POWER AND GROUNDING
Single-Carrier Cabinet System
Each cabinet requires a separate power outlet, as shown in Figures 27 and 28. These outlets
must not be shared with other equipment, must not be under switch control, and should be
located outside the cross-connect field area, if possible. Any available power source can be used
as long as the phase or leg provides 120-volt AC at the required drain.
The Manager I terminal or G3r-MT should be connected to the “Administration Terminal” power
outlet, as shown in Figures 27 and 28.
A system cabinet is UL-listed at 10 amperes, 120 volts, or 1200 watts per cabinet. Therefore, the
power required for a two-cabinet system is 2400 watts, the power required for a three-cabinet
system is 3600 watts, and the power required for a four-cabinet system is 4800 watts.
