Figure 44: Installing an DC power supply unit
1. Make sure that power is disconnected at the circuit breaker before proceeding.
2. Prepare the power and safety grounding wires using the appropriate size wire, crimp on ring lugs
and heat shrink tube for all three wires. Due to the limited space for the safety ground wire, we
recommend using a 90 angled lug such as:
•
TE Connectivity Solistrand "16-14HD 90 Ring 8", part number 184269-1 for 14 AWG wire
•
PIDG 12-10 Ring #8, 90-DEG, part number 1958340-1 for 12 or 10 AWG wire
3. Remove the previously installed power supply from the appropriate slot by pressing the release lever
and pulling the power supply handle.
4. Before opening the package that contains the DC power supply, touch the bag of the switch casing
to discharge any potential static electricity. It is recommended to use an ESD wrist strap during
installation.
5. Remove the DC power supply from the anti-static shielded bag.
6. Remove the DC terminals plastic cover.
7. Attach the safety grounding wire to the power supply using the safety ground screw.
