ADVR-054
WARNING
1. Some generators even when working at high voltage are factory set to sense at lower voltages.
Remember to set the DIP SW 2 to the sensing voltage not the working voltage of the generator even do
sometimes it can be the same. If you have a 480/277V generator but you have the sensing wires C and A
connected to 240 Volts move DIP SW 2 to ON
Another example are rental units with multi-voltage output with a switches for Y, YY, Delta & ZZ output,
but sensing is always at 240V from T7 and T9 even though the generator is running sometimes at
480/277V.
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. 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.
