Installation

To minimize disturbances caused by other loads in the building, the 3-phase power input to the unit

should be supplied directly from a dedicated power source.

The input feeder circuit should be sized in accordance with the NEC and any local building codes to

assure the feeder’s ability to safely carry the system’s full load current, including losses.

Input feeder conductors should be sized for no more than 2% voltage drop. If operation at undervolt-

age conditions for extended periods of time is desired, the input feeders must be oversized.

The main input feeder must consist of 3-phase conductors, one neutral and one (safety) ground con-

ductor (4W + G).
