IFM4R internal module wiring
Cables:
2/3 wire shielded cable
Proper section (minimum 0.5mm², maximum 2.5 mm²)
Compliant with local laws and regulations in force
Each connection to this output must be completed in accordance with the instructions in
paragraph 4.6.1
.
All voltage free relay contact can only be connected to SELV circuits.
Each of the 4 relay outputs on the module must be connected in accordance with the following wiring diagram:
The OUT output illustrated in the diagram is used as a power source and is programmed as continuously active.
The illustrated connection does not supervise the cable and does not signal connection faults.
EN54:
If you wish to configure a RELAY output as a fault
signalling output, you must complete the connections
as shown in the wiring diagram opposite.
In compliance with the regulations in force, the output
must be configured as “inverted” in order to switch to
fault condition when the system is completely without
power.
Therefore, in stand-by status (no faults present on the
system) terminals C and NC will be closed, whereas
terminals C and NO will be open.
