4.1 Introduction
Accessories are available factory-installed and/or
shipped loose. Obtain the most current list of
accessories from the generator set specification sheet
or by contacting your local authorized service distributor/
dealer.
Have accessories installed by a trained, authorized
Kohler distributor, dealer, or authorized representative.
Follow the installation instructions provided with each kit.
Use separate conduit for AC and DC leads to reduce the
possibility of electrical interference. Use shielded cable
for all analog inputs. Verify that the leads and conduit do
not interfere with the operation of the generator set or
obstruct the service areas.
Verify that the accessory installation complies with the
National Electrical Code (NEC) and all applicable local
and state codes.

for the customer-supplied wiring of engine battery-
