Wiring the DC Power
Follow the procedures in this section to wire the DC power.
Note The color coding of DC-input power supply leads depends on the color coding of the DC power
source at your site. Typically, green or green/yellow is used for ground, black is used for +48V
(return), and red or white is used for –48V. Make certain the lead color coding you choose for the
DC-input power supply matches lead color coding at the DC power source.
Note The length of the cable between the –48v power supply and the power feed panel must not exceed
9.4 feet (3m).
