Warning notes
Only qualified personnel may open, interfere with or modify the actuators!
Read the actuator documentation carefully and completely. If not observed,
dangerous situations might occur.
Only qualified and authorized personnel may mount, set-up and maintain the
actuators
Risk of electric shock hazard – to disconnect from power, it may be necessary to
open more than one switch. Before performing maintenance work, the actuator
must be disconnected from power.
The electrical connection between the conduit fittings is not made automatically; it
must be established on installation site.
The connecting terminals must have adequate touch protection. Make certain that
non-insulated connections or wires cannot be touched.
Each time work is done (mounting, installation, service work, etc.), check to ensure
that the wiring is in an orderly state.
Fall or shock can adversely affect the safety functions. Such actuators must not
be put into operation even if they do not exhibit any damage.
Static charges must be avoided since they can damage the actuator’s electronic
components when touched.
Use of copper wiring is mandatory.
