Mounting Guidelines

The transfer switch system circuitry is enclosed in a
NEMA Type 3R enclosure suitable for indoor/outdoor use.
Guidelines for mounting the enclosure include:
• Install enclosure on a firm, strong support structure.
• The transfer switch enclosure 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 putting washers between
the enclosure and the mounting surface.
• DO NOT install the transfer switch where too much
corrosive substances could fall onto the enclosure.
• Protect the switch at all times against excessive moisture,
dust, dirt, lint, construction grit and corrosive vapors
A typical automatic transfer switch installation is shown in
Figure 1. It is best if the transfer switch is mounted near the
utility watt-hour meter, either inside or outside. Speak to the
owner about layout suggestions and changes before you start
the system installation process.

NOTICE Before you drill conduit entry holes, or other
holes, protect the switch and electronics with a cover.
This prevents dirt and metal fragments from entering the
mechanical and electrical components. Failure to do so
could result in damage or malfunction of the switch. Wiring
to generator must be enclosed in conduit.
NOTICE Use a vacuum to clean any dirt or metal
shavings inside the transfer switch. Do not use a blower
or compressed air to clean the inside of the transfer switch
because debris may become lodged in the electrical and
mechanical components causing damage or malfunction.

Power Wiring Interconnections

NOTICE Incorrect installation could cause damage to the
circuit boards and shorten their life. If you install the circuit
boards in live circuits it will damage the board, which is not
included in the warranty. ALWAYS disconnect ALL sources
of power before you service the generator.
• Disconnect all power connections before you install
this equipment. Failure to do so could cause internal
damage to the board during electrical connections.
All wiring must be the correct gauge, correctly supported and
protected by conduit. All wiring must be done as specified
by federal, state and local codes, standards and regulations.
Obey the wire type and torque specifications printed on the
terminal blocks, neutral/ground connectors, and installation
instructions.
WARNING
Generator and utility voltage could cause electrical
shock or burn resulting in death or serious injury.
• Installation must be performed by a licensed
professional.
• Disconnect all sources of electricity before installing or
servicing equipment.
• Ground system before applying power.
Use the installer supplied 600VAC or greater copper or
aluminum wire of a gauge that complies with the latest
version of the National Electric Code to complete the
connections between utility power, transfer switch, generator,
main distribution panel, and optional remote modules. Apply
the necessary correction factors and wire size calculations.
1. Set the Generator Circuit Breaker to the OFF position.
2. Set the Generator ON/OFF Switch to the OFF position.
3. Remove the 15 Amp fuse from the generator.
4. Disconnect the utility power to the generator and transfer
switch.
