Notes XT1...XT4 A) The presence of an auxiliary supply is required for the local bus and zone selectivity functions (see Fig. 51-81). B) The undervoltage coil is provided for power supply branched on the supply side of the circuit-breaker or from an independent source: circuit-breaker can only close when coil is ener- gized (closing lock is obtained mechanically). C) Contacts 84/1 and 84/2 of Fig. 7-8 open circuit when circuit-breaker is open and close it again when a manual closing command is imparted by means of the rotary handle, in accordance with the Standards governing machine tools (however, circuit-breaker will not close if under- voltage release is not being supplied). E) If the application in Fig. 21 and the contacts in Fig. 31 must be installed at the same time, con- tact 0/2 must be installed in the adjacent slot (marked 0/1). F) R= Additional external undervoltage resistor supplied at 380/440 VAC and 480/525 VAC. R1= Additional external resistor for stored en- ergy motor operator or direct action motor op- erator supplied at 480/525VAC. 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 Tl/N transformer must be short-circuited when the circuit-breaker must be removed. H) "Galvanically separated converters" conforming to standards IEC 60950 (UL 1950) or equivalent must be used since an earthed Uaux is required. I) Mandatory in the presence of any sort of Ekip module. L) Only one application among Fig. 83...97-131-132 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. 83...97-131-132, 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, at least one mod- ule 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 S75l/5 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- breakers" for connection of the EIA RS485 se- rial 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 1SDCOO741ZGO201 "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. 51 or 81 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.
