**** CAUTION ****
EQUIPMENT DAMAGE - Always connect the posi-
tive cable first and the negative cable last. When
disconnecting, remove the negative cable first and
the positive cable last. Failure to connect and dis-
connect in the proper sequence can cause equip-
ment damage.
Observe polarities: connect the positive (+) battery
terminal to the (+) cable from the engine starter;
the negative (-) battery terminal is connected to the
negative cable (ground) from the engine generator
assembly. All connections must be clean and tight.
Check the electrolyte (fluid) in the battery periodi-
cally to be sure it is above the plates. Never allow
the battery to remain in a discharged 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 THE 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 3.2 VDC float
charger. The charger has an indicator light on it,
red indicates it is charging, and green indicates it is
in the storage mode (float charge). This charger is
mounted on the generator set, located behind an ac-
cess cover on the right side 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 the
other AC leads from the generator. It is suggested
that this circuit be fused for 5 amps. Terminal block
connections have been provided in the customer
connection area of the engine generator set. See
Page 0 for diagram.
** NOTICE **
The battery tender is not intended to recharge a bat-
tery which has become completely discharged. It is
designed to produce enough current to recharge a
slightly low battery, maintaining it fully charged.
MOUNTING THE AUTOMATIC
TRANSFER SWITCH (ATS)
******************
***** WARNING *****
******************
EQUIPMENT DAMAGE - Protect the switch from
construction grit and metal chips to prevent mal-
function or shortened life of the switch. Contactors
returned for warranty consideration with foreign
materials inside of them will not be warranted.
Before installing the ATS you must first ensure that
the transfer switch is large enough to handle your
complete distribution panel. If you are installing a
00 amp transfer switch the main line circuit breaker
must not be larger than 00 amps. If you have a
25, 50, 200 amp or larger system and want to use
a 00 amp transfer switch, you will not be able to
transfer the complete electrical system. In this case
it will be necessary to install a secondary emergency
distribution panel. NOTE: THE MAXIMUM OUT-
PUT OF THE GENERATOR IS 62.5 AMPS AT 240
VOLTS.

NOTICE - CLASS 1 WIRING METHODS ARE TO
BE USED FOR ALL FIELD WIRING CONNEC-
TIONS TO TERMINALS OF A CLASS 2 CIRCUIT.
******************
***** WARNING *****
******************
A main line circuit breaker has been provided inside
the generator housing. During all wiring installation
make sure the breaker is in the off position and the
generator operators switch is in the off position.
Note: This symbol always indicates
ground where used.
GENERATOR CONNECTIONS
Minimum conductor sizes between the generator
and the ATS. Based on wire type and temperature
rating. Wire has been derated for 40° C ambient
temperatures.
