— Reading information Circuit breakers
Notes A) Auxiliary supply for Ekip trip unit is mandatory ( refer to diagram 1SDM00009R0001 figures 31 - 32- 33 - 34). B) When there are mixed auxiliary contacts Q1 and Q2 are 400V, while Q3 and Q4 are 24V. Then Q5, Q6, Q7 are 400V, while Q8, Q9, Q10 are 24V. C) Always supplied with Ekip Com module. D) Always supplied with motor for loading closing springs in Fig. 13. E) Obligatory voltage transformer in the case of external sockets. Obligatory external sockets for systems with rated voltage greater than 690V. F) The connections between the RC residual cur- rent protection sensor and the poles of the X connector (or XV) of the circuitbreaker must be made with 4-pole shielded cable with conductors interwoven in pairs (type BELDEN
K) Only for E2.2, E4.2 and E6.2 withdrawable version circuit-breakers as an alternative to Fig. 31-32-33. K) Only for E2.2, E4.2 and E6.2 withdrawable version circuit-breakers as an alternative to Fig. 31-32-33. L) In the presence of Fig. 32, for E2.2, E4.2 and E6.2 circuit-breakers up to three applications be- tween Fig. 41…58 taken only once can be sup- plied, instead for E1.2 circuit-breakers, up to two applications between Fig. 41…58 taken only once can be supplied. The Ekip Com module selected can be duplicated if required, by choosing between Fig. 61…66. M) In the presence of Fig. 33, for E2.2, E4.2 and E6.2 circuit-breakers, up to two applications be- tween Fig. 41…58 taken only once can be sup- plied. The Ekip Com module selected can be du- plicated if required, by choosing between Fig. 61…66. N) In the presence of Fig. 34, for E2.2, E4.2 and E6.2
9696 paired or equivalent), of a length no greater than 10 m. The shield should be grounded on circuit-breaker side.
circuit-breakers, a single application between Fig. 41…58 can be supplied.
G) With all electronic protection trip units equipped with display interface with LSIG protections, protection against a ground fault is available (Gext) by means of current sensor positioned on the star center of the MV/LV
O) In the presence of several Ekip Com modules with withdrawable version circuit-breakers, the contact S75I/5 should be connected only once to a single module. P) The auxiliary voltage Uaux. enables activation of all the functions of the EKIP electronic protection trip units. Since an earth insulated Uaux was requested, it is necessary to use “gal- vanically separated convertors” which comply with the standards IEC 60950 (UL 1950) or equivalent, which provide a com- mon mode current or leakage current (refer to IEC 478/1, CEI 22/3) no greater than 3.5mA, IEC 60364-41 and CEI 64-8. Q) Regarding local bus the maximum cable lenght is 15m. R) Suggested RJ45 cable: CAT6 STP. T) Connect terminals 120 Ω on to insert a termina - tion resistance on the Local Bus.
transformer. The connection between terminals 1 and 2 of the UI/O current
transformer and Ge+ and Ge- poles of the X con- nector (or XV) must be made with shielded and stranded 2-pole cable (type BELDEN 9841 or equivalent) of length no greater than 15 m. H) The connection between the terminal box and external neutral sensor must be made with the 2m cable provided. For three pole circuit- break- ers, the Ne+ and Ne- poles of the X connector (or XV) must be short-circuited if no sensor is present on the external neutral con- ductor. I) Obligatory in the case of the presence of any Ekip module. J) Only for E2.2, E4.2 and E6.2 withdrawable version circuit-breakers as an alternative to Fig. 31-32-34.
