CONTROL PANEL FUNCTIONS
WARNING!
WARNING!
Never connect generators that are different models.
Generator must be properly grounded to prevent electrocution.
• Only connect this generator to another PMG4000iSR Standard Generator.
• Only use a parallel operation cable kit designed to work with this Generator
The generator’s ground terminal must always be used to connect the generator
to a driven ground rod. Connect the ground terminal to the driven ground rod
with a 12 AWG (American Wire Gage) copper wire. The wire connects to the
terminal between the lock washer and nut. Tighten the nut securely to ensure
good connection. Grounding the generator protects you from electric shock
that results from a build up of static electricity or undetected ground faults.
Turn counterclockwise to remove the fuel tank cap.
Located just above the Ground Terminal, the generator’s Parallel Outlets enable a user to run two
PMG4000iSR generator’s simultaneously. This operation requires special cables. When operating parallel
generators, the rated output is 7.0kVA and the rated current is 58.3A/120VAC. For cables and instructions
consult a PowerMax dealer for a PARALLEL OPERATION CABLE KIT.
Note: The Economy switch must be turned to the “OFF” position when using electronic devices that require
a large starting current, such as a compressor.
• Only operate generator on a level surface.
• Always connect the nut and ground terminal on the frame to an appropriate ground source.

OPERATION
AC Parallel Operation
It is possible to connect two PMG4000iSR generators to each other, using a parallel cable kit, to increase
available power output.
• Connect PARALLEL OPERATION CABLES to two PMG4000iSR generators according to the
instructions
provided with the cable kit.
• Make sure the Economy switch is in the same position on both generators.
• All electronic devices should be turned “OFF” and disconnected from generators prior to starting
generator engines.
• Start generator engines. Make sure the green output indicator light comes on for each generator.
• When engines have stabilized, plug in electronic device to AC receptacle and turn on first load.
• Allow generator output to stabilize (engine and attached devices run evenly) before plugging in the next
load.
Limit operation time to 3 seconds for load requiring Maximum
output. For continuous operation, do not exceed tbe rated output.
Note: It is strongly recommended to plug in devices with the
largest output first and the smallest output last to help prevent
overloading the generator.
Note: Most electronic devices require power beyond its rated wattage to start. This additional power
is referred to as surge watts and usually lasts between 2-3 seconds. When an electronic device is
started, the red overload indicator may come on. This is normal. If the light stays on disconnect all
electronic devices and stop the engine. Refer to “Engine Overload Indicator Light” on page 8.
WARNING!
WARNING!
Only connect electronic devices to the generator that are in good working
order and do not exceed the rated power supply of the parallel generators or
the desired receptacle.

• A faulty appliance or power cord can create an electric shock. Do not use electronic devices that have a
damaged cord or plug.
• If an appliance begins to operate abnormally, becomes sluggish, or stalls, turn off and disconnect appliance
immediately. The appliance may have a fault or its rated load capacity exceeds the power supply of the
generator.
• To avoid damage to generator or electronic device, do not connect a load to the generator if its electrical
rating exceeds
• Only connect this generator to another PMG4000iSR generator.
• Only use a PowerMax approved parallel operation cable kit to connect generators.
