WARNING

Electric shock due to live components!

If the power supply is switched off, there is danger of electric shock due to live
components.

•

Prior to starting work ensure that the actuator is disconnected safely from the
mains power supply.

•

Secure against unauthorised switching-on.

The operating parameters are set

on the coding switches. The coding

switches are located under the printed circuit board cover

in the actuator

casing



4.4 Fit/remove cover



4.5.2 Remove printed circuit board cover

5.1

Operating parameters and coding switch positions

The operating parameters must be set with the coding switches before the linear
actuator can be operated.

ATTENTION

Malfunctions due to incorrect switch position S1

Switch S1 must always be at "on".

•

Ensure that switch S1 is at "on".
