current is limited to 10 Amps at a voltage of up to 14/27
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 be flashing. The charging
voltage is held at 14/27 Volts and the charging rate
gradually reduces the amount of current (Amps) flowing to
the battery to 100% charged state. The battery can be left
on this mode indefinitely. During this mode, the green LED
will be on constantly.
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 with the United States
National Electric Code. It is suggested that this circuit be
fused for 15 amps.
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 equipment, no specific wiring instructions
can be provided. It is 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.
To wire the automatic transfer switch into existing wiring,
first determine 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.
If only specific circuits are to be powered under emergency
power failure conditions, an additional distribution panel
designated “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 panel.
Suggested circuits: freezer, refrigerator, furnace, emergency
lights, sump pump, emergency outlet circuits, etc. Total
running load must not exceed generator rating.
terminals and cable ends with dialectic grease.
WARNING
The electrolyte is diluted sulfuric acid that is harmful
to the skin and eyes. It is electrically conductive and
corrosive. The following precautions must always be
taken.
1. Always wear full eye protection and protective
clothing.
2. Where electrolyte contacts skin, wash off
immediately with water.
3. If electrolyte contacts the eyes, flush thoroughly
and immediately with water and seek immediate
medical
attention
4. Spilled electrolyte is to be washed down with an
acid neutralizing agent. A common practice is to
use a solution of one pound of bicarbonate of
soda
(baking soda) to one gallon of water. The
bicarbonate of soda solution is to be added until
the evidence of reaction (foaming) has ceased. The
resulting liquid is to be flushed with water and the
area
dried.
DANGER: EXPLOSIVE FIRE RISK
1. Never smoke when near batteries.
2. Do not cause a flame or spark in the battery area.
3. Always discharge static electricity from your body
before touching batteries by first touching a
ground metal surface.
SERVICING BATTERIES
Batteries used on these units may, over time, lose water.
This is especially true if you are using a trickle charger
to maintain your battery. Different types of batteries
require various types of maintenance. Refer to the battery
manufacturer for specific 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.

The block heater is thermostatically controlled and when
connected, will maintain the engine coolant temperature
between 100 and 120 degrees F.
A three-stage battery charger is provided standard on
this unit. The charger is an Automatic Battery Charger &
Maintainer. This charger has three rates of charging. During
the first mode, known as Bulk charging, the charging
