Notes XT5-XT6 A) The presence of an auxiliary supply is required for the local bus and zone selectivity functions (see Fig. 41-78). B) The undervoltage coil is provided for power supply branched on the supply side of the cir- cuit-breaker or from an independent source: circuit-breaker can only close when coil is ener- gized (closing lock is obtained mechanically). C) Contacts S4/1 and S4/2 of Fig. 7-10-15 open cir- cuit when circuit-breaker is open and close it again when a manual closing command is im- parted by means of the rotary handle, in accor- dance with the Standards governing machine tools (however, circuit-breaker will not close if undervoltage release is not being supplied). D) Only for XT5 F-P. E) Only for XT5 G) If a three-pole fixed circuit-breaker with cur- rent transformer on the neutral conductor out- side the circuit-breaker is used, the terminals of the TI/N transformer must be short-cir- cuited when the circuit-breaker must be re- moved. H) "Galvanically separated converters" conforming to standards IEC 60950 (UL 1950) or equivalent must be used since an earthed Uaux is re- quired. I) Mandatory in the presence of any sort of Ekip module. L) Only one application among Fig. 79...93-131-132 can be supplied in the case of Ekip DIN Rail Car- tridge Basic. In the case of Ekip DIN Rail Car- tridge, up to three applications can be supplied among Fig. 79...93-131-132, taken once only. In addition, the Ekip Com module (if chosen) can be duplicated by choosing among Fig. 110...116. M) To ensure correct operation, the Ekip Supply module and at least one module must always be present. N) BELDEN 3105A cables or an equivalent type must be used. 0) When there are several Ekip Com modules with withdrawable circuit-breakers, contact 5751/2 must be connected once only to one single module.
P) Auxiliary voltage Uaux allows all the functions of EKIP electronic protection relays to be acti- vated. "Galvanically separated converters" con- forming to standards IEC 60950 (UL 1950) or equivalent must be used since an earthed Uaux is required. Q) BELDEN 3105A cables or an equivalent type must be used. Maximum length 15 m. R) Recommended RJ45 cable: CAT6 STP. S) Consult "Technical Application Papers - vol. 9: Communication via BUS with ABB circuit-break- ers" for connection of the EIA RS485 serial line. T) Short-circuit terminals 1200 on to install a ter- mination resistor on the Local Bus. U) Use Belden 3079A cables or equivalent. Consult White Paper 1SDC007412G0201 "Communica- tion with SACE Emax 2 circuit-breakers" for fur- ther details. V) Use Belden 3084A cables or equivalent. Consult White Paper 1SDC007412G0201 "Communica- tion with SACE Emax 2 circuit-breakers" for fur- ther details. Z) Ekip Supply cannot be used to energize the electronic relay via terminals K1 and K2. AA) Consult Fig. 78 for the connection of W3 and W4. AB) Use two-pole shielded cable type BELDEN 8762/8772 or equivalent. The shield must be earthed on the selectivity input side (for zone selectivity) or on both sides (for other applica- tions). AC) The rated maximum secondary voltage is 120V. AD) Use insulated cables for thermcouples such as PENTRONIC TEC/SITW-24F (Type TX) or equiv- alent. Maximum length 3 m. AE) Use suitable cables up to 3 meters in length compatible with the workplace in which the 4-20mA current sensor is used AG) Relay type TMG for XT5 only AH) Designation Connector X .. -> X3 for XT5; X4 for XT6
