Connections to Field Expansion Module Mounting Assembly
The field expansion module mounting assembly provides separate AC input connections for each rectifier.
Circular openings are provided in the side panels (side feed) and rear covers (rear feed) of the module
mounting assembly for AC input and AC input equipment-grounding conductors. The openings accept 3/4"
inch conduit fittings. AC input wiring should be provided to all mounting positions intended for rectifiers,
including currently unused positions. This wiring will ease future installation of rectifiers to meet increased load
requirements.
NOTE!
A grounding conductor must be provided with each conduit.
