4.2.1 Stand by supply interface
(SBS)
The control board mounted standby supply, X11 connector,
provides the possibility of keeping the communication
system up and running without having the 3-phase mains
connected. Another 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 should be supplied with a 24 VDC
±10% double isolated transformer capable of supplying 1A
continues current. Recommended fuse is 2A. Cable length
limited to 30 m. If the cable is longer than 30 m, a shielded
cable must be used.
4.3 Configuration with
jumpers and switches
4.3.1 Analogue input configuration
(S1 - S4)
The jumpers selections S1 to S4 are used to set the input
configuration for the 4 analogue inputs AnIn1, AnIn2,
AnIn3 and AnIn4 as described in table 23. See fig. 56 for the
location of the jumpers.

2 - 0 V
NOTE: In case the isolated DC measurement board
(that incorporate stand by supply [SBS] functionality)
the control-board SBS should not be used. Rather
the SBS on the isolated DC measurement board
should be used. Failure to comply with this will break
DC-link voltage measurement.
