OPERATING INSTRUCTIONS

Generator Operation

Be sure that the unit is properly grounded to an external ground path prior to operation. Refer to the section
entitled "Grounding" for proper grounding procedures.
SDR8CGW1, SDR8CGW3 AND SDR8CGW0: 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 8) 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.
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 8), 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 8) 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.
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.

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.
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
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.
