• Switch off the inverter and wait at least 15 minutes before opening it to allow the capacitors to discharge
completely.
• Disconnect the inverter (see Section 4, page 26).
Procedure:
1. Check whether the doors latch easily. Open and close the doors several times.
If the doors do not latch easily, lubricate all moving parts of the latch.
2. Check whether the stops hold the doors in place.
If the doors cannot be arrested, lubricate the door stops.
3. Check whether the door hinges move easily.
If the door hinges do not move easily, apply lubricant.
4. Lubricate all moving parts and movement points.
5. Tighten any loose screws with the appropriate torque.
6. If the inverter is installed in regions where below-freezing temperatures occur, apply the non-greasing antifreeze to
the profile cylinder of the door lock and the key switch in order to protect them from icing up.
