cable (ground) from the engine generator assembly. All
connections must be clean and tight. Check the electrolyte
(fluid) in the battery periodically to be sure it is above the
plates. Never allow the battery to remain in a discharge
condition.
CAUTION: EQUIPMENT DAMAGE
NEVER JUMP START these units. Doing so will destroy
the engine control module, rendering the unit non-
operational. Remove and fully recharge the battery before
attempting to start.
CONNECTING BATTERY CHARGER
A two-stage battery tender is provided on all PSS series
generators. This battery tender charges at a rate of 750 mA
until the battery is fully charged and then automatically
switches to a 13.2 VDC float charger. The charger has an
indicator light on it. Red indicates it is charging, and green
indicates it is in storage mode (float charge). This charger is
mounted on the generator set which is located behind an
access cover in the rear of the unit.
The battery tender receptacle is to be powered by a GFCI
circuit and installed in accordance with the United States
National Electric Code. These AC wires can be run in the
same conduit as the other AC leads from the generator. It
is suggested that this circuit be fused for 15 Amps. Terminal
block connections have been provided in the customer
connection area of the engine-generator set. See following
diagram.

and maintain a fully charged battery.
