Electrical System
Optional Accessory Power
•
Accessory power for optional items (battery
warmer and block heater) should come from a
customer utility supply source (with appropriate
sized breaker), which is also powered by
emergency power during an outage.
•
Optional user installed GFCI receptacles provide a
place to plug in optional battery warmer and block
heater.
NOTE: Remove knockout plug and route accessory
wiring to customer supplied weather-proof junction box.
See
Figure
5-1. Verify that wires do not contact moving
or vibrating engine parts, as abraded wires can result in
electrical problems.
Install Stub Up Cover and Rear Panel
Install five screws with flat washers to secure stub
1.
up cover.
Install four screws with nylon washers to fasten
2.
fascia over control panel.
Connect wiring harness to the switch located in the
3.
customer access assembly housing.
Install rear panel. For best results, first engage
4.
right side of panel and then rotate left side inward
toward enclosure. Alternately work left and right
sides in until slots are aligned with screw holes on
both sides. Install six screws with nylon washers
and tighten until snug.
Transfer Switch Location
The location of the transfer switch is important. Consider
the following:
Locate the transfer switch as close to the
1.
emergency load as practical to avoid interruptions
of the emergency power system due to natural
disasters or equipment failures.
Locate the transfer switch in a clean, dry, well
2.
ventilated location, away from excessive heat.
Allow adequate working space around the transfer
switch. Refer to the latest NEC, state and local
AHJ requirements for details.
Install power and control wires as per NEC
3.
requirements. In a three phase system, all power
conduits from the generator set must contain all
three phases.
Conduit, wire, circuit protective device sizes,
4.
insulation etc. must conform to applicable local and
national codes and regulations.

General Safety Precautions
WARNING
Explosion. Batteries emit explosive gases while charging.
Keep fire and spark away. Wear protective gear when
working with batteries. Failure to do so could result in
death or serious injury.
WARNING
WARNING
Explosion. Batteries emit explosive gases.
Always connect positive battery cable first to
avoid spark. Failure to do so could result in
death or serious injury.
WARNING
Environmental Hazard. Always recycle batteries at an
official recycling center in accordance with all local
laws and regulations. Failure to do so could result in
environmental damage, death or serious injury.
Always recycle batteries in accordance with local laws
and regulations. Contact your local solid waste collection
site or recycling facility to obtain information on local
recycling processes. For more information on battery
recycling, visit the Battery Council International website

•
Stationary emergency generators installed with
automatic transfer switches will crank and start
automatically when NORMAL (UTILITY) source
voltage is removed or is below an acceptable
preset level. To prevent automatic startup and
possible injury to personnel, do not connect battery
cables until NORMAL source voltage at the
transfer switch is correct and the system is ready to
be placed into operation.
•
Storage batteries give off explosive hydrogen gas.
This gas can form an explosive mixture around the
battery for several hours after charging. The
slightest spark can ignite the gas and cause an
explosion. An explosion can shatter the battery and
cause blindness or other injury. Any area that
houses a storage battery must be properly
ventilated. Do not allow smoking, open flame,
sparks, or any spark producing tools or equipment
near the battery.
