INSTALLING THE BATTERY
**** CAUTION ****
EQUIPMENT DAMAGE - In the following battery installation
procedure, check to be sure the selector switch remains in the
“stop” position.
A customer supplied twelve-volt BCI group 24 battery rated 650
CCA (minimum) is required to complete the installation. Install
the highest CCA rated battery available for best cold weather
starting performance.
****WARNING*****
EQUIPMENT DAMAGE - Always connect the positive battery
cable first and the negative cable last. When disconnecting a
battery always disconnect the negative cable first and the
positive cable last. Failure to follow these steps can cause
arcing at the battery post which can cause damage to both the
engine and the engine control module.
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.
NOTE: Alway make sure that a new battery is fully charged
before installing it on a generator set. Failure to do so can cause
damage to the engine control module in the generator set.
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.
A self tapering trickle charger, producing up to 40 MA is built into
the Automatic Transfer Switch panel to keep the battery in top
condition during standby periods. A small green light on the
Transfer Switch cover is illuminated to indicate the proper
operation of the charger. Since the charger has an automatic
charge regulation circuit, the charger has no control knob and
requires no adjustment.
** NOTICE **
The trickle charger is not intended to recharge a battery which
has become completely discharged. It is designed to produce
just enough current to maintain a fully charged battery.
MOUNTING THE AUTOMATIC TRANSFER
SWITCH (A.T.S.)
The automatic transfer switch connects the load (lights, furnace,
outlets, etc.) to the normal power line. 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 retrans-
fers 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.

FIRE HAZARD - All wiring must be done by a licensed electri-
cian, and must conform to the national electrical code and comply
with all state and local codes and regulations. Check with the
authorities before proceeding!
PSS20000LS - The Automatic Transfer Switch shipped with the
PSS20000LS system has a 225 Amp line side contactor (the 277/
480 volt transfer switch has 100 Amp contactor instead of the 225
Amp) installed to handle your normal power needs and a 100
Amp generator side contactor to handle the emergency generator
output. Before installing the A.T.S. you must first ensure that the
225 Amp line side contactor will be sufficient to handle your
complete service. See Figure 5. (i.e. the main line breaker must
not be larger than 225 Amps) If you have 250, 300 Amp or larger
system, 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.
PSS35000 - The Automatic Transfer Switch shipped with the
PSS35000 system has a 225 Amp line side contactor (the 277/
480 volt transfer switch has 100 Amp contactor instead of the
225 Amp) installed to handle your normal power needs and a
225 Amp generator side contactor to handle the emergency
generator output. Before installing the A.T.S. you must first
ensure that the 225 Amp line side contactor will be sufficient to
handle your complete service. See Figure 5. (i.e. the main line
breaker must not be larger than 225 Amps) If you have 250, 300
Amp or larger system, 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.
PSS70000 - The Automatic Transfer Switch shipped with the
PSS70000 system has a 400 Amp line side contactor (the 277/
480 volt transfer switch has 225 Amp contactor instead of the
400 Amp) installed to handle your normal power needs and a
400 Amp generator side contactor to handle the emergency
generator output. Before installing the A.T.S. you must first
ensure that the 400 Amp line side contactor will be sufficient to
handle your complete service. See Figure 5. (i.e. the main line
breaker must not be larger than 400 Amps). If you have a larger
main line breaker, 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.

***** WARNING *****
*************
PERSONAL INJURY - 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
important safety precautions yourself with reliable instruments
before proceeding.
