For 60 Hz systems, the regulator is preset at 55 Hz. For 50 Hz systems, connect a jumper across terminals Hz 1 and Hz 2. The corner frequency can be adjusted using the U/F ADJ rheostat.
Decrease the input voltage to less than 6 Vac for a minimum of 2 seconds, which can be done by stopping the prime mover or interrupting the regulator input with a reset switch.
Voltage regulation should be better than +/- 1.0% no-load to full-load.
