WARNING
Environmental Hazard. Always recycle batteries at an
official recycling center in accordance with all local
laws and regulations. Failure to do so could result in
environmental damage, death, or serious injury.
Always recycle batteries in accordance with local laws
and regulations. Contact your local solid waste collection
site or recycling facility to obtain information on local
recycling processes. For more information on battery
recycling, visit the Battery Council International website

•
Stationary generators installed with automatic
transfer switches will crank and start automatically
when NORMAL, UTILITY source voltage is
removed or is below an acceptable preset level. To
prevent automatic startup and possible injury to
personnel, do not connect battery cables until
NORMAL source voltage at transfer switch is cor-
rect and system is ready to be placed into opera-
tion.
•
When working on battery, only use tools with insu-
lated handles. Do not rest tools or metal parts on
top of battery.
•
Discharge static electricity from the body before
touching battery by first touching a grounded metal
surface.
•
Immediately wash down spilled electrolyte with an
acid neutralizing agent. Use a solution of 1 lb (500
g) bicarbonate of soda to 1 gal (4 L) of water. Add
the bicarbonate of soda solution until evidence of
reaction (foaming) has ceased. Flush resulting liq-
uid with water.
Battery Requirements
The ability to start the engine depends upon battery
capacity, ambient temperatures, and coolant and oil tem-
peratures. The engine/generator set data sheet lists mini-
mum recommended battery capacity at various ambient
temperatures. Recommended battery capacities are
listed under cold cranking amps (CCA) at 0 °F (−18 °C).
Battery capacities decrease as ambient temperatures
decrease, so it is important to specify batteries with the
appropriate CCA rating at a temperature no higher than
the minimum ambient temperature for the application.
Battery Installation
NOTE: Battery is not included with the 48 kW unit only.
Fill battery with correct electrolyte fluid as necessary and
have battery fully charged before installing it.
Use appropriate tools when working with battery termi-
nals. The use of terminal pullers, expansion pliers, and
terminal cleaning brushes will greatly extend the life of
the battery terminals.

over positive (+) battery terminal.
2. Grasp battery strap (B) and lift battery.
3. Set battery onto battery tray.
4. Tighten two screws with nylon washers to secure
hold-down clamp to battery tray, or fasten strap
(000228)
over top of battery.
5. Remove rubber protective cover from positive (+)
battery terminal.
6. Install positive battery cable (C) (red) on positive
(+) battery terminal.
7. Install negative battery cable (D) (black) on nega-
tive (-) battery terminal.
NOTE: The unit is equipped with a internal battery char-
ger. The internal battery charger is powered by the T1
wire. Verify power supply (T1 wire) has been safely dis-
connected before performing any work on the battery.

NOTE: At temperatures of 32 °F (0 °C) and below, it is
recommended that a pad type battery heater be installed
to aid in cold climate starting. This is available as a cold
weather kit through an IASD.
