Cut the leads to the length required and route the leads
to the ATS. Add conduit if required by local codes. Refer
to Figure 2-14 and the wiring diagram in Section 3 for
the wiring kit connections. Connect and ground the
system in accordance with the NEC and all applicable
local codes.

Power Supply

Power must be supplied to the generator set location for
the battery charger and the optional carburetor heater.
A 120 VAC receptacle is located inside the air intake
compartment. Power to the receptacle must be
supplied through leads in the wiring kit harness. See
Figure 2-14.
Connect the power leads to a 120 VAC circuit in the
essential loads panel so that the battery charger is
powered by the generator set when utility power is not
available. Figure 2-15 lists the power requirements for
the battery charger and accessories.

Kohler generator sets are shipped with the generator
neutral attached to the generator in the junction box. At
installation, the neutral can be grounded at the
generator set or lifted from the ground stud and isolated
if the installation requires an ungrounded neutral
connection at the generator. The generator set will
operate properly with the neutral either bonded to
ground or isolated from ground at the generator.
Various regulations and site configurations including the
National Electrical Code (NEC), local codes, and the
type of transfer switch used in the application determine
the grounding of the neutral at the generator. NEC 2002
Section 250.20 is one example that has a very good
explanation of the neutral grounding requirements for
generators.

blindness and burn skin.
Battery electrolyte is a diluted sulfuric acid. Battery acid
can cause severe injury or death. Battery acid can cause
blindness and burn skin. Always wear splashproof safety
goggles, rubber gloves, and boots when servicing the battery.
Do not open a sealed battery or mutilate the battery case. If
battery acid splashes in the eyes or on the skin, immediately
flush the affected area for 15 minutes with large quantities of
clean water. Seek immediate medical aid in the case of eye
contact. Never add acid to a battery after placing the battery in
service, as this may result in hazardous spattering of battery
acid.
Battery acid cleanup. Battery acid can cause severe
injury or death. Battery acid is electrically conductive and
corrosive. Add 500 g (1 lb.) of bicarbonate of soda (baking
soda) to a container with 4 L (1 gal.) of water and mix the
neutralizing solution. Pour the neutralizing solution on the
spilled battery acid and continue to add the neutralizing
solution to the spilled battery acid until all evidence of a
chemical reaction (foaming) has ceased. Flush the resulting
liquid with water and dry the area.
