Electrical Installation
General Information
FIRE, ELECTRIC SHOCK OR ARC FLASH
Disconnect all power from all equipment of your machine/process prior to electrical installation
of the device.
Confirm the absence of power using a properly rated voltage sensing device.
Place a "Do Not Turn On" or equivalent hazard label on all power switches and lock them in
the non-energized position.
Failure to follow these instructions will result in death or serious injury.
Wiring of the device depends on the safety-related function to be implemented. Before wiring the
device, engineer the safety-related function, perform a risk assessment with regard to your
machine/process, and determine the suitability of the device as well as the connected equipment.
You can wire the device with the terminal blocks in the device or you can remove the terminal
blocks. For the latter, pull the terminal blocks out of the device, connect the individual terminals and
push the terminal blocks back into the device.
Use 75 °C (167 °F) copper conductors to wire the device.
