F Frame construction
Required maintenance material (not included in the scope of delivery):
☐ A suitable water-free, heat-resistant lubricant
☐ Talcum, petroleum jelly or wax for maintaining the seals
DANGER
Danger to life due to electric shock or electric arc if live components are touched
• 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 25).
Procedure:
1. Check whether the seals in the sealing area show any damage.
If seals are damaged, contact us (see Section 9 "Contact", page 66).

6.4.2.7 Checking the Latches, Door Stops and Hinges
Required maintenance material (not included in the scope of delivery):
☐ A suitable, water-free and heat-resistant lubricant, e.g. WD40
☐ Non-greasing antifreeze agent, e.g. PS88
DANGER
Danger to life due to electric shock or electric arc if live components are touched
• Switch off the inverter and wait at least 15 minutes before opening it to allow the capacitors to discharge

• Disconnect the inverter (see Section 4, page 25).
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.
