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-

ces cover on the right side of the unit.

The battery tender receptacle is to be powered by

a GFCI circuit and installed in accordane 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, maintainging 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 50 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.

To gain acces to the customer connections remove

the end door panel opposite the muffler. All AC and

DC connections to the ATS, 20 Volt power connec-

tion for battery charger, and battery installation are

made behind this panel. After removing the door

remove the cover over the customer connection box,

using a 7/6 inch open end wrench. See pages 20

and 2 for generator set and pad layout.

Two (2) hot leads, one () neutral and () ground

lead are required between the generator and the

ATS or distribution panel. The two power leads from

the generator are marked G and G3. Next install

two leads, one neutral and one ground lead from the

generator set to the ATS or distribution panel.

In addition to the power leads install a three wire 20

volt, 5 amp circuit from your distribution panel to

the generator. This circuit wll be used to power the

battery charger, optional block heater and optional

battery heater.
