Orientation

 Installation must be carried out in compliance with local installation regulations.

Notes on ele

ctrical

installation



The cable must be connected downwards so that it leads away from the bottom.

 If fluorescent lamps are used, separate load circuits are required to provide

protection against overvoltage.

 Magnets can damage the actuator.

 A means of isolation from the power supply must be provided, for example by

connecting an automatic circuit breaker or switch fuse upstream of the control unit.

Maintenance

STS61.. actuators are maintenance-free.

Repair

Faulty actuators must be replaced as complete units. The actuator will be destroyed

when opened. Exchange of the connecting cable is not permitted.

Disposal

The device contains electrical and electronic components and must not be disposed of

as domestic waste. This applies in particular to the PCB.

Legislation may demand special handling of certain components, or it may be sensible

from an ecological point of view.

Current local legislation must be observed.
