Failure to observe the installation instructions may result in fire or a danger of electric shock. The device is part of the building installation. Observe the relevant national standards and directives during planning and installation.
The device is intended for operation on the Homematic IP Wired Bus only. The Homematic IP Wired Bus is a SELV power circuit. The mains voltage for the building installation and the Homematic IP Wired Bus must be routed separately. Com-mon cable routing for power supply and the Homematic IP Wired Bus in installation and junction boxes is not permitted. The required isola-tion for a power supply of the build-ing installation to the Homematic IP Wired Bus must be observed at all times.

The device must be installed on a mounting rail (top-hat rail, DIN rail) in accordance with DIN EN 60715. Installation and wiring must be carried out in accordance with VDE 0100 (VDE 0100-410, VDE 0100-510). The pro-visions of the technical connection regulations (TAB) of the energy sup-plier must be observed.
Observe the permissible cable types and conductor cross sections when connecting to the device terminals.

The device is suitable for use only in residential environments.

General system information

This device is part of the Homematic IP Smart Home System and communicates via the Homematic IP. Operation requires connection to a Homematic IP Wired Access Point. Further information on the system requirements and installation planning is to be found in the Homematic IP Wired system manual.

Function and device overview

The Homematic IP Wired Input Module – 32 channels can be easily installed on a DIN rail in a power distribution panel. The 32 inputs can be used to connect several switches and push-buttons. Lamps or other lighting systems can then be switched or dimmed via paired Homematic IP Wired switching or dimming actuators.

You can also configure individual inputs of the module as sensor inputs in order to monitor e.g. NC or NO contacts.
The device offers a special function for the use of mains voltage push-buttons or switches. You can activate “corrosion protection” for each input to prevent corrosion and possible functional limitations of the buttons/switches. This ensures that a higher current flows briefly through the push-button/switch when it is actuated. The current pulse prevents corrosion. The function is deactivated in the default settings and can be activated separately for each channel.

Installation instructions

Read this section completely before starting installation.
Make a note of the device number (SGTIN) and the installation location of the device before installation to make it easier to identify the device later. The device number can also be found on the enclosed QR code sticker.
Please observe the hazard warnings during installation see Hazard information, .

The inputs are not disconnected from the mains voltage and provide the bus voltage. Connected push-buttons, switches or other switching elements must be specified for a rated voltage of at least 26 V.
Please note the insulation stripping length of the conductor being connected, as indicated on the device.
For electrical safety reasons, only the supplied Homematic IP Wired Bus cable or an eQ-3 Homematic IP Wired Bus cable of another length (available as an accessory) may be used for connecting the Homematic IP Wired Bus. d.

You can connect push-buttons/switches or normally closed/normally open contacts to the device.
Rigid cables can be plugged directly into the clamp terminal (push-in technology). Press the white operating button on top of the terminal to connect flexible conductors or to disconnect all types of conductors.
If changes to or work on the house installation are necessary (e.g. extension, bypass of switch or socket inserts) or to/on the low-voltage distribution system for mounting or installing the device, the following safety instructions must be ob-served:

The installation may only be carried out by persons with the relevant electrical engineering knowledge and experience!*

Incorrect installation can endanger

your own life,

and the lives of other users of the electrical system.

Incorrect installation also means that you are running the risk of serious damage to property, e.g. due to fire. You risk personal liability for personal injury and property damage.

Consult an electrician!

Specialist knowledge required for installation:
The following specialist knowledge is particularly important during installation:
The “5 safety rules” to be used:
- Disconnect from mains
- Secure against restart
- Check for absence of voltage
- Earth and short circuit
- Cover or cordon off neighboring live parts
Selection of suitable tools, measuring equipment and, if necessary, personal protective equipment;
Evaluation of measuring results;

Selection of electrical installation material for safeguarding shut-off conditions;
IP protection types;
Installation of electrical installation material;

Type of supply network (TN system, IT system, TT system) and the resulting connection conditions (classic zero balancing, protective earthing, required additional measures, etc.).

Permitted cable cross sections for connecting to the device are: rigid and flexible cable, 0.25 – 1.5 mm²

Selecting the supply voltage

The voltage supply to the device is made only via the Homematic IP Wired Bus. The bus is fed by the Homematic IP Wired Access Point (HmIPW-DRAP) Operating manual HmIPW-DRAP.
The maximum total current consumption is calculated from the actual number of inputs used. Approx. 4 mA flows through each actuated input; if all inputs are used in sensor mode with NC contacts; this results in:
An average current consumption can be expected in normal applications with mixed operation of push-buttons, switches and signalling contacts (16 push-buttons, 8 NC contacts and 8 switches). The push-buttons only influence the current consumption if they are operated and are therefore negligible. Since only closed switches must be taken into account, it is possible to use an average value here (half is the switches are closed). The NC contacts are permanently closed and must there be taken into account entirely. This results in an exemplary total current consumption of:

Assembly and installation

Proceed as follows to install the device on a DIN rail:

Disconnect the power distribution panel and cover any live parts, if required.
Disconnect the corresponding line of the incoming Homematic IP Wired bus.

Remove the cover from the power distribution panel.
Place the device on the DIN rail.
You should be able to read the letters on the device and in the display.

During installation, make sure that the locating springs engage properly and that the device is securely seated on the rail.
Wire the device according to the connection drawing and observe the installation instructions see Installation instructions, page 6.
Connect the bus connection cable to bus port 1 or bus port 2 and connect all other wired devices via the bus.

Use the supplied bus blind plug, if bus connection 1 or bus connection 2 are not needed.
Fit the cover of the power distribution panel again.
Switch the fuse of the power circuit on .

Switch the Homematic IP wired bus on to activate the pairing mode of the device.
