Safety notes
- 6 -
Maintenance and repair work may only be performed by qualified personnel. When wiring
electricalequipmenttheapplicableVDEandEVUregulationsareobserved.
Electricalprotectionmeasures(groundingresistance,etc.)aretobechecked.
Whenworkingontheactuatororconnectedtothesedevicesandsystemcomponents,thesupply

Perform the installation, repair work in compliance with the applicable statutory and professional
safetyandaccidentpreventionregulations!
The safety aspects are always depending on the circumstances and the timing of the assembly,
disassembly,adjustment,commissioningandarethereforealwaystoadapttotheapplication.
Mounting
These safety instructions are to be considered by any person concerned with the operation,
maintenance or repair of the actuators. The proper and safe operation requires proper
transport,properstorage,mountingandcarefuloperation.

Switch from AUTO to MAN, move the handwheel/ handlever to synchronize the
transmission then exit the adjustment path manually and turn back to the starting
position. Then switch from MAN to AUTO and move the handlever/ hand wheel

disconnect the equipment, machinery, plant, where appropriate, from the net!
Check whether the plant shut-down causes potential danger ! Inform the shift foreman, safety
engineer or the conductor immediately to prevent a fault in the actuator, by run out or spilling of
liquidsorleakageofgases,withsuitablemeasures!
Check the correct function of the safety devices (e.g. Emergency-Stop-Switch/Safety valves
etc.)!
Provideforadequatevibrationisolation!Vibrationscancausedamagedependingonthetypeor
resonance with the actuator components. Be particularly sensitive to wearing parts such as
potentiometers,motors or electronic components.Theuseinvibration-prone environmentshas

When installed in wet environments and in areas with significant temperature changes in each
case the built-in control room heater has to be kept actively after the actuator is stopping in the
endposition.
Fireplaces, stoves, direct sunlight and other heat sources can emit large amounts of energy.
