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 and an alternative installation of the Automatic
Power Transfer Switch is depicted below. It is best if the
transfer switch is mounted near the utility meter, either
inside or outside. Discuss layout suggestions/ changes with
the owner before beginning the system installation process.
