Front – A front clearance of three (3) feet is required to open and maintain the unit per

NEC 110.26 or applicable Canadian Electrical Code.

Top – A top clearance of 18 inches above the air intake hood is required to maintain the

lters and blowers.

Clearances are shown in the gure below.

1. Only one side, right or left, is recommended to have the full 36”clearance while the remaining side must

have 12”. The above example demonstrates 12” on the left with 36” on the right side. This allows access

to the magnetics section for retorquing bolts and thermal scan of connections. This is not an NEC setback

requirement and 12” on each side is an acceptable installation practice.
