage of software disabling BLVD is prolonging the power supply of priority loads. The disadvantage is that software disabling cannot prevent unwanted power failure due to misoperation or power system failure.

Others I. Sharp object

Warning When moving equipment by hand, protective gloves should be worn to avoid injury by sharp object.

II. Cable connection

Notice Please verify the compliance of the cable and cable label with the actual installation prior to cable connection. III. Binding the signal lines

Notice The signal lines should be bound separately from heavy current and high voltage lines, with binding interval of at least 150mm.

Check all the MCBs and cables. Are their models correct? Check the bus bar connections, input and output cable connection, and connection between the power system and the system grounding. Check the if the number and connections of the batteris are correct. Check the polarity of the battery string with a voltmeter. Make sure all the cable connections are firm and reliable.

Startup preparations Make sure that all the MCB are switched off. Measure the AC input voltage. Make sure the input voltage is within the allowable range. Check that the communication and alarm cables are connected to the signal transfer board. Check that the temperature sensor, if any, has been installed. Check that the battery string circuit is not closed. Connect the disconnected batteries to the battery string circuit Switch off unconnected battery MCBs. Check that the battery signal cables are connected to battery MCBs reliably, not loosened or suspended Measure with a voltmeter across the connection points of each battery and make sure that the polarity is right. For a lead-acid battery with 24 cells, the voltmeter should read 2.0-2.1V/cell or 48-51V/battery. If the voltage of certain cell is lower than 2.0V, that cell must be replaced. Check with an ohmmeter that there is no short circuit between the positive & negative distribution bus bars, or between the positive & negative battery poles (Note: Pull out all modules before the check and restore them after the check)

Limit: set the charging current limit. This is the maximum charging current that should be allowed into the battery at any time, as regards to the nominal capacity of the battery. For example, a value of 0.150C10 means that the charging current is limited to 15% of the battery’s nominal capacity. Over: set the over boost charging current. This is the charging current, as regards to the nominal capacity of the battery, at which an over current alarm will be initiated if this current is reached. For example, a value of 0.300C10 means that when the charging current reaches 30% of the battery’s nominal capacity, an alarm will be extended. AutoBoost: An Automatic Boost is started when one of the following conditions is reached. -Enable: Use this submenu to enable or disable auto boost charging. -Curr: This is the battery discharge current, as regards to the nominal capacity of the battery, above which an Automatic Boost is started, when the Automatic Boost function is enabled. For example, a value of 0.060C10 means that an Automatic Boost is started if the battery current is greater than 6% of the battery’s nominal capacity. -Cap: This is the remaining battery capacity under which (less than) an Automatic Boost is started when the Automatic Boost function is enabled. CycBoost -Enable: Use this submenu to enable or disable cyclic boost charging. -Period: Use this submenu to set cyclic boost charging period. This is the interval, in hours, between the boost cycles. -Time: Use this submenu to set cyclic boost charging time. This is the duration of each cycle for the Cyclic Boost when this function is enabled. Const Boost -Curr: Use this submenu to set constant boost charging current. -Time: Use this submenu to set constant boost charging time. BoostLimitTime: Use this submenu to set boost charging time limit beyond which boost charge will be stopped. Move cursor to ‘Test’, you can configure the following parameters: End Test: A Battery Test is interrupted when one of the following conditions is reached. -Volt: This is the ‘end of test voltage level’ for each battery test. -Time: This is the maximum duration, in minutes, for each battery test. -Cap: This is the remaining battery capacity, as regards to the nominal capacity of the battery, at which a Battery Test will be interrupted. For example, a value of 0.700C10 means that when the charging current reaches 70% of the battery’s nominal capacity, the battery test is interrupted. Cyc Test: Displays whether the time (on specific dates) battery test function is enabled (Y) or not (N). During a Timed Battery Test, the output voltage of the rectifiers is reduced so that the batteries power the load. If the batteries fail, the rectifiers power the load. Short Test: A short test is a short duration battery discharge test used to verify that parallel batteries are discharging equally. If the discharge current difference between the two batteries exceeds a preset level (default is 10 A), a Short Test Fault alarm is generated. -Enable: Displays whether the short (at specific intervals) battery test function is enabled (Y) or not (N). -Alarm: Displays the battery current difference at which an alarm will be extended. -Time: Displays the interval, in hours, between short battery tests. -Duration: Displays the duration, in minutes, of each short battery test. ConCurr Test: A Constant Current test is a battery discharge test done at constant current. The controller will automatically adjust the rectifiers to maintain the battery discharge current at the preset value. -Enable: Displays whether the constant current battery test function is enabled (Y) or not (N). -Current: Displays the stable test current. Move cursor to ‘TEMP COMP’, you can configure the following parameters: Center Temp: Displays the temperature, in °C, at which the syst em operates at normal voltage levels. Temp 1: Displays whether a temperature probe on MB is installed and enabled (Battery or Ambient) or not (None) in position No. 1, and if there is one, whether it is used for battery or ambient temperature measurements.

5.11 Access ACU+ Through NMS ACU+ has SNMP agent function. User can use NMS to do following operations: Query the operation status and input/output signals of the device connected to ACU+; Set the operation parameters of the device connected to ACU+; Browse the active alarms. When ACU+ generates alarms, SNMP agent can notify the preset NMS through TRAP automatically.

5.11.1 NMS Supported By SNMP Agent The SNMP agent of ACU+ supports SNMPv2c. All the NMS that supports SNMPv2c can be used to access ACU+. The NMS includes HP OpenView, IBM NetView, Novell ManageWise, SunNet Manager and so on. SNMP is a technology used for network management. The technology is based on implementing an information base called MIB (Managed Information Base). This MIB contains parameters that are interesting from a management perspective. All LAN connected equipment that support SNMP shall also support a default MIB called MIB-II. The SNMP Agent responds to requests received via the SNMP protocol and also actively sends traps to a specified manager when certain MIB values change state. This is used to actively inform a manager when an alarm situation is recognized.

5.11.2 MIB Installation MIB installation The ACU+ MIB is located in the installation CD delivered together with ACU+, and file name is acu-power.mib. Use the MIB loading function of NMS to load the MIB database, refer to the corresponding NMS user manual for the detailed loading method. Contents of MIB This MIB is suitable for the firmware version 1.10 of ACU+. The MIB will change with the upgrading of ACU+ firmware. The contents of MIB supported by ACU+ SNMP agent, and the OID are listed in Table 5-1. For the details, please refer to the file of acu-power.mib. Table 5-18

Alarm Handling

Chapter 6 Alarm Handling This chapter describes the handling of alarms, as well as the preventive maintenance of the system during system daily operation. The maintenance personnel must have adequate knowledge about the power system. Note 1. The maintenance must be conducted under the guidance of related safety regulations. 2. Only the trained personnel with adequate knowledge about the power system can maintain the inner part of the subrack.

6.1 Handling Alarms The monitoring module alarms are classified in four types: critical alarm, major alarm, observation and no alarm. Critical alarm, major alarm: these two types of alarms have strong impacts on the system performance. Whenever these alarms are generated, users are supposed to handle them immediately. The alarm indicators will be on and audible indication will be given. Observation: when this type of alarm is raised, the system maintains normal output for a while. If the alarm occurs during watch time, it should be handled immediately. If the alarm occurs during non- watch- time, handle it during watch time. The alarm indicators will be on when observation alarm occurs. No alarm: if alarms are set as ‘no alarm’ by the users, when these alarms occur, no visible or audible indication will be generated and the system works normally. The handling methods of normal alarms are given in Table 6-1. Table 6-1 System setting parameter description No.

Mains Failure

If the failure does not last long, the battery will power the load. If the cause is unknown or the failure lasts too long, a diesel generator is needed. Before using the generator power to supply the power system, it is suggested to run the generator five minutes to minimize the impact on the power system

Check if the AC over-voltage value is too low. If yes, change the value. A mild over-voltage does not affect the system operation. However, the rectifier will stop operation when the mains voltage is more than 530V. If the mains voltage is above the AC over-voltage value, the mains grid should be improved

3

AC Voltage Low

Check if the AC Under- voltage point is too high. If yes, change the value. When the mains voltage is lower than 304V, the output power of the rectifiers will be derated. And if lower than 260V, the rectifiers will stop working. If the mains voltage is under the AC under-voltage value, the mains grid should be improved

4

SPD failure

Check the SPD condition. If the SPD is damaged, replace it

DC Volt High

Check the DC over-vlotage value through the controller. If the set value is inappropriate, correct it. Otherwise, find out the rectifier that has caused the alarm: 1. Ensure that the batteries can operate normally. 2. Switch off the AC input of all rectifiers. 3. Power on the rectifiers one by one. 4. If the over-voltage protection is triggered when a certain rectifier is powered on, that rectifier is the faulty one. Replace it

6

DC Volt Low

1. Check if the alarm is caused by mains failure, if yes, disconnect some loads to prolong the operation of the whole system. 2. Check the DC under-voltage value set through the controller. If the set value is inappropriate, correct it. 3. Check if any rectifier is inoperative, or has no output current. If yes, replace it. 4. Check if the total load current exceeds the total rectifier current during float charge. If yes, disconnect some loads or add more rectifiers to make the total rectifier current bigger than 120% of the total load current with one redundant rectifier

The rectifier with the fault indicator (red) on is faulty. Power off the rectifier, and then power it on after a while. If the alarm persists, replace the rectifier

10 Rect Protect

Check if the mains voltage is above 530V or under 260V. If the mains voltage is under the AC under-voltage value or above the AC over-voltage value, the mains grid should be improved

11 Rect Fan Fails

Pull out the rectifier to check if the fan is obstructed. If yes, clean it and push the rectifier back. If the fan is not obstructed or if the fault persists after cleaning, replace the fan

12 Rect Not Respond

Check if the communication cable is connected properly between rectifier and controller. If yes, restart the rectifier. If the alarm persists, replace the rectifier

13 Batt Over Temp

1. Check if the battery compartment temperature is too high. If yes, cool down the battery compartment. 2. Check if there is battery internal fault. If yes, replace the faulty battery

Replacing rectifier fan If the rectifier fan is faulty and does not work, it should be replaced. Take the R48-1800 rectifiers as an example, the replacement procedures are as follows: 1. Use a cross screwdriver to remove the 3 screws from the fixing holes and pull out the front panel. 2. Unplug the power cable of the fan and remove the fan. Install a new fan. 3. Plug the fan power cable. Put the front panel back and fasten it with the 3 screws, as shown in Figure 6-2.

Disassembling the front panel

Replacing rectifier Except replacing the fan, it is recommended not to repair any other part of the module. When faulty, the module should be replaced, not repaired. See the following procedures to replace the rectifier. 1. Take a new rectifier and check it for any damage from transport. 2. Loosen the fixing screw of the handle of the R48-1800A rectifier with a Phillips screwdriver. Pull out the faulty rectifier from the rack by grabbing its handle. Be careful with the rectifier just pulled out from the system, as it could be very hot due to long-term operation. Do not let it slip away and get damaged. 3. By holding the rectifier handle, push the new rectifier into the slot just vacated and make sure the connection is good. After a brief delay, the rectifier run indicator will turn on and the fan will start running. 4. Check whether the new rectifier works normally. You should make sure that: 1) The monitoring module recognizes the new rectifier. 2) The new rectifier shares current with other rectifiers. 3) When this new rectifier is pulled out, there is a corresponding alarm and the monitoring module displays the alarm. If the new rectifier passes all the above tests, the replacement is a success. 5. Push the handle back into the front panel to fix the rectifier with the positioning pin. Fix the fixing screw of the handle of the R48-1800 rectifier with a Phillips screwdriver.

Over-voltage protection

The rectifier provides over-voltage hardware and software protection. The hardware protection point is 59.5V ± 0.5V, and it requires manual resetting to restore operation. The software protection point is between 56V and 59V (0.5V above output voltage, 59V by default), and can be set through the monitoring module There are two software protection modes, which can be selected through the software at the host: 1. Lock out at the first over-voltage Once the output voltage reaches protection point, the rectifier will shut off and hold that state. It requires manual resetting to restore the operation 2. Lock out at the second over-voltage When the output voltage reaches the software protection point, the rectifier will shutdown, and restart automatically after 5 seconds. If the over-voltage happens again within a set time (default: 5min. Configurable through monitoring module), the rectifier will shut off and hold that state. It requires manual resetting to restore the operation Manual resetting: Resetting can be done manually through the monitoring module, or by removing the rectifier from system
