2. Using a 1/16-inch flat-blade (pocket) insulated screwdriver, loosen the two captive wire
installation screws on the terminal block to accommodate 16-22 AWG solid wire.
3. If you are establishing a color convention for wiring, use black for -48VDC and red for Gnd.
Remove ¼-inch insulation from wire ends. Avoid nicking the wire.
4. Connect the -48 Volt source DC power leads to the terminals on the power supply terminal
block. In so doing, you must strictly observe the following order of connection to the source
power supply wire:
(a) + terminal to red lead (GND)
(b)
- terminal to black lead (-48VDC)
5. Tighten the two captive wire installation screws on the terminal block.
6. Plug the terminal block into the rear of the unit. Verify that the source wires are routed
downward.
