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 (116) on the coding switches. The coding
switches are located under the printed circuit board cover(33) in the actuator
casing (1).
