ATTENTION
1. AVR can be mounted directly on the
engine, genset, switchgear, control panel,
or any position that will not affects
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 6.35mm (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.
