3. 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. 2. 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, & ZZ output, but sensing is always at 240V from T7 and T9 even though the generator is running sometimes at 480/277V. 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. 4. Improper setting of under-frequency protection could cause the output voltage of the un, Manufacturer: Mcnhbdgg
