CONTROL PANEL

A. 120 V, 20 Ampere Duplex Receptacle
This duplex is split so that 20 amps of current may be
drawn from each half of the receptacle. However, total power
drawn must be kept within nameplate ratings. These
receptacles may be used along with the twistlock receptacle
provided the generator is not overloaded.
B. 120/240 V, 30 Ampere Twistlock Receptacle
A maximum of 30 amps may be drawn from the 120/240
volt receptacle, provided it is the only receptacle used.
However, current must be limited to the nameplate rating. If the
120/240 volt receptacle is used along with the 120 volt
receptacle, the total load drawn must not exceed the nameplate
ratings.
C. Idle Control Switch
Some models are equipped with an idle control switch.
(See Idle Control).
D. Circuit Breakers
The receptacles are protected by an AC circuit breaker. If
the generator is overloaded or an external short circuit occurs,
the circuit breaker will trip. If this occurs, disconnect all
electrical loads and try to determine the cause of the problem
before attempting to use the generator again. If overloading
causes the circuit breaker to trip, reduce the load. NOTE:
Continuous tripping of the circuit breaker may cause
damage to generator or equipment. The circuit breaker may
be reset by pushing the button of the breaker.
E. Hour Meter
An hour meter is provided to keep track of run time of the
unit. This may be used to track maintenance schedules.
F. Voltmeter
Provides visual indication of generator output voltage from
0-300 volts.

G. Battery Charger
NOT RECOMMENDED FOR USE WITH GEL PACK,
SEALED OR SMALL (MOTORCYCLE) BATTERIES.
These generators contain an additional circuit used for
battery charging purposes. A double binding post is provided
on the control panel. The battery charger on this generator is
referred to as an unregulated taper charger - the most widely
used in the market today. The amount of current flowing will
depend on the charging voltage and battery's state of charge.
As the battery becomes more fully charged, the output current
to the battery decreases and nearly becomes constant. Taper
chargers are intended to be used with the provision that they
will be disconnected from the battery after a maximum time on
charge. Normally a period of 30 to 120 minutes is sufficient to
recharge a weak battery. The charge level of the battery
should be checked periodically.
CAUTION: This battery charging system is
intended to recharge weak batteries, not to
"boost start" vehicles. Do not overcharge
battery or leave battery unattended.
Note: When the battery charger circuit is in use, the AC
capacity is reduced by 180 watts. Make sure the combined
load is within the rated limits.
Before charging a storage battery, check the electrolyte
fluid level in all the cells. Add distilled water to each cell, if
necessary, to bring the level back up to the manufacturer's
required level.
WARNING: Storage batteries give off
EXPLOSIVE hydrogen gas while charging.
Do not allow smoking, open flames,sparks,
or spark producing equipment in the area
while charging.
Use cables approved for battery charging. Connect a red
clip to the positive terminal of the battery. Connect a black clip
to the negative terminal of the battery. Connect the other end
of the clip wire to the corresponding black(-) and red (+)binding
posts on the generator panel. After the battery is fully charged,
remove the battery charging cable from the generator and then
disconnect from the battery posts.
WARNING: Battery electrolyte fluid is
comprised of sulfuric acid that can be very
dangerous and cause severe burns. Do not
allow this fluid to contact eyes, skin, clothing,
etc. If contact or spillage does occur, flush
the area with water immediately.
WARNING: Do not continue to charge a
battery that becomes hot or is fully charged.
DC CIRCUIT BREAKER: The maximum current available
from the battery charger circuit is 15 amps. An automatic DC
circuit breaker has been provided to protect the circuit from
overloads and assure that the battery gets recharged. If an
overload occurs, the circuit breaker will trip. After it cools, it will
automatically reset itself. The battery's maximum rate of
charge will eventually reduce to less than 15 amps and then to
zero as the battery approaches a 100 percent state of charge.
