DANGER
If the vehicle's electrical circuits can be powered
by any other source of electricity (such as, a
"dockside" power receptacle), there must be no
possibility of connecting the different power
sources to the vehicle's circuits at the same
time. The dockside (utility) power source must
be positively isolated from the vehicle's circuits
whenever the generator is operating. Failure to
isolate the vehicle's circuits from the dockside
power supply when the generator is running
may result in damage to the generator or in
serious injury or death to dockside (utility)
power workers due to backfeed of electrical
energy. Installation and connection of the gen-
erator must comply with NFPA 70, Article 551,
and NFPA 1192 (latest editions).

BATTERY INSTALLATION
2.7.1
RECOMMENDED BATTERY
Install a battery that meets the following require-
ments:
• The battery must be a 12-volt, automotive-type
storage battery.
• Use a battery with minimum ratings of 70 amp-
hours and 600 cold-cranking amps.
If the battery is to be used to power other vehicle
accessories, as well as to start the generator, a bat-
tery with a larger capacity may be necessary.

BATTERY CABLES
Using battery cables that are too long or too small in
diameter may cause a drop in voltage, which causes
starting problems. For the best cold weather starting,
the voltage drop between battery terminals and the
generator connection point should not exceed 0.12
volts per 100 amps of cranking current.
The generator is rated at about 160 DC amps of
cranking current to operate the starter and glow
plugs.
Select battery cables based on (a) cable length and
(b) prevailing ambient temperatures. Generally, the
longer the cable and the colder the weather, the larger
the cable size must be, as shown in the chart.
CABLE LENGTH in Feet (meters) CABLE SIZE
0 to 10 (0 to 3)
11 to 15 (3.4 to 4.5)
16 to 20 (4.5 to 6)
*For warm weather, use No. 2 cable up to 20 feet.
2.7.3
BATTERY CABLE CONNECTIONS
1. Connect the battery cable from the battery post
or terminal, indicated by a POSITIVE, POS, or
(+), to the insulated lug on the unit frame (Figure
2.19).
Check to be sure the cable boot for the positive
cable has been installed.
