“Extern OFF” connection: Remote deactivation
CAUTION
Property damage due to external voltage!
An external voltage which is applied destroys the component.
- Do not apply external voltage (connect potential-free).
Remote deactivation of all pumps can be performed using a separate switch:
- Contact closed: pumps enabled
- Contact open: all pumps deactivated – the display shows the “Extern OFF” symbol.
The terminals are fitted with a converter bridge at the factory.
Insert the connection cables laid by the customer through the threaded cable glands and secure. Remove the converter bridge and connect the wires to the terminal strip according to the connection diagram. Use the terminal number shown in the connection overview on the cover.
