Electrical connection

230 V are applied to the mains 

voltage connections on the left side, 
L/ L’/ 1-5/ N. These terminals may only 
be touched when de-energized, since 
otherwise there is life-threatening 
danger due to electric shock. 

 

The terminal assignments 

depend on and vary depending on the 
selected hydraulic variant and option 
marked with " * ".

eBUS connection and sensor cables 
are to be installed so that they are 
physically separated from the high-
voltage lines.

Information regarding installation

 

• The strain relief (cable ties) can be 

mounted normally or reversed, 

depending on the used cable thick-

ness, in order to optimally secure the 

wiring.

 

• The electric installation and the pro-

tection have to comply with the local 

regulations. 

 

• The controller must be constantly 

connected to the power supply in 

order to ensure its function at all 

times.

 

• Upstream mains switches are there-

fore to be limited to emergency or 

main switches which are usually left 

in operation.

 

• Before set-up, it is to be checked 

whether all components are properly 

electrically connected.

 

 

Note

If there are strongly inductive loads near the controller (contactor, solenoid valves, etc.), sup-
pression might be necessary using RC elements directly at the coil connections of the dis-
turbing components. Recommended RC elements: 0.047
