Notes Safety CAUTION National safety regulations Failure to comply with national safety regulations may result in personal injury and property damage. ● Observe national provisions and comply with the appropriate safety regulations. Engineering 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.
PAGE 6
Mounting The room automation stations can be snapped onto standard rails or screwed onto a flat surface. CAUTION Risk of overheating for failure to comply with ambient temperature Burning and damage to the device ● Ensure sufficient ventilation to comply with the permissible ambient temperature within the panel or installation box. The temperature must be 10° C (18° F) lower outside the installation box. Mounting position Ambient temperature -5...45 °C (23...113°F) Ambient temperature -5...50 °C (23...

Operation The outputs have no electricity when power fails. USB communications that does not work points to improper grounding of AC 24 V operating voltage (connection ⏊ must be grounded). Disposal The device is considered an electronic device for disposal in accordance with the European Guidelines and may not be disposed of as domestic garbage. ● Dispose of the device through channels provided for this purpose. ● Comply with all local and currently applicable laws and regulations.
