*1  *1  Assuming comparatively short time storage, e.g., during ttransportation ransportation or the like. *2  *2  Even if the humidity is within within the specified requirements, avoid such places where the inverter will be subjected to sudden changes in temperature that will cause condensation or freezing. Precautions for temporary storage (1) Do not leave the inverter directly on the floor floor.. (2) If the environment does not satisfy the specified requirements listed in Table1.1 wrap the inverter in an airtight vinyl sheet or the like for storage. (3) If the inverter is to be stored in a high-humidit high-humidity y environment, put a drying agent (such as silica gel) in the airtight package described in (2) above.

[2] Long-term st orage The long-term storage method of the inverter varies largely according to the environment of the storage site. General storage methods are described below. (1) The storage site must satisfy the requirements specified for ttemporary emporary storage. However, for storage exceeding three months, the surrounding temperature range should be within the range from -10 to +30°C. This is to prevent electrolytic capacitors in the inverter from deterioration. (2) The package must be airtight to protect tthe he inverter from moisture. Add a drying agent inside the package to maintain the relative humidity inside the package within 70%. (3) If the inverter has been installed to the equipment or panel at construction sites where it may be subjected to humidity, dust or dirt, then temporarily remove the inverter and store it in the environment specified in Table1.1.

Precautions for storage over 1 year If the inverter has not been powered on for a long time, the property of the electrolytic capacitors may deteriorate. Power the inverters on once a year and keep the inverters powered on for 30 to 60 minutes. Do not connect the inverters to the load circuit (secondary side) neither run the inverter.

MOUNTING AND WIRING THE INVERTER

2. 2.1 1 Installing the Inverter (1) (1) Mounting base Install the inverter on a base made of metal or other non-flammable material. Do not mount the inverter upside down or horizontally. (2) Clearances Ensure that the minimum clearances indicated in Figure 2.1 and Table  Table  2.1 are maintained at all times. When installing the inverter in the panel of your system, take extra care with ventilation inside the panel as the ambient temperature easily rises. Do not install the inverter in a small panel with poor ventilation. When mountin g two or more inverte When inverters rs When mounting two or more inverters in the same unit or panel, basically lay them out side by side. When mounting them one above the other, be sure to separate them with a partition plate or the like so that any heat radiating from one inverter will not affect the one(s) above. Table 2.1

General

The CE marking on inverters does not ensure that the entire equipment including our CE-marked products is compliant with the EMC Directive. Therefore, CE marking for the equipment shall be the responsibility of the equipment manufacturer. For this reason, Fuji Electric’s CE mark is indicated under the condition that the product shall be used within equipment meeting all requirements for the relevant Directives. Instrumentation of such equipment shall be the responsibility of the equipment manufacturer. Generally, machinery or equipment includes not only our products but other devices as well. Manufacturers, therefore, shall design the whole system to be compliant with the relevant Directives. EMC certification testing is performed using the following wiring distances between the inverter and motor (shielded wire):   ・FRN0010LM2C-4 □ to

Re Recomm comm ended installation procedur e

To satisfy the requirements noted above, use inverters in combination with an external filter (option) dedicated to   Fuji inverters. In either case, mount inverters in accordance with the installation procedure given below. To  ensure the compliance, it is recommended that inverters be mounted in a metal panel. For details, refer to the TS-LM2C-0001-v ■-EMC filters for LM2C for EMC compliance. The document is a Technical Statement that will describe the List of filters for LM2C for fulfilling the EMC compliance. Note: ■ can be any number between 100 and 999 that means document revision. 1)

Mount the inverter and the filter on a grounded p panel anel or metal plate. Use shielded wires for the motor cable and route the cable as short as possible. Firmly clamp the shields to the metal plate to ground them. Further, connect the shielding layers electrically to the grounding terminal of the motor.

2)

For connection to inverter’s control terminals and for connection of the RS-485 communication or CAN-Bus signal cable, use shielded wires. As with the motor connections, clamp the shields firmly to a grounded panel.

3)  If noise from the inverter exceeds the permissible level, enclose the inverter and its peripherals within a metal panel as shown in Figure 8.1.

General

In FRENIC-Lift series of inverters, opening the hardware circuit between terminals [EN1]-[PLC] or between terminals [EN2]-[PLC] stops the output transistor, coasting the motor to a stop (EN: Enable input). This is the Safe Torque Torque Off (STO) compliant with Function Functional al Safety Standard EN/IEC 61800-5-2. Using the Safe Torque Off (STO) function eliminates the need of external safety circuit breakers (i.e. magnetic contactors) while conventional inverters need those breakers to set up the system compliant to Functional Safety Standard.

The output shutdown function of this this inverter uses uses the Safe Safe Torque Torque Off Off (STO) function prescribed in IEC/EN 61800-5-2 so that it does not completely shut off the power supply to the motor electrically. Depending upon applications, therefore, additional measures are necessary for safety of end-users, e nd-users, e.g., brake function that locks the machinery and motor terminal protection that prevents possible electrical hazard(s).

•

The output shutdown function does not completely shut off off the power power supply to the motor motor electrically. electrically. Before starting wiring or maintenance jobs, therefore, be sure to disconnect the input power to the inverter and wait at least five minutes.

8.6.2 8.6.2 Notes for c ompli ance to Functi onal Safety Standard Standard 1) Wiring for terminals [EN1] ((Enable Enable input 1) and [EN2] (Enable input 2) - [EN1]/[EN2] and [PLC] are terminals prepared for connection of safety related w wires; ires; therefore, careful wiring should be performed to ensure that no short-circuit(s) can occur to these terminals. - For opening and closing the hardware circuit between terminals [EN1]/[EN2] and [PLC], use safety approved components such as safety switches and safety relays that comply with EN ISO13849-1 Cat. 3 PL=e or higher to ensure a complete shutoff. -

Input cables of [EN1] and [EN2] must be segregated in different electrical conductors installed inside different conduits, otherwise the use of independent shielded cables is a must. The armor of the conduit or the shield must be connected to CM terminal.

- It is the responsibility of the machinery manufacturer to guarantee that a short-circuiting or other fault does not occur in wiring of external safety components between terminals [EN1]/[EN2] and [PLC]. Fault Examples: • Terminals [EN1]/[EN2] and [PLC] are short-circuited due to the wiring being caught in the door of the control panel so that a current continues to flow in terminal [EN1]/[EN2] although the safety component is OFF and therefore the safety function will/may NOT operate • The wiring is in contact with any other w wire ire so that a current continues to flow in terminal [EN1]/[EN2] and therefore the safety function will/may NOT operate

2) Notes for Safe T Torque orque Off (STO) function - When configuring the product safety system with this Safe Torque Torque Off (STO) function, make a risk assessment of not only the external equipment and wiring connected to terminals [EN1] and [EN2] (Enable input 1 and Enable input 2) but also the whole system including other equipment, devices and wiring against the product safety system required by the machinery manufacturer under the manufacturer's responsibility in order to confirm that the whole system conforms to the product safety system required by the machinery manufacturer. In addition, as preventive maintenance, the machinery manufacturer must perform periodical inspections to check that the product safety system properly functions. - Inverter is designed according to Pollution Degree 2 environment. If the inverter is installed inside a worse environment (for example, Pollution Degree 3 environment), the inverter may be damaged. Even though,

8-7  

 

under Pollution Degree 3 environment the safety circuit that implements the STO functional safety function will not reduce its performance. Therefore, the STO function operation can be ensured even under Pollution Degree 3. - To bring the inverter into compliance with Functional Safety Standard, it is necessary to bring it into compliance with European Standards EN61800-5-1 and EN61800-3. - This Safe Torque Off (STO) function coasts the motor to a stop.

- In case of diagnostics with a safe PLC,

short pulses with a duration less than 1 ms should be input to

terminals [EN1] and [EN2]. - The safety shutdown circuit between input terminals [EN1] and [EN2] sections and inverter's output shutdown section is a redundant circuit so that an occurrence of a single fault does not prevent the Safe Torque Off (STO) functio function. n. If a single fault is detected in the safety shutdown circuit, the inverter coasts the motor to a stop even with the terminal [EN1]-[PLC] and [EN2]-[PLC] states being ON, as well as outputting an alarm to external equipment. Note that the alarm output function is not guaranteed to all of single faults. It is compliant with EN ISO13849-1 Cat. 3 PL=e. - This Safe Torque Torque Off ((STO) STO) function may not completel completely y shut off the power supply to tthe he motor electrically. Before starting wiring or maintenance jobs, be sure to disconnect the input power to the inverter and wait at least 5 minutes.

3) Test of Safe T Torque orque Off (STO) function - [EN1]/[EN2] and [PLC] [PLC] must be turned off for diagnostics at least one time per hour hour.. Then [EN1]/[EN2] and [PLC] must be kept off for at least 2 seconds. -  Main power supply must be shut off (auxiliary power supply of the control circuit can be supplied) at least one time per one day.

Figure 8.8 shows the timing scheme to apply when EN1 and EN2 inputs are not concordant, so that an alarm ECF occurs. Turning the emergency stop button ON turns EN1 and EN2 inputs OFF, which usually brings the inverter into the Safe Torque Off (STO) state. If the discrepancy of the EN1 and EN2 inputs is within 50 ms, no alarm occurs; if it is longer than 50 ms, the inverter interprets it as a logic discrepancy, outputting the alarm ECF. The alarm can be  be cleared by restarting the inverter. To diagnose the EN terminals circuit appropriately, when turning EN1/EN2 inputs ON and OFF, keep the ON and OFF time for at least 2 s.
