Generator Operation

GR3100, GR3200 AND GR3300: THE CURRENT RANGE
SELECTOR SWITCH (LOCATED AT THE TOP RIGHT OF
THE ALTERNATOR CONTROL PANEL) MUST BE SET TO
"180/200 - GEN" (FAR RIGHT POSITION) FOR 120VAC &
240VAC OPERATION.
1. All load devices and extension cords should use three prong
terminals. Refer to Table 2 (page 11) for extension cord and
cable size requirements.
2. Allow the engine to run for 2-3 minutes before applying any
electrical loads.
3. The 120 volt duplex receptacles are rated for 20 amps and
may be used in any combination of 120 volt loads and also
with 240 volt loads through the 240 volt receptacles.
All receptacles are part of a circuit protected by a Ground
Fault Circuit Interupter (GFCI). Ground Fault Circuit
Interrupters can significantly reduce the possibility of injury
if an electrical short occurs. The engine must be running
and the front panel switches set to supply power to the
receptacles before the GFCI can be reset.
A Ground Fault Circuit Interrupter may not be
effective if the unit is not grounded! Refer to the
section entitled Grounding for proper steps to ground the unit.
The 120 / 240 volt twist lock receptacle is rated for 30 amps
and may be used in any combination of 120 volt and 240
volt loads.
4. Individual receptacles should not be loaded beyond the
amperage rating.
5. Total combined load through any combination of
receptacles must not exceed the rated load limits of the
unit. Refer to the identification plate on the unit for amp
and wattage specifications.
6. Always shut off and remove loads before starting or shutting
off the engine.
7. When plugging multiple electrical load devices into the
receptacles, be sure to connect and activate the highest
power draw item first. Allow the engine to stabilize, then
connect and activate the next highest power draw device.
The smallest power draw device should be connected to the
receptacle and activated last.
NOTE: Power draw can be calculated by multiplying volts and
amps. The resulting number is wattage.
Never exceed the posted maximum wattage for the unit or any
individual receptacle. Refer to owner's manuals and product
tags to determine the wattage of all electrical load devices.
If actual watt ratings are not available, the Power Usage Chart,
see Table 1 (page 11), may be used as a general guideline.

Remember that devices which generate heat during operation
such as heaters, incandescent light bulbs, motors and hair
dryers have a higher power draw than devices which generate
little heat during operation such as florescent bulbs, radios, and
clocks.
Long power cords and extension cords also draw additional
power. Keep cords at minimum possible length.
Refer to Table 2 (page 11) for maximum limits for lengths of
extension cords.
8. Circuit protection is provided by circuit breakers. The main
circuit breaker is a rocker type rated for 30 amps. This
is the maximum total current draw for all receptacles in
combination. A 20 amp circuit breaker supplies each of the
two duplex receptacles. The circuit breaker opens when
the load exceeds its maximum capacity or a short circuit
occurs. If the circuit breaker opens, perform the following
procedures to correct the problem:
a. Shut off and disconnect all electrical loads.
b. Attempt to determine the cause of the electrical
problem - overloading or short circuit.
c. Do not use any devices that have short circuits.
Avoid overloading the unit.
d. Press the circuit breaker pushbutton or rocker to reset
the circuit breaker.
Repeated cycling of the circuit breaker indicates
a problem and may cause damage to the unit or
load devices. Do not operate the unit if repeated cycling of the circuit
breaker occurs.
INSTALLATION FOR STAND-BY USE
Precautions must be taken to prevent electrical back feeding
into utility systems. This requires isolation of the electrical
system. To isolate the electrical system, perform the following
procedures:
1. Turn off the main electrical system switch prior to
connecting the unit.
2. In accordance with national and local standards, a double
throw transfer switch must be installed in the system.
Always shut off main power prior to temporary
connection of the unit to a building electrical
system.
Installation of the unit as a backup electrical
source must be performed by a qualified
(licensed or certified) electrical technician.
