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 below. It is best if the transfer switch is mounted
near the main distribution panel, either inside or outside.
Discuss layout suggestions/ changes with the owner before
beginning the system installation process.
