What is the procedure to measure the insulation resistance of ATV71 drive.

Insulation resistor to earth:
The insulation resistor measurement is done at 500Vdc during 1mn between supply terminals “A”(All input / output terminals shorted) and D(earth).
The drive must be prepared (power terminals shorted L1,L2,L3,U,V,W,PO,PA,PC) and placed upon an isolated support.
The measurement is done between shorted groups “A” and “D”earth with a voltage of 500 Vdc.
A (Power terminals) and D (Earth)
(Standard -> 1Mohm minimum).
