2.4 Wiring the connectors for supply voltage
and signal contact
The supply voltage and the signal contact are connected by means of a 5 pin
M12 connector.
You find the prescribed tightening torque in General technical data section
on page
34 .
The supply voltage can be connected redundantly. Both inputs 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. The
supply voltage is electrically isolated from the housing.
Note: With non-redundant supply of the mains voltage, the device reports a
power failure. You can prevent this message by applying the supply voltage
via both inputs, or by changing the configuration in the Management.
 The power supply cable is suitable for the voltage, the current and the
physical load. Hirschmann recommends a wire diameter of 0.5 mm² to
0.75 mm² (AWG20 up to AWG18).
 The permitted cable diameter for connector ELWIKA 5012 PG7 is 4 mm
to 6 mm. To ensure the watertightness of the OCTOPUS
8M/16M/24M/OS32 device, only use voltage supply cables with a
diameter within the specified range.

Use a back-up fuse suitable for the supply network.
See “General technical data” on page 34.

Make sure that the disconnecting device is easily accessible for
disconnecting the device from the mains voltage.
Note: Connectors are not electrical isolating devices. Therefore, first plug the
connector into the power supply plug and then switch on the power supply.

Mount the connector for the supply voltage and the signal contact on the
front of the device.
