Content    Nomenclature & system principle AC distribution DC distribution    Rectifier Monitor Maintenance & emergency handling Maintenance  Special Phenomena 1. With small output current, the rectifier’s fan may not rotate, or rotate very slowly. 2. With small load current, rectifiers may not share the load current equally. 3. The rectifiers may output only 52V due to limiting charge current though they are in equalizing charge state. 4. Alarm information will not be displayed if the alarm is disabled in Monitor PSM-A. 5. The system does not alarm though some of the fuses or circuit breakers are off. Handling Failure Procedure  Handling Failure Procedure 1. Make the system mute 2. Check and record the alarm indicators and information 3. Classify the failure ( of AC distribution, DC distribution, Rectifier or Monitor) 4. Analyze ( guess all of the possible causes) 5. Test and then locate the failure ( verify the guessing) 6. Handle ( caution: safety first, mark the plugs) 7. Confirm Emergency Handling   Principle: maintain the DC power for telecom equipment  Handling Emergency Cases 1. AC Distribution Failure 2. DC Distribution Failure • Load short circuit • Distribution short 1. Connect AC directly to rectifiers 2. Get rid of short • Cut off the fuse/breaker for the load • Cut off AC, then separate the battery from the system, and then power loads with battery or rectifiers directly 3. Monitor impacts DC 4. Rectifier failure • Inside short • Many rectifiers fail • Output over-voltage 3. Turn off monitor, manage battery manually 4. Turn off the failed rectifiers • Automatically turn off • Turn off, ensure enough normal rectifiers • Turn off all, then turn on one by one except the failed one.
