Disassembly
9.2 Disassembly
Although the disassembly of an actuator in principle proceeds in the reverse sequence to the
mounting, some essential points should be clarified before.
Will the actuator to be disassembled replaced immediately by another?
If not, in which position should the actuating element be following the disassembly?
Must the actuating element be fixed in its intended position?
If appropriate, does the production process of the plant need to be stopped?
Is it necessary to inform specific personnel about the disassembly?
9.2.1 Electrical disassembly
Using the actuator, rotate the actuating element into the intended position!
Switch off all the poles of the power supply and the controller of the actuator.
If necessary, set up warning signs in order to prevent:
• the inadvertent starting up of the part of the devices / machines / plant which is
affected by the disassembly, or
• the switching on of the power supply / the controller of the actuator.
Open the housing cover by loosening the screws and pulling the housing cover hard to remove it.
On this point , see chapter
6.2.1 „Removing the housing cover“.
Loosen the screws of the terminals and pull the leads out of the terminals.
Loosen the cable fittings and pull the cables out of the device.
Insulate the bare lead ends if the cables are not also being disassembled or are not to be imme-
diately reconnected to another actuator.
9.2.2 Mechanical disassembly
Loosen the four screws of the actuator and pull the actuator from the mounting position.
If appropriate, screw the housing cover back on. On this point, observe chapter
7.6 „Mounting of the housing cover“.
