Fig. 21: B24 connection scheme; actuator BELIMO
NOTES:
• Caution! Main power supply voltage!
• Parallel connection of several actuators possible.
• Power consumption and switching thresholds must be observed!
• When power supply is connected to wires 1 and 3,
actuator drives to position OPEN.
• When power supply is connected to wires 1 and 2,
actuator drives to position CLOSED.
• Circuit switch between wires 2 and 3 is not part
of the damper delivery.

NOTES:
• Caution! Main power supply voltage!
• Supply via isolation transformer.
• Power consumption and switching thresholds
must be observed!
