STEP 4 | Crimp a 6-AWG wire to the provided grounding lug and connect the other end to your earth
ground point.
STEP 5 |
Connect the two-post lug connector to the two-post studs on the chassis using the provided
star washers and nuts and then torque the nuts to 50 in-lbs. Be careful not to strip the nuts
and lug studs.
STEP 6 | Power off your DC power feed.
STEP 7 |
Connect each of the four DC power supplies to a -48VDC power source using the provided
DC power cables.
1. Crimp the bare wire ends of the cables using lugs (not included) designed for your DC
power source. Each cable has two red (posive) and two black (negave) wires. Crimp
the two black wires together and connect to your DC negave terminal and then crimp
the two red wires together and connect to the posive terminal. Do this for each of the
four power supplies, ensuring that the first two power supplies on the le are connected
to one power circuit breaker and the second pair on the right is connected to a different
circuit breaker. This ensures power redundancy and allows for planned electrical circuit
maintenance.
2. Connect the other ends of the DC cables to the front of the DC power supplies by
pushing the plasc connector into the DC power supply unl it clicks into place. Ensure
that you connect each pair of power supplies to a different circuit breaker.
When cabling the DC power supply to your power source, ensure that you route the
cable in such a way that it does not put pressure on the plasc clips located at the
front of the DC power supplies. It is best to route the cables first and then plug the
cables into the power supplies.
