If the failure doesn't last long, the battery will power the load. If the cause is unknown or the failure lasts too long, a diesel generator is needed. Before using generator power, run the generator for five minutes to minimize the impact on the power system.
How to troubleshoot DC Volt High on Vertiv Power Supply?
If the set value is inappropriate, correct the DC over-voltage value through the controller. To find out the faulty rectifier: 1. Ensure that the batteries can operate normally. 2. Switch off the AC input of all rectifiers. 3. Power on the rectifiers one by one. 4. If the over-voltage protection is triggered when a certain rectifier is powered on, that rectifier is the faulty one. Replace it.
What to do if Vertiv Power Supply displays DC Volt Low?
If the set value is inappropriate, correct the DC under-voltage value set through the controller. If the alarm is caused by mains failure, disconnect some loads to prolong the operation of the whole system. If any rectifier is inoperative or has no output current, replace it. If the total load current exceeds the total rectifier current during float charge, disconnect some loads or add more rectifiers to make the total rectifier current bigger than 120% of the total load current with one redundant rectifier.
How to fix Load Fuse Alarm or Batt Fuse Alarm on Vertiv Power Supply?
If the corresponding MCB is open, find out the fault and remove it. Otherwise, the alarm circuit is faulty. Please contact Vertiv.
What to do if Vertiv Power Supply Rect doesn't respond?
If the communication cable is properly connected between rectifier and controller, restart the rectifier. If the alarm persists, replace the rectifier.
How do I fix a Vertiv Power Supply when the Rect Fan Fails?
If the fan is obstructed, clean it and push the rectifier back. If the fan is not obstructed or if the fault persists after cleaning, replace the fan.
What should I do if my Vertiv Power Supply has a Rect Failure?
Power off the rectifier, and then power it on after a while. If the alarm persists, replace the rectifier.
How to resolve Batt Over Temp on Vertiv Power Supply?
If the battery compartment temperature is too high, cool down the battery compartment. If there is a battery internal fault, replace the faulty battery.
What does LVD2 mean on my Vertiv Power Supply?
Check if there is mains failure and the battery voltage is lower than the value of ‘LVD2’. Check whether the battery is disconnected from the system manually.
