Security 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 ● ● ● The device offers plug & play functionality. The device receives its power from the connected room automation station via the KNX PL-Link interface, or from the jack connector.
CAUTION The devices are not protected against accidental connection to AC 230 V. ● ● ● Use the correct cables for the KNX PL-Link bus. Do not interchange the wires of the KNX PL-Link cable. Observe all local installation regulations. Commissioning Prerequisites Before commissioning the device, make sure an application is downloaded into the connected controller, from where the functions are downloaded in the device. Download the application using SSA-DNT (Pack & Go) or ABT.
Manual commissioning When automatic commissioning fails or when multiple devices are connected, manually commission the device as follows: Addressing 1. Connect SSA-DNT or ABT to the controller and activate the online commissioning function. 2. Load web page "KNX PL-Link identification". Activate the identification function. a The controller now waits for a signal from the device. 3. On the device, simultaneously press buttons 1 and 8 for at least 5 seconds. a The "Engineering" page is displayed. 4.
Press button 4. The device is locked and reboots within 10 seconds. The controller removes the device from its device list. During this time, the device can safely be removed from the network. If the bus plug remains connected, the device acts like a newly inserted device requiring automated or manual configuration. Programming pin and service LED The devices come with a programming pin and a red service LED on the rear. Addressing 1. Briefly press the programming pin (<0.5 s).
Reset to factory setting Press the programming pin (>20 s). The device is locked and reboots within 10 seconds. The room automation station removes it from its device list. During this time, the device can safely be removed from the network. NOTICE! The LED is off during this procedure. If the bus plug remains connected, the device acts like a newly inserted device requiring automated or manual configuration. NOTICE This operation resets all user-defined data and configuration settings to factory default.

Standards, directives and approvals UL compliance UL916 FCC compliance Part 15 of the FCC rules. Operation is subject to the following two conditions: 1) this device may not cause harmful interference, and 2) this device must accept any interference received, including interference that may cause undesired operation.
To locate the KNX PL-Link plug, see Mechanical design [➙ 3] Note: Users can select either pair of pins for connection. NOTICE Wires are not interchangeable! The device is protected against faulty wiring, but communications does not work on interchanged wires. Do not connect the KNX / KNX PL-Link bus to the tool plug, only the tool.
Service tool Connect ABT to load the application in the controller, or for service purposes: ● Directly to the controller ● To the device using the tool cable and the OCI702 service interface (see data sheet A6V10438951) Dimensions 12 Siemens A6V10733768_en--_b 2020-04-29
