3.2.2. Grounding the ICRL-U-8M12-G60
Use the following information to ground the ICRL-U-8M12-G60:
•Use a suitable wire diameter for the functional grounding. Pepperl+Fuchs recommends a wire diameter of
0.5 mm² (AWG20).
•Use toothed washers to ensure good electrical conductivity at the connection.
•Ground the device via an M4 screw.
Note: The grounding screw is not included with the product and
must be supplied by the installation personnel.
Use the following information to ground the ICRL-U-8M12-G60:
•Ground the ICRL-U-8M12-G60 is by means of a separate
ground connection on the ICRL-U-8M12-G60.
•Ground the ICRL-U-8M12-G60 before connecting any other
cables.
•Disconnect the ground only after disconnecting all of the other
cables.
3.3. Wiring the Connector for the Supply
Voltage
The following requirements need to be met before wiring the power supply.
•The power supply cable is suitable for the voltage, the current and the physical load. Pepperl+Fuchs
recommends a wire diameter of 0.5 mm² to 0.75 mm² (AWG20 up to AWG18).
•The permitted cable diameter for connector PG7 is 0.15 in (4 mm) to 0.23 in (6 mm). To ensure the
watertightness of the ICRL-U-8M12-G60, only use voltage supply cables with a diameter within the
specified range.
•Make sure that you can easily disconnect the ICRL-U-8M12-G60 from the main voltage.
Note: The supply voltage can be connected redundantly. Both plus connections are uncoupled. There is no
distributed load. With redundant supply, the power supply unit with the higher output voltage supplies
the device on its own.
When you connect the supply voltage, the ICRL-U-8M12-G60 starts up.
