Connecting the supply voltage
Use a 5-pin M12 plug-in connector to connect the PSS67 device to the external supply
voltage for device supply and load supply. The supply voltage for load supply is not re-
quired for the operation of this device. The device has an M12 socket (X32), which is phys-
ically adjacent to the M12 connector; this is used to forward the device supply and load
supply to other devices.
WARNING!
The current load capacity of the M12 plug-in connectors X31 and X32 is 8 A
per connector. You must ensure that this value is not exceeded. Exceeding
the permitted current load capacity can damage the plug-in connector.
Please note that the connection of the additional supply voltage is not mon-
itored for overload. Please refer to the derating diagram in the section en-
titled

INFORMATION
The functional earth can be connected to pin 5 of the X31 connector or to
the lower fixing screw (X0). We recommend that you connect the functional
