G11-124 (Load Shed Ki t for RXT/RDT) 6/13
Operation
D Loads are automatically added or disconnected based on generator capacity.
D The Kohler-patented load control system uses dynamic logic to prevent shedding important loads unnecessarily when air
conditioning, refrigerator, or water pump motors start.
D The load shed kit and generator communicate to provide smart power management. The time to shed loads decreases as each
load is shed to quickly adapt to critical power requirements.
D Load shed power level and frequency setpoint adjustments are possible only by using Kohlerr SiteTecht software, available to
Kohler-authorized distributors and dealers.
