The automatic affectation is the following: from "C" to "P" slot : SWX20x, AIU201 AIU210, DOU200, AOU200, free slots if any, CCU200, DIU210, DIU200 ,TMU200 The preferred affectation of the I/O modules will be defined separately with the "CUSTOMISATION" datasheet. This manufacturing process induce extra costs. You are strongly advised to contact the marketing department to calculate the associated extra cost.

1)

Different racks exist depending of user-selected CT/VT(TMU) & basic case size : For 40T case with TMU200 (Measurement CT/VT): CAS242 (Available slots: N=4) - For 40T case with TMU210 (Protection CT/VT): CAS242 (Available slots: N=3). For 40T case without any TMUxxx (CT/VT) : CAS241 (Available slots: N=6). For 80T case with TMU200 (Measurement CT/VT): CAS282 (Available slots: N=14) - For 80T case with TMU210 (Protection CT/VT): CAS282 (Available slots: N=13). For 80T case without any TMUxxx (CT/VT): CAS281 (Available slots: N=15).

2)

Module slot size

3)

The sum of slots (S) to receive modules must not exceed the maximum value N (available slots), indicated for each case separately

4)

Output relays (2-pole) for switchgear operation

5)

Required for Synchrocheck, disturbance recorder and direct measurements

6)

According to specification

7)

Voltage regulation needs UCA2 Ethernet-based communication

8)

User-selected (factory setting underlined).

9)

With TMU200 and TMU220, the option includes the DSP200 daughter board, plugged on the CPU260 module With TMU210 the option includes the DSP210 daughter board plugged on the CPU260 module - The DSP2x0 are using Floating-Point Digital Signal Processor (DSP)

10) The sum of communication links (legacy SCADA and IEDs) must not exceed the maximum communication ports available. 11) For Specific Software version complete the Software CORTEC (sheet C264 SOFT) For C264-R multirack applications, Select " No software loaded"

12) For Detachable Front panel, define the lenght of the required cable ; the Blind panel size depend on the Rack size. for DIU210 ( Multi tension PeakCurrent board),

13) Not to be mixed with DIU200 in a same rack

Maximum nb of boards depend on the voltage level, the case size, the CT/VT presence :

14) for CPU260:only one Ethernet Port available -> exclusion of use between RJ45 copper link and optical if required in option 15) BIU100 : only in association to RPS280 (consult marketing) , Do not exist for tropicalised /Varnished version Warning : specific EMC levels for this power supply - consult Marketing before use
