Mounting The Auto-Transformer; Installing The Backed-Up Loads Panel - SolarEdge StorEdge Solution with Backup Installation Manual

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.
