This instruction manual contains all the information regarding design, installation and start-up procedure for the electrical actuator unit type EA 41.
Warnings:
≠Do not work on this unit before disconnecting it from the mains!
≠The actuator is factory preset to a mains voltage of 230 V AC. By all means refer to Item 2.1.
≠Electric actuators do not have a safety position. In case of a mains breakdown, the actuator resp. the valve remains in its actual position.
≠Any work done on the actuator may only be carried out by authorized and trained personnel.
≠These products are according to the Machine Guidelines 98/37/EG (ancient 89/392/EWG), not regarded as machines; they are, however, built into installations which are regarded as machines.
Note
We distinctly emphasize that operation is prohibited until it has been confirmed that the machine (plant) into which the products have been built corresponds to the conditions of the EC Machine Guidelines 98/37/EG (ancient 89/392/EWG).

2.1 Mains Voltage Selection
230 V/50–60 Hz
The actuator is factory preset for 230 V
1@5 V/50–60 Hz
Selecting 1@5 V can be done by changing the corresponding jumpers as shown in the diagram
Do not work unit when under voltage!
