BATTERY
CONNECTION
Battery
requires negative ground. Do not attempt to
change
batteiy
polarity
on
these
sets.
Refer to set
wiring
diagram.
CAUTION
11
the
battery
is
connected
to the
charging
circuit with
the
wrong polarity, damage
will occur alter three minutes while stopped
or in
live
seconds while running. Alternator windings will
be
damag-
ed almost instantly
il
battery charging circuit
is
shorted
belore
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 plants
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 the fcattery
nega-
tive
(-)
to a good ground on the engine. (Figure 9).
WATER
SUPPLY
LINE
(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 large 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 pumps impeller.
Install
a
strainer in the water suction
line
inlet
and where accessible
for
cleaning.
REMOTE
START
-
STOP
SWITCH
(OPTIONAL)
For
re 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+, 1, 2, 3, in the
set
control
box using
wire
sizes
as
listed
in Figure 9. Pre-
heat
circuit
requires an extra
wire
to terminal H and
momentary contact
switch
(SPST) connection. Remove
jumper
between terminals 3 and H before
installing
remote
wiring.
LOAD
WIRE
CONNECTIONS
(AC)
The set nameplate shows the electrical output rating of the
set in watts, volts and hertz. The set
wiring
diagram shows
the electrical circuits and connections
necessary
for the
for
the available output 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 knock out sections
to
accommodate load wires. Use
flexible
conduit 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 (-i-) 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.
Balance
.
All
Loads: Cunent for any one output load must
not
exceed nameplate
rating.
Overloading can
damage
the generator windings.
Divide
the loads equally between
output
leads.
Single
Phase
Loads
on
Three
Phase
Generators:
Any
combination
of single
phase
and three
phase
loading can
be used at the
same
time as
long
as the current for any
one output lead
does
not exceed the generator nameplate
rating.
