BATTERY
Starting the unit requires 12-volt battery current. Use
two 6-volt (see SPECIFICATIONS) batteries for a
normal installation. Connect the batteries in series
(negative post of first battery to -positive post of
second) as in Figure 15. Necessary battery cables are
on unit. Service the batteries as necessary. Infrequent
unit use (as in emergency standby service) may allow
the batteries to self-discharge to the point where they
cannot start the unit. If installing an automatic
transfer switch that has no built-in charge circuit,
connect a separate trickle charger. Onan automatic
transfer switches include such a battery charging
circuit.

Do not smoke while servicing batteries. Lead

(32.2°C) such as in a boiler room. To
lengthen battery life, dilute the electrolyte from its
normal 1.275 specific gravity.reading at full charge to
a
1.2.25
reading. The cranking power is reduced
slightly when the electrolyte is so diluted, but if the
temperature is above 90°F (32.2°C), this should not
be noticed. The lengthened battery life will be worth
the effort.
1.
Fully charge the battery.
2.
With the battery still on charge, draw off the
electrolyte above the plates in each
cell.
DO NOT
ATTEMPT TO POUR OFF; use a hydrometer or
filler bulb and dispose of it in a safe manner. Avoid
skin or clothing contact with the electrolyte.
3. Refill each cell with distilled water, to normal
level.
4.

5. Test each
cell.
If the specific gravity is still above
1.255,
repeat steps 2, 3, and 4 until the reading is
reduced to
1.225.
Usually, repeating steps twice is
sufficient.
REMOTE
CONTROL
CONNECTIONS
Provision is made foraddition of remote starting. This
is accomplished on a 4 place terminal block situated
within the control box. Connect one or more remote
switches across remote terminal and B+ terminal as
shown in Figure 16. If the distance between the set
and remote station is less than 1000-feet (305 m), use
No.
18 AWG wire; between 1000- and 2000-feet
(305 m and 610 m), use No. 16 AWG wire,
