Identification Each device has a unique serial number to ensure efficient commissioning. It is provided on the adhesive barcode label. The serial number can be read directly into the engineering tool using a barcode reader. Wiring Wiring must be sufficiently insulated to the available rated voltage. Sizing and fusing of the wiring depends on the connected load. Triac outputs AC 24 V Individual Triac outputs may have a max. load of 6 VA (heating up the device). The following possibilities are permitted: • Multiple motorized actuators with a total of max. 6 VA. • 1 thermal actuator with 6 VA...

The room automation stations can be snapped onto standard rails or screwed onto a flat surface. Strain relief Strain relief protects flexible electrical wiring against mechanical stress. The wiring must be fixed using cable binders to the tabs on the housing base. Terminal cover Break off the cable inlets to insert the cables to the room automation station.
