Mounting Guidelines

The Automatic Transfer Switch is enclosed in a NEMA Type
3R enclosure suitable for indoor/outdoor use. Guidelines for
mounting the Automatic Transfer Switch include:
• Install the switch on a firm, sturdy supporting structure.
• The switch must be installed with minimum NEMA 3R
hardware for conduit connections.
• To prevent switch contact distortion, level and plumb the
enclosure.This can be done by placing washers between
the switch enclosure and the mounting surface.
• NEVER install the switch where any corrosive substance
might drip onto the enclosure.
• Protect the switch at all times against excessive moisture,
dust, dirt, lint, construction grit and corrosive vapors.
A typical installation of the Automatic Power Transfer
Switch is depicted in Figure 2. It is best if it is mounted
near the utility meter, either inside or outside. Discuss
layout suggestions/changes with the owner before beginning
the system installation process.
