Before you start
- Continuous overloading can cause high operating temperatures that could damage the set. Keep the load within the nameplate rating.
- Electrical shock can cause severe personal injury or death. Cord and plug equipment must have a ground terminal.
Procedure
- Note the rated output of the generator set from the nameplate or Specifications section.
- Check the load rating of each load; total wattage must not exceed the genset rated output.
- If a motor load and another load are close to rated output, start the motor load first and let it reach normal speed.
- Connect the AC loads to the receptacle(s) on the control panel.
- Make sure the cord and plug connector have ground terminals.
