Issue
Current or voltage connections may be wired Incorrectly on a PM5000 series meters and it may be desired to correct this without rewiring the physical connections through register writes.

Product Line
PM5100, PM5300, and PM5500 Series Meters

Environment
Metering inputs and the register list of PM5000 series meters

Cause
Current and voltage connections wired incorrectly.

Resolution
At this time (November 2024) there is not a "soft" way to swap the polarity on a PM5000 series meter via register writes or other setup parameters. The PM5500 series meter does not support the swapping the CT polarity using modbus command. Therefore, the user is required to make physical changes to the meter itself.
