ATTENTION
1. AVR can be mounted directly on the engine, genset, switchgear, control panel, or any position that will
not affect operation. For dimension reference, please see Figure 1.
2. All voltage readings are to be taken with an average-reading voltmeter Meggers and high-potential test
equipment must not be used. Use of such equipment could damage the AVR.
3. Terminal：“Fast-On” terminals 6.35 mm (1/4 inch).
4. Improper setting of under-frequency protection could cause the output voltage of the unit to drop or
become unstable under with changes in load. Avoid making any changes to the U/F setting unless
necessary.
5. Turn off O/E in AVR when paralleling.

ATTENTION
1. All AC voltage readings are average value only.
2. Use a remote 500 ohms 1 watt external VR for +/- 5% adjustment range. (keep shorted if not used)
3. Use a remote 1K ohm 1 watt external VR for +/- 10% adjustment range.
4. Sensing Voltage can be set from 220 – 600 Vac Program SW1-1 & 2 correctly.
5. For single phase sensing bridge E2 & E3 and move SW2-1 to OFF.
6. If your PMG is not working you can also power the AVR in shunt using terminals P1 & P2 connected to
the output of the generator as long as it’s less than 277 Vac.

※ Use only the replacement fuses specified in this user manual.
