*****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 genera-
tor 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 provide 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 de-
signed 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 construc-
tion 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!
Before installing the A.T.S. you must first ensure that the
transfer switch is large enough to handle your complete
distribution panel. See Figure 3. i.e. If you are installing a
100 amp transfer switch the main line breaker must not
be larger than 100 Amps. If you have a 125, 150 , 200
Amp or larger system and want to use a 100 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. See Figure 4. NOTE: THE MAXIMUM OUTPUT OF
THE GENERATOR IS 50 AMPS AT 240 VOLTS. You must
also take this into consideration when deciding whether
to install an emergency distribution panel.

***** 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
operation switch is in the off position.

To gain access to the customer connections remove the
end panel opposite the hot air discharge end. All
connections including AC & DC connections to the ATS,
120 Volt power connection for battery charger, and battery
installation are made behind this panel. After removing
the end panel you will need to remove the cover over the
connection box in the upper right hand corner. Knockouts
are provided on the outside of the enclosure for your
convenience. See page 13 for unit layout.
Four AC power leads are required between the generator
and the A.T.S.; Two hot leads a neutral and a ground
lead. You will then need to run both a neutral and a
ground lead in addition to the two power leads all the way
back to your distribution panel. The two power leads
from the generator are marked G1 and G3.
