This is used to broaden the input parameters to accommodate the voltage fluctuations created by
a backup generator or a noisy line. The factory default setting is normal, where the unit runs on
normal parameters. Switching to Generator makes it run on noisy generator parameters.
If the unit constantly switches between line and battery modes due to a noisy line, select generator
mode to prevent unnecessary transfers I returns. In generator mode, the acceptable range of input
frequency and voltage is expanded to accommodate the voltage and frequency fluctuations
created by a generator or a power source of such kind. Use a generator with electronic speed and
voltage controls which typically produces Total Harmonic Distortion in % (THD) of less than 10%.
Generators with mechanical governors can force the system to run continuously in Battery mode.
Before installation, compare the generator's output voltage to the UPS 's input voltage
requirements as listed on both nameplates. To insure the system's smooth operation, use a
generator capable of supplying 2X or twice as much power as required by the total load.
