Connecting alarm and fault relays
Connect the alarm and fault equipment to the ALARM and FAULT relays.
Each potential-free relay output is activated in an alarm or fault situation
respectively. The fault relay output is activated (a short circuit between the
common (C) and normally closed (NC) terminals of the relay) when there is no
fault.
The maximum contact rating for each relay circuit is 2 A at 30 VDC.
Connecting expansion boards
Caution:
Risk of equipment damage. Always disconnect the control panel from
the mains power supply before installing an expansion board.
See your expansion board installation sheet for detailed installation information.
