Information Only replace fuses with fuses of the same type and value.
→ After replacing the fuses, screw local controls back on again.
Cable damage due to twisting or pinching!
Risk of functional failures.
→
Turn local controls by a maximum of 180°.
→
Carefully assemble local controls to avoid pinching the cables.
11.2.2. Motor protection (thermal monitoring)
In order to protect against overheating and impermissibly high surface temperatures
at the actuator, PTC thermistors or thermoswitches are embedded in the motor
