the Mains Distribution Board 200PL1. In this case,
proceed as follows:
Check the states of the all the LEDs on the Mains
Distribution Board 200PL1(see

• If the states of any of the LEDs are abnormal, fix
• If the states of all the LEDs are normal, check with
a multimeter that the voltage between the X3 and
X4 connectors on the Inverter Board 300PL1 is at
415 V.
If the voltage is at 415 V, change the Inverter
Board 300PL1.
If the voltage is not at 415 V, check the cabling
