Installation

Connecting the AC Input

Isolation Transformer

The parallel configuration should be supplied with a balanced
3-phase input providing the nominal AC line voltage (plus or minus
the tolerance). To ensure that the AC input is balanced and isolated,
an isolation transformer is recommended.

MOV Protection

The units in the parallel configuration are supplied with MOVs to
handle voltage surges, high phase-to-phase voltages, and high phase-
to-ground voltages. Connecting an input voltage greater than the
listed input voltage tolerance may cause the MOVs to be damaged,
resulting in a continuous current path to ground.

Feeder Bay

The feeder bay allows top or bottom entry, and allows up to 10
connections to be attached for each phase (on alternate sides of the
busbars, if desired). The recommended torque is 45 lb-ft.
