The following is a key to the notes used in the wiring diagrams:
Note
Description
A)
The auxiliary power supply for the Ekip release is obligatory
C)
Always supplied with the Ekip Com module.
D)
Always supplied with the motor for loading the closing springs (diagram 13)
E)
Voltage transformer, mandatory in the case of external outlet sockets.
External outlet sockets, mandatory for systems with rated voltage greater
than 690V.
F)
The connections between the residual-current protection RC sensor and
the poles of connector X (or XV) of the circuit-breaker must be implemented
with a screened two-pole cable with paired braided conductors (BELDEN
9696 paired type or equivalent), with length no greater than 10m. The
screen must be earthed on the circuit-breaker side.
