13.13 Standby supply board
option
The standby supply board option provides the possibility of
keeping the communication system up and running without
having the 3-phase mains connected. One advantage is that
the system can be set up without mains power. The option
will also give backup for communication failure if main
power is lost.
The standby supply board option is supplied with external
±10% 24 V
DC
protected by a 2 A slow acting fuse, from a
double isolated transformer. The terminals X1:1, X1:2 (on
size B, C and E to F) are voltage polarity independent.
The terminals A- and B+ (on sizes D/D2...) are voltage
polarity dependent.
Cable length limited to 30 m. If the cable is longer than
30 m, a shielded cable must be used.
