DC 24 V Venetian blind actuator: electrical connection
Connecting the device
Only for DC motors 12...48 V. Observe the admissible load ratings.
Terminals 1/2 supply power to the device electronics and outputs A1 and A2. For op-
eration of the actuator it is necessary to connect an external 24 V DC power supply
to 1/2.
Terminals 3/4 supply power to outputs A3 and A4.
The supply voltages must be designed in such a way that a safe and reliable operat-
ing voltage is provided under all load conditions – especially when the motors are first
switched on.
Do not connect any AC voltage.
￭
Connect power supply to terminals 1/2 or 3/4 (see figure 3).
￭
Connect motors to load terminals A1 ... A4 (see figure 3).
