Installation
● Comply with operating ambient restrictions (see “Technical data [➙ 6]”
）。
● Do not twist the cable.
● Strong magnets may disturb or damage the actuator.
● A means of isolation from the power supply must be provided. For example, connecting a
circuit breaker or fuse switch upstream of the actuator and controller.
WARNING
No internal line protection for supply lines to external consumers.
Risk of fire and injury due to short-circuits!
● Adapt the line diameters as per local regulations to the rated value of the installed over-
current protection device.
Commissioning
1. Before commissioning, always check the wiring and test the functions.
2. Make sure the mechanical limit switches of the actuator is consistent with the damper's
On/Off position.
3. When commissioning, adjust the damper shaft or linkage to make sure that, the actuator's
auxiliary switch is triggered and positioning signal is sent out when the damper is in the
On/Off position.
4. Factory setting of the position limit is 0...90°. Do not adjust the limit during commissioning to
ensure normal operation.
