Non-Automatic Transfer
Switches (30 – 1200 Amperes)

With the enclosed transfer switch equipment unpacked and
ready for mounting, proceed with the following steps:
Step 1: The transfer switch enclosure door is hinge
mounted with removable hinge pins. To simplify
the mounting procedure and avoid damaging the
door mounted logic panel, carefully remove the
door and set aside in a safe place until mounting
is complete.
Step 2: Install required mounting bolt anchors and the two
upper mounting bolts in the mounting surface.
Step 3: Gently lift the enclosure and guide the elongated
holes in the upper mounting flange over the upper
mounting bolts, but do not completely tighten
the bolts.
Step 4: While still supporting the enclosure, install the
two lower mounting bolts in the lower mounting
flange, but do not completely tighten. Use shims,
if required, to prevent deformation of the enclosure
when the mounting surface is distorted.
Step 5: Tighten all four mounting bolts after any required
shimming is completed.
Step 6: Double check to ensure that all packing and
shipping material has been removed.
