Battery Installation

Operating Instructions

The KOHLER 20RESCL-200SELS generator system is designed for automatic operation, providing seamless power transfer during utility outages.

Automatic Operation

  • When utility power is interrupted, the automatic transfer switch (ATS) detects the outage.
  • The ATS signals the generator to start.
  • Once the generator reaches proper voltage and frequency, the ATS transfers the electrical load from the utility to the generator, typically within 10 seconds.
  • When utility power is restored, the ATS transfers the load back to the utility and signals the generator to cool down and shut off.

Manual Operation (For Testing/Maintenance)

Refer to the generator's control panel manual for specific instructions on initiating manual start/stop procedures for testing or maintenance purposes. Always ensure the generator is in a safe operating state before manual intervention.

Maintenance

Regular maintenance is crucial for the longevity and reliable performance of your KOHLER standby generator. Adhere to the maintenance schedule outlined in the comprehensive owner's manual.

Routine Checks

  • Weekly Exercise: The generator is programmed to run a short exercise cycle weekly to ensure readiness. Verify this cycle occurs.
  • Visual Inspection: Periodically inspect the generator for any visible damage, leaks, or obstructions around the air intake and exhaust.
  • Enclosure: The 100% corrosion-proof enclosure should be kept clean and free of debris to maintain proper ventilation and appearance.
