recommendations.
NOTE: Always 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. Depending on your battery
type, check the electrolyte in the battery periodically to be sure it is
above the plates. Never allow the battery to remain in a discharged
condition.
CONNECTING BATTERY CHARGER & BLOCK HEATER
A three-stage battery charger is provided standard on this unit. The
charger is an Automatic Battery Charger & Maintainer. This charger

to 14 Volts. The yellow LED will be on constantly during this stage.
When the charging rate drops to 2.5 Amps, the charge will enter the
ABSORPTION charging mode. During this mode, the yellow LED will

This charger is mounted under the customer connection on the control
side of the generator and plugged into the receptacle mounted in
the AC connection cabinet. The battery charger receptacle is to be
powered by a GFCI circuit and installed in accordance to the US
National Electric Code. It is suggested that this circuit be fused to 20
Amps.
The block heater on this unit is a 750 watt heater can use the same
20 Amp GFCI fused circuit. This circuit will terminate on the 120
Volt terminal block mount in the customer connection cabinet. The
engine blockheater installed on this unit should also be plugged into
this receptacle. The block heater is thermostatically controlled when
plugged in will maintain the engine coolant temperature between 100
and 120 degrees F.
MOUNTING THE AUTOMATIC TRANSFER SWITCH
WARNING: FIRE HAZARD:
All wiring must be done by a licensed electrician, and must conform to
the National Electrical Code and comply with all the local codes and
regulations. Check with the local authorities before proceeding.
INSTALLATION NOTES:
Because of many different types of service, feeder and distribution
HTXLSPHQWQRVSHFL¿FZLULQJLQVWUXFWLRQVFDQEHSURYLGHG,WLV
recommended that only copper wire be used. In all cases it is
essential that while the load is connected to the generator, there can
be absolutely no feedback from the generator to the power line or the
power line to the generator. When properly installed, the normal ATS
Control and safety system will eliminate all paths and feedback.

which circuits will be on the emergency load circuit. If the entire load is
transferred, the transfer switch can be wired directly after the watt-hour
meter and the service entrance, providing the service entrance ampere
rating is within the transfer switch’s rated capability.

“emergency distribution panel” must be installed.
All selected emergency circuits are removed from main distribution
panels and installed in the emergency distribution panel. The ATS is
then installed between the main panel and the emergency distribution
