Batteries present the hazard of explo-
sion, which can result in severe personal injury. Dis-
connecting battery cables from the battery while the
generator set is cranking or running causes arcing.
For this reason, do not disconnect battery cables
from the battery while the generator set is cranking
or running. To minimize arcing, always disconnect
the negative (-) cable first, and connect it last.

Reversed battery polarity can damage
or destroy the generator within 3 minutes if stopped,
or within 5 seconds if running. With reversed polar-
ity, alternator windings will be damaged almost in-
stantly if the battery charging circuit is shorted be-
tween resistor R21 and the B1 end of the charging
winding. Make certain that battery polarity is cor-
rect, to avoid damaging or destroying the system.
See the Specifications section of this manual for the 12
volt battery minimum requirements. Connect battery
positive (+) to starter engaging solenoid terminal post,
Figure 4-13. Connect battery negative (-) to a solid
ground connection on the engine.
OPTIONAL ALARM
The GND terminal on the remote control terminal block is
intended for a customer-supplied alarm at a remote loca-
tion, to warn of emergency shutdown. Refer to the Wiring
Diagram for proper alarm connections.
REMOTE START-STOP SWITCH (Optional)
Use 2 wires to connect the SPST remote start-stop
switch to the terminal block marked B+ and to the remote
in the control box, using the wire sizes listed in Figure
4-14.
Incorrect connections can damage the
control, the remote switch, and the interconnecting
wiring. Ensure that the leads from the remote switch
connect with the corresponding terminals on the
generator set.
