Installation Section (continuation of page 5)
The forced air design of the MaxPac series allows mounting in any direction. It is essential that air flow through the enclosure be planned to insure proper cooling.
The 100 amp through 300 amp open design MaxPac allow the input line power to connect from either of two directions. The output power can only be connected from one direction. The three mounting configurations
are shown below (MaxPac II Three-Phase Two-Leg Shown).
Open designs above 300 amps and all closed designs allow incoming and outgoing wiring in either direction.
