Mounting
Mounting dimensions for the transfer switch enclosure
are in this manual. Enclosures are typically wall-
mounted. See
Drawings and Diagrams .
This transfer switch is mounted in a UL/CUL type 3R
enclosure. It can be mounted outside or inside and
should be based on the layout of installation, conve-
nience, and proximity to the utility supply and load center.
Install the transfer switch as close as possible to the elec-
trical loads that are to be connected to it. Mount the
switch vertically to a rigid supporting structure. To pre-
vent switch distortion, level all mounting points. If neces-
sary, use washers behind mounting holes to level the
unit.
