Mounting hardware for each mounting option supplied.
Conduit entrances to the back box should – selected to provide sufficient wiring clearance for the installed product.
Use Steel City #53151 (1-1/2” deep) or #53171 (2-1/8” deep) extension rings (as noted in the mounting options). Or equal with the same cut-out area.
Terminating field wires, do not use more lead length – required.
Excess lead length could result in insufficient wiring space for the appliance.

Use care and proper techniques to position the field wires in the back box. They use minimum space and produce minimum stress on the product. This – important for stiff, heavy gauge wires. And wires with thick insulation or sheathing.
Do not pass additional wires through the back box. The back box can – of sufficient size to permit additional wiring as described in NEC 314.16 (B)”. Such additional wires could result in insufficient wiring space for the appliance.
