Problem Description:
Drive tripped on alarm code 12816
 

Repair Actions:

A step down transformer may be required

Comments:

Alarm code 12816 is triggered by mains overvoltage. Measured mains voltage is 452Vac which is close to the upper limit of 460Vac for the Neos Drive. This was measured when the compressor was running. Most probably the mains voltage will increase even more when the compressor is stopped.
