Connecting a 3-kW Universal AC/DC Power Supply to a DC Power Source

The 3-kW Universal AC/DC power supply can be connected to a 240-to-380-V DC circuit equipped with
positive, negative, and ground terminals. This procedure is for connecting the power supply to a DC power
source.
Before you begin
• The DC power source must be turned off at its circuit breaker.
• The power switch on the power supply must be turned off (power switch set to 0).
Step 1
Verify that the circuit breaker for the DC power source is turned off.
Step 2 Verify that the power switch on the power supply is turned off (0).
Step 3
Connect the ground terminal ring on the power cable to the ground terminal on the DC power source. Secure it in place
with a nut tightened to the appropriate torque setting for the terminal post.
Step 4 Connect the negative terminal ring on the power cable to the negative (-) terminal on the DC power source. Secure it in
place with a nut tightened to the appropriate torque setting for the terminal post.
Step 5 Connect the positive terminal ring on the power cable to the negative (+) terminal on the DC power source. Secure it in
place with a nut tightened to the appropriate torque setting for the terminal post.
Step 6 Connect the Saf-D-Grid connector on the other end of the power cable to the Saf-D-Grid receptacle on the power supply.
Step 7
Turn on the circuit breaker for the DC power source circuit.
Step 8 Turn on the power supply by pressing its power switch to on (1).
