screwdriver before installing it onto the module.
Cage Clamp
Follow these steps to wire a cage clamp.
1. Strip 9.5 mm (3.8 in.) maximum length of wire.
2. Insert the wire into the open terminal on the side.

The open section at the bottom of the RTB is called the strain relief area. The
wiring from the connections can be grouped with a plastic tie.
