Installation Instructions

To minimize disturbances from other loads in the building, the 3-phase power input to the FPC should be supplied directly from the service entrance or other power source (a dedicated power feeder).

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

Typical conductor size data is shown in Table 4. All connections must comply with the NEC and all other applicable codes.

For units with a transformer, the main input feeder should consist of 3-phase conductors and one (safety) ground conductor (3W + G).

For units without a transformer, the main input feeder must consist of 3-phase conductors, one neu- tral and one (safety) ground conductor (4W + G).
