Insulation
The user can change the value of the insulation resistance directly from the LCD display. The user must first
copy the TXT files to the SD card. These files can be requested from ZCS technical support.
Select “14. Insulation” and long press the key to enter the menu for setting the insulation resistance. The
display will show “Enter PWD!”; enter the password “0001” by short pressing the key to increase the
selected digit. Long press the key to move to the next one and confirm. If the display shows, “Error, try
again!” press the key again and enter the password again. When the password entered is correct, you can

If the setting is successful, “OK” will be displayed; otherwise, “Error” will be displayed.
Attention: do not enter this menu if the microSD card is not inserted in the appropriate slot of the inverter
or if the correct TXT files have not been copied to it.
