 Be sure the AUTO/OFF/MANUAL switch is set to
the OFF position before connecting the battery
cables. If the switch is set to AUTO or MANUAL,
the generator can crank and start as soon as
the battery cables are connected.
 Be sure the utility power supply is turned off
and the 7.5A fuse is removed from the generator
control panel, or sparking may occur at the bat-
tery posts as the cables are attached and cause
an explosion.
Servicing of the battery is to be performed or supervised by per-
sonnel knowledgeable of batteries and the required precautions.
Keep unauthorized personnel away from batteries.
See the Specifications section for the correct size and rating when
replacing the battery. Have these procedures performed at the
intervals specified in the "Service Schedule." A negative ground
system is used. Battery connections are shown on the wiring dia-
grams. Make sure the battery is correctly connected and terminals
are tight. Observe battery polarity when connecting the battery to
the generator set.

1.15 BATTERY CHARGER

These generators DO NOT contain an internal battery
charger.
The manufacturer provides a battery trickle charger
that is active when the unit is set up for automatic
operation. With the battery installed and utility power
source voltage available to the transfer switch, the
battery receives a trickle charge to prevent self-
discharge. The trickle charger is designed to help
extend the life of the battery by maintaining the bat-
tery. The trickle charge feature cannot be used to
recharge a discharged battery.
A separate battery charger module is included with the generator.
(For battery charger installation, see the Generator Install Guidelines
included with the unit.)
2.1 BEFORE INITIAL START-UP
These units have been run and tested at the factory
prior to being shipped and do not require any type
of break-in.
Before starting, complete the following:
1. Set the generator's main circuit breaker to its OFF (or OPEN)
position.
2. Set the generator's AUTO/OFF/MANUAL switch to the OFF
position.
3. Turn OFF all loads connected to the transfer switch terminals
T1 and T2.
4. Check the engine crankcase oil level and, if necessary, fill to
the dipstick FULL mark with the recommended oil. Do not fill
above the FULL mark.

NOTE:
5. Check the fuel supply. Gaseous fuel lines must have been
properly purged and leak tested in accordance with applicable
fuel-gas codes. All fuel shutoff valves in the fuel supply lines
must be open.
During initial start up only, the generator may exceed the normal
number of start attempts and experience an "over crank" fault (See
the "Overcrank" section). This is due to accumulated air in the fuel
system during installation. Reset the control board and restart up
to two more times, if necessary. If unit fails to start, contact the
local dealer for assistance.
 Never operate the engine with the oil level
below the "Add" mark on the dipstick. Doing this
could damage the engine.
2.2

ELECTRICAL CHECKS

Complete electrical checks as follows:
1. Set the generator's main circuit breaker to its OFF (or OPEN)
position.
2. Set the generator's AUTO/OFF/MANUAL switch to the OFF
position.
3. Turn OFF all loads connected to the transfer switch terminals
T1 and T2.
4. Turn on the utility power supply to the transfer switch using
the means provided (such as a utility main line circuit break-
er).
DANGER
 The transfer switch is now electrically "hot."
Contact with "hot" parts will result in extremely
hazardous and possibly fatal electrical shock.
Proceed with caution.
5. Use an accurate AC voltmeter to check utility power source
voltage across transfer switch terminals N1 and N2. Nominal
line-to-line voltage should be 240 volts AC.
6. Check utility power source voltage across terminals N1 and
the transfer switch neutral lug; then across terminal N2 and
neutral. Nominal line-to-neutral voltage should be 120 volts
AC.
7. When certain that utility supply voltage is compatible with
transfer switch and load circuit ratings, turn OFF the utility
power supply to the transfer switch.
8. On the generator panel, set the Auto/Off/ Manual switch to
MANUAL. The engine should crank and start.
9. Let the engine warm up for about five minutes to allow inter-
nal temperatures to stabilize. Then, set the generator's main
circuit breaker to its ON (or closed) position.
DANGER
 Proceed with caution! Generator power voltage
is now supplied to the transfer switch. Contact
with live transfer switch parts will result in dan-
gerous and possibly fatal electrical shock.
