6.5.2 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-lubricating antifreeze agent (e.g. PS88)
Procedure:
2. Check that 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.
3. Check whether the doors are arrested.
If the doors are not arrested, lubricate the door stops.
4. Check whether the door hinges move easily.
If the door hinges do not move easily, lubricate them.
5. Lubricate all moving parts and movement points.
6. Tighten any loose screws with the corresponding torque.
7. 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 against freezing.
