TP-6514 9/09 30 Section 1 Installation
1.8.2 Remote Start Connection
Connect terminals 3 and 4 to the automatic transfer
switch’s engine start terminals or to an optional remote
start/stop switch. Route the engine start leads through
separate conduit from the AC power and load leads.
1.8.3 Grounding
Ground the generator set. The grounding method must
comply with NEC and local codes.
Connect the
grounding strap to the generator set ground lug,
terminal GND inside the controller compartment.
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.
1.8.4 Battery Charger
A battery charger is factory-installed in the battery
compartment to keep the starting battery fully charged.
The battery charger’s DC leads are factory-connected
to the battery. Supply power to the generator set for the
battery charger and carburetor heater as described in
Sections 1.5 and 1.8.1.
RES models: Plug the battery charger’s power cord into
the receptacle on the bottom of the controller junction
box.
TRES (3-phase) models: The battery charger’s power
cord is factory-connected.
Refer to the generator set operation manual for battery
charger operation information.
