USING YOUR GENERATOR
CONNECTING ELECTRICAL DEVICES
1. Before connecting electrical devices, allow the generator to run for a few minutes to stabilize the speed and
voltage output.
2. Select the device with the highest wattage, and make sure it is turned off. Plug the device into the matching
generator outlet and then turn the device on. Allow the engine to stabilize.
3. Repeat step 2 to plug in each additional device. Do not attempt to plug in or start multiple devices at the same
time.
ECO-MODE SWITCH
This generator is equipped with an Eco-Mode Idle Control Switch (page 12). Engaging this switch allows the
system to regulate the engine speed and automatically adjust its fuel consumption to match the required load.
When the electrical load changes, the generator engine will automatically speed up and slow down as needed. This
reduces fuel consumption and noise levels, while extending runtime and engine’s lifespan.
Keep this switch engaged ONLY when the power load requirement is less than 2400W (75% of the rated watts). Do
not engage the Eco-Mode Switch when the total load is more than 2400W. The generator engine must run at full
speed to supply power for anything over 2400W.
PARALLEL OPERATION
The parallel connection ports (page 12) allow you to connect two WEN generators to increase the total available
electrical power. The WEN Parallel Connection Kit can be purchased from
wenproducts.com.
Follow the instruc-
tions included with your parallel connection kit for proper installation and operation.
CIRCUIT BREAKER
The 20A AC circuit breaker will activate when the load on the NEMA 5-20R outlets exceeds 20A. When the circuit
breaker activates, turn off and disconnect the device from its respective outlet, and press the circuit breaker to
reset.
IN CASE OF OVERLOAD
If your generator becomes overloaded from too much drawn wattage, the overload light (red) on the control panel
will light up. Follow the instructions below when an overload occurs:
• When you’re close to overloading the generator, the overload light will start to flash. Reduce the load by turn-
ing off and disconnecting your electronic device(s) until the overload light turns off. Then you may continue to
operate your generator.
• When you’ve overloaded the generator, the overload light will stay on and the overload reset button (page
12) will activate to cut off the output in 3 to 16 seconds, depending on the load. Reduce the load by turning
off and disconnecting your electrical device(s) until the overload light turns off. Wait about five minutes and
then press the activated reset button to reset the circuit. If no power is produced after resetting, turn off and
disconnect all electrical devices and restart your generator.
