Chapter 3 Installing the Switch

Connecting Source Power to the Chassis

Connecting Source DC to the DC-Input Power Supply

To connect source DC to the DC-input power supply, follow these steps:

Step 1 Ensure that the system (earth) ground chassis connection has been made.

Step 2 Verify that power is off to the DC circuit that feeds the power supply that you are connecting.

As an added precaution, place the appropriate safety flag and lockout devices at the source power circuit breaker, or place a piece of adhesive tape over the circuit breaker handle to prevent accidental power restoration while you are working on the circuit.

Step 3 Verify that the power switch is in the off (0) position on the power supply that you are connecting.

Step 4 Verify that the power supply is fully seated in the chassis power supply bay and that the two captive installation screws on the power supply are tight.

Step 5 Remove the plastic cover from the terminal block.

Step 6 Attach the appropriate lugs to the source DC cables. The maximum width of a lug is 0.300 inch (7.6 mm).

Either insulated crimp-on spade lugs or insulated crimp-on ring connectors can be used on the source DC cables. They should be sized according to local and national installation requirements and electrical codes.

Note The source DC cables should be sized according to local and national installation requirements and electrical codes. Use only copper wire.

Step 7 Connect the DC-input cables to the power supply terminal block in this order:

1.Ground cable to the ground connector on the terminal block

2.Negative (–) source DC cable to the negative (–) connector on the terminal block

3.Positive (+) source DC cable to the positive (+) connector on the terminal block

Step 8 After ensuring that all of the source DC cable connections are secure, reinstall the plastic terminal block cover.

Caution To prevent a short circuit or shock hazard after wiring the DC-input power supply, you must reinstall the terminal block cover.

Caution In a system with dual power supplies, connect each power supply to a separate power source. In case of a power source failure to one supply, the second power source should still be available.

Step 9 Remove any safety flag and lockout devices or any tape from the circuit breaker switch handle, and restore power by moving the circuit breaker switch handle to the on () position.
