M) Opening and closing commands from Ekip Ac- tuator can be obtained with Y0 and Y0 coils, with 110-120VDC and 240-250VAC maximum voltage values. N) Use BELDEN 3105A cables or equivalent. O) Contact 8751/5 should be connected once only to a single module when there are several Ekip Com modules with withdrawable cir- cuit-breakers. P) Auxiliary voltage Uaux. Enables all the func- tions of the EKIP electronic protection releases to be activated. "Galvanically sepa- rated convertors" conforming to standard IEC 60950 (UL 1950) or equivalent must be used since an earthed Uaux is required. Q) Use BELDEN 3105A cables or equivalent not more than 15m in length. R) Recommended RJ45 cable: CAT6 STP. S) Consult "Technical Application Papers - vol. 9: Bus Communication with ABB Circuit-breakers" for serial line connection EIA RS485. T) Short-circuit terminals 1200 on if a terminating resistor must be connected to the Local Bus. U) Use Belden 3079A cables or equivalent. For fur- ther details see White Paper 1SDCOO741200201 "Communication with SACE Emax 2 Circuit- Breakers". V) Use Belden 3084A cables or equivalent. For fur- ther details see White Paper 18DCOO7412G0201 "Communication with SACE Emax 2 Circuit- Breakers". W) Contacts S4/1 and S4/2 in Fig. 17 can be used to open the undervoltage coil circuit shown in Fig. 73-74 when the circuit-breaker is open and to close it again in the presence of a closing command, in compliance with the Standard governing machine tools.
X) Contact S52 signals the state of the Y02 / YU opening coils. For coil Y02, the contact connected to poles 25-28 of connector X (or XV) is closed with Y02 energized (circuit-breaker opening activated), contact 25-26 is closed with Y02 de- energized. For coil YU, the contact connected to poles 25- 28 of connector X (or XV) is closed with YU de-energized (circuit-breaker opening acti- vated), contact 25-26 is closed with YU ener- gized. Z) Ekip Supply cannot be used for direct supply to the electronic release by means of terminals K1 and K2. AA) See Fig. 31 and 32 for connection of W3 and W4. AB) Use BELDEN 8762/8722 two-pole shielded ca- ble or equivalent. The shield must be earthed on the selectivity input side (for zone selectiv- ity) or on both sides (for other applications). AC) Admissible maximum rated secondary voltage is 120V. AD) Use PENTRONIC TEC/SlTW-24F (type TX) insu- lated cables for thermocouples or equivalent, no more than I’m in length. AE) Use appropriate cables compatible with the workplace in which the 4-20mA current sensor is used and not more than 3 m in length.
