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.

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.
