Error 00000004 on ACRP Unit

"

The 00000004 error on the ACRP cooling unit indicates that there is an Earth Fault on the output of the VFD. Normally this would indicate that there is an earth (ground) leakage from the output phases to earth, either in the cable between the frequency converter and the motor or in the motor itself. The fault will appear on the display of the DANFOSS VFD.  See IB0111GB01 for further information.  This can be viewed on the DRL (document reference library)
