Mounting Guidelines
The Automatic Transfer Switch is enclosed in NEMA Type 3R
enclosures suitable for indoor or 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
for Models 071018 and 071019 is depicted in Figure 1. An
alternative installation of the Automatic Power Transfer
Switch is depicted in Figure 2.
It is best if the transfer switch is mounted near the utility
watt-hour meter, either inside or outside. Discuss layout
suggestions/changes with the owner before beginning the
system installation process.
