ATTENTION 

1. Before  using  a  Megger  or  a  Withstand  Voltage  Tester,  removes  the  wires  connecting  to  the  AVR  to 

prevent high voltage damage to the regulator. 

2. 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.

 

  Use only replacement fuses specified in this user manual. 

  Appearance and specifications of products are subject to change for improvement without prior notice.
