Mechanical Specifications

AVR can be mounted directly on the engine, genset, switchgear or control panel that conforms to the
mounting specification.

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.
