J6.1
BCB_DRV
It provides a pulse signal of +24 V / 20 mA for
the remote control of the battery circuit breaker
through its shunt trip. This signal turns the
switch «Off».
J6.2
BCB_CONT
Status of the BCB switch. Its normally closed
auxiliary contact -NC- can be connected
between this pin and the GND.
J7.1
GND

5.5.7.6. Dry contacts.
Switched contacts of three relays, corresponding to three sig-
nals of the dry contacts, are supplied through terminal blocks
J8, J9 and J10. Tab. 7 shows the pinout of all of them. The
voltage and maximum current applicable to these contacts is
250 V AC 3A.
