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. An alternative installation of the Automatic Power Transfer Switch is also depicted. 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.
