1.10 ELECTRICAL CONNECTIONS
1.10.1 GROUNDING THE GENERATOR
A GROUNDING LUG is provided on the generator mounting base
for the purpose of grounding the frame and the external electrically
conductive parts of this equipment to an approved earth ground
and/or grounding rods where required by the National Electrical
Code (Figure 1.12). Consult a qualified electrician for grounding
requirements in the area. Grounding procedures must meet local
regulations.

Do not connect the ground wire to any pipe that
carries a flammable or explosive substance –
FIRE or an EXPLOSION may result.
Proper grounding helps protect personnel against electrical shock
in the event of a ground fault condition in the generator or in
connected electrical devices. In addition, grounding helps dissipate
static electricity that often builds up in ungrounded devices.

1.10.2 BATTERY CHARGER CONNECTION
The generator has been equipped with a battery charger integrated
in the control panel. Power leads for the charger have been run to
the connection box (Figure 1.13). Connect the power leads for the
battery charger to the 120 VAC T1/LINE connection and the neutral
lead to the NEU connection. This is a 15 Amp circuit supplied by
the customer.
(Refer to the Connection Diagrams section in this manual, or the
wiring diagram in the Owner's Manual that is supplied with the
unit.)

1.11 BATTERY INSTALLATION

Standby 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 such automatic start-
up and possible injury to personnel, do not
connect battery cables until certain that 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. Such 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.

Battery electrolyte fluid is an extremely caustic
sulfuric acid solution that can cause severe
burns. Do not permit fluid to contact eyes, skin,
clothing, painted surfaces, etc. Wear protective
goggles, protective clothing and gloves when
handling a battery. If fluid is spilled, flush the
affected area immediately with clear water.

Do not dispose of the battery in a fire. The
battery is capable of exploding.

Do not open or mutilate the battery. Released
electrolyte can be toxic and harmful to the skin
and eyes.
