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. 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. 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, Weight: 2.2487150724 pounds, Manufacturer: Ynusgeyx
