3.2.2. Connecting Switched Devices to the RPC-40L8A4
The output terminals on the RPC-40L8A4 back panel are used to connect DC voltage to
each switched device. Each output terminal includes eight connectors (four circuits.)
To connect wires to the DC output terminal block, refer to Figure 3.2 below and proceed
screwdriver with a 3mm wide blade.
Warning: An exposed wire lead from a DC input power source can
conduct harmful levels of electricity. Make certain that no exposed portion
of the DC input wire extends from the terminal block.
1. Prior to inserting a wire into the the DC terminal block, you must use loosen the
retaining screw in order to allow the wire to enter the wire hole. Use a screwdriver
with a 3mm wide blade to turn the retaining screw all the way to the left
2. Firmly insert the wire into the wire hole and push the wire into the hole until
resistance is felt.
3. While holding the wire in place, use a screwdriver with a 3mm wide blade to tighten
the retaining screw. The screwdriver that is used to tighten the retaining screw must
be narrow enough to reach the retaining screw unobstructed. Note that in order to
properly secure the wire, you must push down on the screwdriver while tightening
the retaining screw until the screw is firmly seated.
Caution: Do not over tighten the retaining screws. The recommended
maximum torque is 4.5 lbf-in (72 ozf-in.)
4. Tug on the wire to make certain that the wire is firmly held in place.
