Connecting a 3-kW DC Power Supply to a DC Power Source
1
Note
The terminal box has four slots for four power terminals (ordered as negative [-], positive [+], positive [+],
and negative [-]). Each terminal has two nuts that you use to fasten a power cable to the terminal.
d) Remove the two nuts from each terminal post in each slot of the terminal box.
e) Place each of the lugs for the two positive cables on the two middle terminal posts and fasten each lug using two
nuts. Then tightened to 40 in-lb (4.5 N·m) of torque.
f) Place each of the lugs for the two negative cables on the two side terminal posts and fasten each lug with two nuts.
Then tightened to 40 in-lb (4.5 N·m) of torque.
g) Replace the safety cover on the terminal box and fasten it in place using its three screws.
h) Connect the other ends of the power cables to the two DC power circuits.
Be sure that the positive and negative cables that are attached to one side of the power supply are attached to the same
DC power source circuit. The negative cable is attached to a negative terminal and the positive cable is attached to
a positive terminal).
Step 3
Power up the power supply as follows:
a) Turn on the power source circuit breaker for both input lines.
Verify that the Input 1 (IN1) and Input 2 (IN2) LEDs light up on the power supply.
b) Turn the power switch on the power supply to ON (labeled 1 on the power supply).
The LEDs flash and then the OK LED turns on (green) in addition to the Input LEDs.
