ATTENTION
1. AVR can be mounted directly on the engine,
genset, switchgear, control panel, or any
position that will not affect 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. Secure all wiring connection. Do not install AVR
at a place with high vibrations to prevent loose
connections. For safety do not touch the heat
sink while in operation.
4. Terminal
：
“Fast-On” terminals 6.35mm (1/4 inch)
& With 4mm crimping terminal.
5. 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.
