Switches S3.7 and S3.8: number of redundant INVs
S3.7 S3.8
0 INVs
0 0
1 INV
0 1
2 INVs
1 0
3 INVs
1 1
The settings must be the same on all INVs and the SBS!
Standard setting: S3.7 and S3.8 open
Switches S3.4 and S3.5: not used
Switch S3.6: Switchover with gap (yes/no)
Standard setting: switchover not with gap - S3.6 open
i.e. in the event of phase deviations between INV and SBS, the SBS
blocks.
If switchover with gap is selected (- S3.6 closed), the SBS does not
block in the event of a phase deviation (see chapter 4.12).
4.12 Signalling, Displays and Remote Signals (X4)
The following signals are indicated via LEDs on the front panel:
Display Colour Operating status
SBS
operation
green SBS is in operation,
operating voltage present
INV present green INV voltage present
Mains
present
green Mains voltage present
Synchronism green Mains and INV run synchronously
Load on INV green The INV supplies the load
Load

green The mains supplies the load
Collective
fault
red Collective fault signal delayed by 20 s,
the signalling relay is triggered at the same
time.
The unit is equipped with a liquid-crystal display.
The following displays are to be expected during the corresponding
operating statuses.
Mains operation:
"U=230.0V" Load voltage
"I=13.7A" SBS current
