Disconnect the charging source prior to connecting or disconnecting battery terminals. Remove
the battery charger fuse (ATC style fuse, 5 amp on the 2.5 charger and 15 amp on the 10A charger).
•
Wear full eye protection and protective clothing.
•
Where electrolyte contacts the skin, wash it off immediately with water.
•
Where electrolyte contacts the eyes, flush thoroughly and immediately with water and seek medi-
cal attention.
•
Spilled electrolyte is to be washed down with an acid neutralizing agent. A common practice is to
use a solution of 1 pound (500 grams) bicarbonate of soda to 1 gallon (4 liters) of water. The bicar-
bonate of soda solution is to be added until the evidence of reaction (foaming) has ceased. The
resulting liquid is to be flushed with water.
!
Lead-acid batteries present a risk of fire because they generate hydrogen gas.
•
DO NOT SMOKE when near the battery.
•
DO NOT cause flame or spark in battery area.
•
Discharge static electricity from the body before touching the battery by first touching a grounded
metal surface.
*
Be sure the AUTO/OFF/MANUAL switch is set in the OFF position before connecting the battery
cables. If the switch is set to AUTO or MANUAL, the generator can crank and start as soon as the bat-
tery cables are connected.
$
Be sure the utility power supply to the battery charger is turned OFF and the 10A and 15A fuses are
removed from the generator control panel and the ATC style fuse removed from the battery charger,
or sparking may occur at the battery posts as the cables are attached and cause an explosion.
NOTE: A negative ground system is used. Battery connections are shown on the wiring diagrams. Make sure
the battery is correctly connected and terminals are tight. Observe battery polarity when connecting the bat-
tery to the generator set.
4.9.4— Battery Installation and Replacement
When required, the battery must be replaced with one of equivalent size, voltage, and CCA (cold crank amp capacity).
Consult the Unit Specification Sheet or contact the local Authorized Service Dealer for proper battery sizing.
A new battery must be filled with the proper electrolyte and be fully charged before installing.
Preliminary Instructions

4.
Battery cables are connected to the generator connection points at the factory. Connect the cables to the battery posts
as shown in Figure 4-2.
