Fuji inverter

[ex 2 Base]

I  have a Fuji inverter used to power a lathe. The invert has stopped working and the fault code OH2 is displayed, which says external thermal overload relay has tripped. I am unable to access the internal programme to reset the system. Any useful suggestion will be much appreciated.

External?
It sounds as though it thinks something has gone wrong with the Motor. Can you try another one?
