Disassembly
WARNING!
Unexpected movement of components.
Injury due to impacts or crushing.
•
Before working on the product, switch off the control and secure it to prevent
it from being switched back on accidentally.
CAUTION!
For vertical or slanted mounting position: when power is off, moving parts can
travel or fall uncontrolled into the lower end position.
Injury due to impacts or crushing.
•
Bring moving parts of the product into a safe end position or secure them
against falling.
1. Remove electrical installations with accessories.
2. Remove motor and mounting kit.
3. Remove the fastening components.
4. Observe transport information
