Technical Design
  • Rail-mounted device for installation on 35 mm rails as per IEC 60715, connected to the bus via a terminal block and powered by bus voltage.
  • Each output has a potential-free relay with a switch position display.
Technical Data
  • Power supply: KNX bus voltage DC 24 V, current 20 mA.

Overview: This document provides guidelines for planning and constructing electric installations, emphasizing adherence to national guidelines, regulations, and standards.
Installation Notes: Designed for fixed installations in interior spaces, specifically in dry locations, within distribution boards or small casings with DIN rails EN 60715-TH35. Maximum current via load terminals should not exceed 20 A.
Commissioning: Outlines the process of connecting loads to switching contacts, specifying the use of copper wires with diameters from 0.5 to 2.5 mm². Includes a procedure for checking the connection to channels, manually or via bus commands.
Warnings: Manual operation of the slide switch is for emergency or testing purposes during installation. It does not send a telegram to the bus, and the changed switch position is not registered by the device. In case of bus failure or recovery, a manually switched relay will revert to its parameterized switching state.
Testing: Describes a test for KNX 24 V DC type SELV to ensure correct polarity and bus voltage supply. A long press of the programming button (over 20 seconds) resets the device to factory settings.
Dimensions: Provides dimensions for the device, including various measurements in millimeters and inches.
Product Documentation: Additional documents such as operating and installation instructions, application program descriptions, and product databases can be downloaded from the Siemens website.
Support: For technical support, contact details are provided, including phone numbers and an email address. Links to FAQs and support requests are also included.

The device is a rail-mounted device in N dimension for installation in arrangements and is installed on 35 mm rails as per standard IEC 60715. The switching actuator is connected to the bus connection with a bus terminal block. The power supply is supplied via the bus voltage (no additional power voltage is required). Every actuator output has a potential-free relay with switch position display. Via the relay, the switch position can be changed with a tool. Every actuator output has one terminal each for the supply voltage (rated operating voltage AC 230 V) and the switched load. The maintenance-free...

Behavior with bus voltage failure/recovery In case of bus voltage failure, the current switch status and other values for each output are permanently stored. On bus voltage recovery, these values are restored. For each channel, the configured actions are also executed and, if applicable, new status values are reported. Behavior on unloading the application program After "unloading" the application program with the ETS, the unloaded device has no functions. Timer functions When configuring the device with ETS, one timer and night mode can be programmed. It is possible to set delayed switching...

Switch cycle and operating hours count To monitor use, with the right configuration it is possible to count and display the switch cycles and operating hours of the device. For switching actuators of type N 535, the counting of operating hours can be configured so that operating hours are only counted when there is an active current flow. Load current monitoring (only type N 535) For switching actuators of type N 535, the load check can optionally be measured and the status can be sent via the bus. The load check can also be monitored with regard to exceedance or falling short of load check limit...
