Battery, load lead, and remote switch panel connections
are needed to complete the installation. Make final
connections to the battery only after all other
connections have been made as this will prevent
unintentional starting. Some specific details on each
connection are stated in the following paragraphs.
Refer to the wiring diagram for specific details.
Connections should be made only by qualified
electricians. Securely supported or harness all wiring to
the generator set to prevent abrasion.
support is required to prevent exposure to the exhaust
system and drippage of fuel, oil, or grease— at least 2 in.
(51 mm) clearance must be provided between electrical
wiring and hot exhaust parts. Also, do not locate wiring
directly below or in close proximity to fuel system parts
or oil fill tube. Some other points to consider when
making AC load connections are covered in the
following paragraphs.
Wiring connections made at the time of installation
should be accessible for inspection and servicing.

Battery And Connections
A separate 12-volt battery is recommended for the
generator set. With a separate battery, cables can be
kept short which eliminates the problem of excessive
voltage drop through long cables. See Figure 6-15 for
length and sizes. Refer to Figure 6-16 (View A) for cable
connections (note that a ground strap must be
connected between the ground lug on the generator set
and frame of the vehicle with this arrangement).
If the starting battery for the vehicle engine must also be
used for starting the generator engine, the negative
battery terminal must be grounded to the vehicle frame
and heavy gauge (#4) ground strap must connect the
ground lug on the generator set to the vehicle frame as
illustrated in Figure 6-16 (View B).
