OPERATION
PARALLEL OPERATION
See Figure 20.
Parallel operation gives you the ability to link two compatible
Westinghouse inverter generators for combined running and
peak power output.
DANGER
Never connect or disconnect the parallel cable leads
when a generator is running. Failure to follow this rule
may lead to serious personal injury or death.
WARNING
and right cables is very important, especially when the
generators are used with a transfer switch to supply
power to a building. To avoid serious personal injury
or damage to electrical devices, including the genera-
tors, do not try to power an electrical system in a build-
ing without using an approved transfer switch.
NOTICE
Connecting to a generator that is
not compatible can cause a low voltage output that
may damage tools and appliances powered by the
generator.
Use only the Westinghouse 120/240V parallel cable that
came with your generator. Third party cables may not have
the ability to carry the increased voltage. If damage or loss
occurs to your cables, call Westinghouse customer service
for replacement.
The parallel cables and parallel ports are color-coded. There
is a third wire that carries the ground. Use the following
steps to connect the two generators.
NOTE: Be sure both generators have been shut down and
there are no devices connected to the outlet receptacles.
To install the parallel cable:
l Insert the cable ends of the same color into the matching
color parallel ports on the unit.
l Loosen and remove the ground terminal nut.
l Connect the ground wire to the terminal and reinstall the
ground terminal nut. Tighten securely.
Start one generator at a time. Wait for the first unit to run
at a stable idle before starting the second unit. Connect
one device at a time and allow the unit to stabilize before
connecting the next device.
To remove the parallel cable:
l Remove all devices from the generator's receptacles.
l Shut down both of the connected generators.
l Remove the parallel cable ends from the generator ports.
l Remove the ground terminal nut and ground wire. Be
sure to replace and tighten the ground terminal nut.
Fire and electrocution hazard.

LOW OIL INDICATOR
See Figure 20.
The LOW OIL LED on the control panel will illuminate when
the unit is low or out of oil. The generator will not start when
the indicator is lit. To resume normal operation, add engine
oil as described earlier in this section. Do not attempt to
crank or start engine before it has been properly ser-
viced with recommended oil.
ECO MODE
See Figure 20.
NOTICE
Always start the generator with the
ECO mode switch in the OFF position. Allow the en-
gine speed to stabilize and the OUTPUT READY LED
to illuminate before putting the ECO mode switch in
the ON position.
NOTICE
Do not use ECO mode when in parallel
operation with another Westinghouse inverter gener-
ator.
ECO mode minimizes fuel consumption and noise by ad-
justing the engine RPM to the minimum required for the
current load.
Turn ECO mode ON when powering small appliances with
continuous loads such as a computer or electric light.
Turn ECO mode OFF when powering large surge loads
such as an air conditioner or electric pump.
To turn on ECO mode, verify that the OUTPUT READY LED
is illuminated, then push the switch to the ON position. If no
load is present, the generator RPM will drop to idle speed.
The generator will detect loads as they are applied and
increase engine RPM.
To run the generator at maximum power and RPM, push
the ECO mode switch to the OFF position.
OVERLOAD RESET
See Figure 20.
Do not overload the generator. If the generator is ap-
proaching or has reached an overload condition, the OVER-
LOAD LED on the control panel will illuminate.
If the generator is close to overloading, the OVERLOAD
LED will blink. Turn off and remove one or more connected
devices to decrease the load and resume normal operation.
If the load is not reduced, the unit will reach an overload
condition. To extend the service life of the generator, avoid
running the unit near capacity.
If the generator is overloaded or if there is a short circuit in
a connected device, the OVERLOAD LED will turn solid,
and the unit will automatically disconnect from the load.
The engine will continue to run, but there will not be any
electrical output.
