–

Inverter with 1-phase line connection

Line connections:
Connect devices to the line voltage for 5 minutes.

Line voltage increase in stages.
The following graduations are recommended:

  • Stages 1, 2: AC 170 V for 15 minutes
  • Stage 3: AC 200 V for 15 minutes
  • Stage 4: AC 240 V for 1 hour
