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
