Issue
PM5500 meter shows an error message on the front display "Internal Power Supply Failure". The meter is unresponsive and communications cannot be established.

Product Line
PM5500

Environment
Power and Energy Monitoring

Cause
The meter will randomly display an error message stating "Internal Power Supply Failure". The message may disappear momentarily if the device is power cycled.

Resolution
If the firmware is below revision 1.00.0004, it will need to be upgraded. This upgrade will provide a more reliable display of the power supply failure message and recovery.

NOTE: DLF-3000 is required to update to firmware version 1.01.0000 and earlier. The DLF-3000 application and installation instructions can be found at the following link:
