Note The color coding of the DC-input power supply leads depends on the color coding of the DC power source at your site. Make certain the lead color coding you choose for the DC-input power supply matches lead color coding used at the DC power source.

Note Use 12 AWG (2.5 mm) copper wire only with hex or loop connectors. Ring terminals must be UL approved and suitable for 12 AWG wire.

Step 4 Using the number 2 Phillips screwdriver, securely fasten the protective plate to the terminal block. Step 5 Connect the DC power line input leads to the DC power source through a fast 10A circuit breaker. Step 6 Turn the on/off switch to the on (⏐) position.

Step 7 Look at the IN and OK LEDs on the power supply unit and the corresponding Power LED on the front panel. If the new DC-input power supply unit is operating properly, these LEDs will be glowing green.
