Wiring diagram for BE24, BLE24, BE230 and BLE230 actuators
Notice:
Controlling the operation of BE and BLE actuators requires connecting them to an electrical wiring system using
three-wire cables. The change of rotation direction is effected by applying supply voltage to terminal 2 or 3,
depending on the desired direction of rotation.
The position of limit switches for all actuator types applies to a potential free position.

Wiring diagram for EXBF actuators
Several actuators may be
connected in parallel. Power
consumption should be
monitored.
Notice: 24 V connection
through a safety
transformer.
To disconnect the BE230 and BLE230 actuators from
the electrical wiring system (mains), a breaker switch
is required with at least a 3 mm gap between its
contacts (in deactivated state).
