Installation Guide

Mounting the Auto-transformer
1.
Determine the mounting location, on a wall, stud framing or pole. To allow proper
heat dissipation and cable entry, maintain the following minimum clearance areas
between the auto-transformer and other objects:
8 in / 200 mm to the top and bottom of the auto-transformer; if conduit entry to
the auto-transformer will be from the bottom, leave sufficient clearance for the
conduits as well.
4 in / 100 mm to the right and left of the auto-transformer.
2. Install the bracket with the flat side facing down. Verify that the bracket is firmly
attached to the mounting surface.
3. Hang the auto-transformer on the bracket: Lift the auto-transformer from the sides,
or hold it at the top and bottom to lift the unit into place.
4.
Insert the two supplied screws through the outer heat sink fin on both sides of the
auto-transformer and into the bracket. Tighten the screws with a torque of 4.0 N*m
/ 2.9 lb.*ft.
