Mounting Guidelines

The model 01917 automatic transfer switch is enclosed in a
NEMA Type 1 enclosure suitable for indoor use only. Model
01918 is identical circuitry enclosed in a NEMA Type 3R
enclosure suitable for indoor/outdoor use.
Guidelines for mounting the switch enclosure include:
• Model 01918 automatic transfer switch must be
installed with minimum NEMA 3R hardware for
conduit connections.
• Install the switch on a firm, sturdy supporting structure.
• 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 indoor transfer switch installation is depicted
below. Discuss layout suggestions/changes with the owner
before beginning the system installation process.

NOTICE Before drilling conduit entry holes, or any
other holes, cover and protect the switch and electronics
to prevent dirt and metal fragments from entering the
mechanical and electrical components. Failure to do so may
result in damage or malfunction of the switch.
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

WARNING Low voltage wire cannot be installed in
same conduit as power voltage wiring.
• Failure to follow above warning could cause personal
injury, damage and/or malfunction of equipment.
All wiring must be the proper size, properly supported and
protected by conduit, if applicable. All wiring should be done
per applicable federal, state and local codes, standards and
regulations. Obey wire type and torque specifications printed
on terminal blocks and neutral/ground connectors.
NOTICE Improper installation can cause damage to the
circuit boards and shorten their life. Installing circuit
boards in live circuits will damage the board and is not
covered by warranty. ALWAYS disconnect ALL sources of
power prior to servicing.
• Remove all power prior to installing this equipment.
Failure to do so could cause internal damage to the board
when making electrical connections.
• Turn generator to OFF position.
• Turn off utility power to the standby generator and
transfer switch.
Complete the following connections between the transfer
switch, main distribution panel, utility power and generator.
Use installer-supplied 300VAC or greater wire that complies
with Table 310.16 in the National Electric Code. Apply the
necessary correction factors and wire size calculations.

1. Set generator's system switch to OFF position.
2. Set generator's circuit breaker to OFF (open) position
and remove 15 Amp fuse from system control panel.
3. Turn off utility power to the standby generator and
transfer switch.
4. Using installer supplied 300VAC or greater wire,
connect utility power supply leads from a 50 Amp
two pole breaker installed in main distribution
panel to transfer switch terminals marked "UTILITY
CONNECTION". Ensure breaker is turned OFF.
5. Using installer supplied 300VAC or greater wire,
connect main distribution panel ground to transfer
switch "GND" bus.
6. Using installer supplied 300VAC or greater wire,
connect main distribution panel neutral to transfer
switch "NEUTRAL" terminal.
7. Using installer supplied 300VAC or greater wire,
connect power supply leads from generator
control panel to transfer switch terminals labeled
"GENERATOR CONNECTION".
