BATTERY
CONNECTION
Battery requires negative ground. Do
not
attempt to change
battery polarity on these
sets.
Refer to
set
wiring diagram.
~
If
the battery
is
connected
to
the charging
~
circuit with the
wrong
polarity, damage
will occur
after three minutes while stopped or
in
five
seconds while running. Alternator windings will be
damag-
ed almost instantly
if
battery charging circuit
is
.shorted
before the resistor.
Refer
to
set nameplate for battery voltage. For
AC
plants with
12
volt system, provide two 6 volt batteries
connected in
series
(one battery's negative
to
the other
battery's positive, Figure 9)
for
105
amp-hr,
12
volt source.
For
AC
pla:nts with
32
volt system, provide
32
volt
set
of
batteries and 200 ampere fused switch,
see
wiring diagram
for
connections.
Connect the battery positive (+)
to
the starter engaging
solenoid terminal post. Connect
t.he
battery nega-
tive
(-)
to
a
good
ground on the engine. (Figure 9).
WATER
SUPPLY
L!NE
(FIGURE
8)
A continuous supply
of
cooling water
is
required. The
water
pump
inlet
is
1/4" pipe thread to
1/2"
hose coupling.
Use a section of flexible hose near the
set
to
absorb
vibrations. The inside diameter of the plumbing must
be
1/2"
or larger. Use permatex
or
other pipe
sealer
on
all
pipe fittings in supply line
to
pump.
Normally, the
pump
should deliver 6 gallons
of
cooling water per minute.
Measure the discharged water flow after thermostat opens,
to
assure
the supply line
is
h~rge
enough. Reduce
resistance
on
pipe runs longer than 5-ft.
by
using larger inside dia-
meter plumbing.
To
prove suction line is air
tight,see
that
no
bubbles appear in discharged water.
An
air leak reduces
lubrication and shortens life of
pu
mps
impeller.
Install
a
strainer
in
the
water suction line inlet and where
accessible
for cleaning.

(OPTIONAL)
For Ie mote control starting and stopping, use 3 wires to
connect the remote switch (SPDT,momentary contact, center-
off type)
to
the terminal block marked B+,

box
using wire

as
listed
in Figure 9. Pre-

The
set
nameplate shows
the
electrical output rating of the
set in watt
s,
volts and hertz.
The
set
wiring diagram shows
the electrical circuits
and
connections necessary for the
for the available ootput voltage. Also
see
Figure 12.
Meet
all applicable
electrical
code requirements.
Work
should be done
by
a qualified serviceman or electrician
because the installation will be inspected and approved.
The
set control box (junction box)
has
knockout
sections
to accommodate load wires. Use flexible
~onduit
and
stranded load wires near
the
set
to
absorb vibration. Use
sufficiently large insulated wires. Strip insulation
from
wire ends
as
necessary
for
clean connections. Connect
each load wire to the proper generator output lead inside
the set control box. Insulate bare ends
of
ungrounded
wires. Use a bolt (through
the
control box) to connect
the grounded (-:;:-) generator
lead and load wire.
Install
a fused main switch
(or
circuit breaker) between the gen-
erating
set
and load (Figure 11).
If
a test run indicates
wrong
rotation
of
3 phase motors
in
the load circuit, switch
the connections
at
any
two
generator terminals.
