Electrical System

Optional Accessory Power

• Accessory power for optional items (battery
warmer and block heater) should come from a cus-
tomer 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: See Figure 5-1. Remove knockout plug and
route accessory wiring to customer supplied weather-
proof junction box. Verify wires do not contact moving or
vibrating engine parts, as abraded wires can result in
electrical problems.
Installing Stub-Up Cover and Rear
Panel
Proceed as follows to install stub-up cover and rear
panel:
1. Install five screws with flat washers to secure stub-
up cover.
2. Install four screws with nylon washers to fasten
fascia over control panel.
3. Connect wiring harness to switch located in cus-
tomer access assembly housing.
4. Install rear panel. For best results, first engage
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:
1. Locate transfer switch as close to emergency load
as practical to avoid interruptions of emergency
power system due to natural disasters or equip-
ment failures.
2. Locate transfer switch in a clean, dry, well venti-
lated location, away from excessive heat. Allow
adequate working space around transfer switch.
See latest NEC, state, and local AHJ requirements
for details.
3. Install power and control wires as per NEC require-
ments. In a three-phase system, all power conduits
from generator must contain all three phases.
4. Conduit, wire, circuit protective device sizes, insu-
lation etc. must conform to applicable national and
local 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
Risk of burns. Batteries contain sulfuric acid and
can cause severe chemical burns. Wear protective
gear when working with batteries. Failure to do
so could result in death or serious injury.
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
at: http://batterycouncil.org
• 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 pre-
set level. To prevent automatic startup and possi-
ble injury to personnel, do not connect battery
cables until NORMAL source voltage at transfer
switch is correct and system is ready to be placed
into operation.
• Storage batteries give off explosive hydrogen gas.
This gas can form an explosive mixture around bat-
tery for several hours after charging. The slightest
spark can ignite gas and cause an explosion. An
explosion can shatter battery and cause blindness
or other injury. Any area that houses a storage bat-
tery must be correctly ventilated. Do not allow
smoking, open flame, sparks, or any spark produc-
ing tools or equipment near battery.
