If any error on the rectifier system is not solved under the direction of above Table 3-1,
contact a Sales Representative or the headquarters of Dongahelecomm.
5.2 Rectifier Removal / Replacement
①
The Rectifier Modules are hot-swappable so can be replaced with AC power applied.
(Note that if any external battery has been connected, the Control Unit still operates.)
②
The Control Umnit is not hot-swappable so replacement requires that the AC input
voltage be turned off and all external batteries be disconnected (BATT circuit
breakers OFF). Then the Control Unit can be replaced and the system power
restored.
5.3 Rectifier Module Restart
If a Rectifier Module output voltage is suspended due to a DC OverVoltage (OV) or
Fan Failure (FF), manually turn off the main AC Circuit Breaker. Then, when the
module is fully discharged (LED off), turn on the AC Circuit Breaker to see if the
event was isolated or recurring. If the OV/FF is still indicating the failure, replace the
Rectifier Module and repeat this restart process to check thast the replacement
module clears the alarm.
6 - Rectifier Maintenance
6.1 Overview
The purpose of this document is to provide guidelines to test the rectifier and setup
measures to restore the rectifier to normal operation within a shortest possible time
when any fault occurs to the system. Enough field-replaceable spare parts must be
maintained on-hand to prepare for replacement of units or components that may fail in
the field. Even though the fault location and reason are detected under the guidelines of
this Manual, if field repair work is not possible, or a ong period of time is needed for
repair, the faulty units should be replaced with a spare one held in reserve. This allows
