11.1 Remote Signalling
The remote signalling PCB consists of a remote signalling master
board A12 and an expansion board A13, the contacts of which are
connected to terminal block X12.
The remote signalling boards have the following inputs and outputs:
Inputs (via optocoupler):
• INV remote shutdown
Outputs (via relay contacts):
• Inverter operation
• Mains operation
• Rectifier fault (REC or REC circuit fault)
• Battery undervoltage
• Collective fault (REC, INV, SBS or battery fault)
• SBS blocked
• Fan fault
• REC circuit fault
i
NOTE:
The maximum load for the relay contacts is 250 V / 8°A AC.

NOTE:
The A13 and A14 expansion board can be programmed. See the
technical data sheet for terminal assignment.
The maximum input voltage for terminal X5 is 24 V AC/DC.
When a signal is received, the contacts on X3 close on the two
contact points with the lower numbers on the connection terminal.
The contacts on X4 close on the two connection terminals with the
higher numbers (fail-safe principle).
The control and message lines are routed to the bottom using the
cable duct in the centre of the unit.
