Connect power source load conductors to clearly
marked transfer mechanism terminal lugs as fol-
lows
1. Connect UTILITY (NORMAL) power source cables
to switch terminals N1, N2.
2. Connect customer LOAD leads to switch termi-
nals T1, T2.
Conductors must be properly supported, of approved
insulative qualities, protected by approved conduit,
and of the correct wire gauge size in accordance with
applicable codes.
Be sure to maintain proper electrical clearance
between live metal parts and grounded metal. Allow
at least 1/2 inch for 100-400 amp circuits.

BATTERY INSTALLATION
DANGER
Do not dispose of the battery in a fire. The
battery is capable of exploding.
A battery presents a risk of electrical shock
and high short circuit current. The following pre-
cautions are to be observed when working on
batteries:
• Remove watches, rings or other metal objects;
• Use tools with insulated handles;
• Wear rubber gloves and boots;
• Do not lay tools or metal parts on top of the
battery; and
• Disconnect charging source prior to connecting or
disconnecting battery terminals.
Do not open or mutilate the battery. Released
electrolyte has been known to be harmful to the
skin and eyes, and to be toxic.
The electrolyte is a dilute sulfuric acid that is
harmful to the skin and eyes. It is electrically
conductive and corrosive.
The following procedures are to be observed:
• Wear full eye protection and protective clothing;
• Where electrolyte contacts the skin, wash it off
immediately with water;
• Where electrolyte contacts the eyes, immediately
flush thoroughly with water and seek medical
attention; and
• 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) or 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 and the
area dried.
Section 2 — Installation
Air-cooled 15 kW Generators
Lead-acid batteries present a risk of fire because
they generate hydrogen gas. The
following procedures are to be followed:
• DO NOT SMOKE when near the battery;
• DO NOT cause flame or spark in battery area; and
• Discharge static electricity from body before touch-
ing the battery by first touching a grounded metal
surface.
Be sure the AUTO/OFF/MANUAL switch is set to
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
battery cables are connected.
Be sure the utility power supply is turned off, or
sparking may occur at the battery posts as the
cables are attached and cause an explosion.
Fill the battery with the proper electrolyte fluid if
necessary and have the battery fully charged before
installing it.
Before installing and connecting the battery, complete
the following steps:
1. Set the generator's AUTO/OFF/MANUAL switch to
OFF .
2. Turn off utility power supply to the transfer
switch.
3. Remove the 5 amp fuse from the generator con-
trol panel.
If the AUTO/OFF/MANUAL switch is not set to its
OFF position, the generator can crank and start
as soon as the battery cables are connected. If
the utility power supply is not turned off, spark-
ing can occur at the battery posts and cause an
explosion.
Battery cables were factory connected at the genera-
tor (Figure 2.4). Connect cables to battery posts as
follows:
4. Connect the red battery cable (from starter con-
tactor) to the battery post indicated by a positive,
POS or (+).
5. Connect the black battery cable (from frame
ground) to the battery post indicated by a nega-
tive, NEG or (—).
6. Replace the 5 amp fuse in the generator control
panel.
Damage will result if battery connections are made
in reverse.
