VPRS-430 OPERATION MANUAL 27 /30
The purpose of this document is to provide guidelines to test the system, setup
measures to restore the system within a shortest possible time when any fault
occurs to the system. In addition, this manual enables to restore any problem in
the system in a short time to normal state. Enough amounts of spare parts must
be prepared to repair fault units. Even though the fault location and reason are
detected under the guidelines of this Manual, if field repair work is not possible, or
long period of time is needed for repair, the fault units should be replaced with
spare ones reserved. Then, the fault units can be repaired with enough amount of
time.
Note : As this rectifier uses AC voltage, it may cause electric shock. As battery
voltage is fed to the system, safety measures should be taken to repair and
maintain the system. As the battery generate a large amount of DC current,
worker should take off watch, ring or other metallic accessories.
