LOCATION
1.9.1 GENERATOR
Install the generator set, in its protective enclosure,
outdoors, where adequate cooling and ventilating air
is always available. Consider these factors:
• Install the unit where air inlet and outlet openings
will not become obstructed by leaves, grass, snow,
etc. If prevailing winds will cause blowing or drift-
ing, consider using windbreak to protect the unit.
• Install the generator on high ground where water
levels will not rise and endanger it.
• Allow sufficient room on all sides of the generator
for maintenance and servicing. A good rule is to
allow three feet of space on all sides.
• Where strong prevailing winds blow from one
direction, face the generator air inlet openings to
the prevailing winds.
• Install the generator as close as possible to the fuel
supply, to reduce the length of piping.
• Install the generator as close as possible to the
transfer switch. HOWEVER, REMEMBER THAT
LAWS OR CODES MAY REGULATE THE DIS-
TANCE.
• This genset must be installed on a level surface.
The base frame must be level within 1/2 inch all
around.

1.9.2 TRANSFER SWITCH
1.9.2.1 7 kW Unit
The transfer switch shipped with this generator is
enclosed in a NEMA 1 enclosure. This type of enclo-
sure is intended for indoor use only. Follow these
rules:
• Install the transfer switch indoors on a firm, stur-
dy supporting structure.
• To prevent switch distortion, level the switch if
necessary. This can be done by placing washers
between the switch enclosure and mounting sur-
face.
• Never install the switch where water or any corro-
sive substance might drip onto the enclosure.
• Protect the switch at all times against excessive
moisture, dust, dirt, lint, construction grit and cor-
rosive vapors.
1.10 BATTERY INSTALLATION
Fill the battery with the proper electrolyte fluid if nec-
essary 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.
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 connect-
ed. If the utility power supply is not turned off,
sparking can occur at the battery posts and
cause an explosion.
Battery cables were factory connected at the genera-
tor (Figure 1.4). Connect cables to battery posts as
follows:
3. Remove the 5A and 15A fuses from the generator
control panel.
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 (—).
Damage will result if battery connections are made
in reverse.
