*****CAUTION*****
EQUIPMENT DAMAGE - Always connect the positive
cable first and the negative cable last, when disconnect-
ing, it is negative cable first and positive last. Failure to
connect and disconnect in the proper sequence can
cause equipment damage.
Observe polarities: connect the positive (+) battery
terminal to the (+) cable from the control panel; 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 periodically 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 automati-
cally 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 the storage mode (float charge).
This charger is mounted on the engine generator set in
the same location as the other AC and DC connections.
The battery tender receptacle is to be powered by a GFCI
circuit and installed in accordance wth the United Startes
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 Page 8 for diagram.
** NOTICE **
The battery tender is not intended to recharge a battery
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 (A.T.S.)
*************
***** WARNING *****
*************
EQUIPMENT DAMAGE- Protect the switch from con-
struction grit and metal chips to prevent a malfunction or
shortened life of the switch. Contactors returned for
warranty consideration with foreign material inside of them
will not be warranted.
The Automatic Transfer Switch connects the load (lights,
furnace, outlets, etc.) to the normal power line during
standby. When normal power fails, the A.T.S. starts the
engine generator set, disconnects the power line and then
connects the load to the standby generator set. When
normal power is restored, the automatic switch retransfers
the electrical load to the normal service and stops the
engine. The A.T.S. panel should be mounted as close to
the distribution panel as possible.
*************
***** WARNING *****
*************
All wiring must be done by a licensed electrician, and
must conform to the national electrical code and comply
with all state and local codes and regulations. Check with
your electrical inspectors before proceeding!
************
***** DANGER *****
*************
Be certain the operation selector switch on the front of the
A.T.S. Control is in the “stop” position and the main power
switch “off”. For your own protection, verify these impor-
tant safety precautions yourself with reliable instruments
before proceeding.

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
operation switch is in the off position.
