WARNING!
Risk of electric shock to persons!
In addition to this document, all information in the description of the power adapter, which is in the power adapter packaging, must be observed.

Information
If the description included with the power adapter cannot be read and un- derstood due to the available languages, then use the description in the re- quired language from the homepage of the manufacturer.

General instructions

WARNING! Risk of electric shock to persons!

• The Embedded PC must always be installed safely isolated from electric circuits with hazardous voltage.
• The power adapter must not be made user accessible.

ESD information

Electronic component are generally put at risk by electro-static discharges (Electro Static Discharge). An electro-static charge can occur during any ac- tivity involving movement. ESD can occur with any touch.
Most discharges are so low that they are not noticeable. However, they can nevertheless put unprotected electronic components at risk or even destroy them. Therefore, any handling with open electronics is only permissible with the application of effective ESD protection.

When handling open electronics, please follow the following ESD measures:

• Only touch open electronics if this is absolutely necessary.
• Wear a conductive ESD wristband.
• Use conductive mats.
• Establish a conductive connection between device/system, mat, wrist-band, and grounding connection.
• Cotton work clothes are preferred over synthetic fiber materials.
• Keep work area free of highly isolating materials (e.g. Styrofoam, plas-tics, nylon, …).
• Use ESD protection even for defective modules.

Always keep the devices in their original packaging and only remove the packaging immediately before installation.
Avoid, for modules which are mounted in an enclosure, direct contact with any accessible electronic components, such as non-equipped terminals.

Space requirement

Embedded PC

The specifications are minimum distances. If a USB stick is used in opera- tion, more space may need to be taken into account.

Installation in the control cabinet

Information

• When positioning the KeContact M20, you must make sure that it does not block access to existing control cabinet components.
• The SIM card may need to be installed before the mounting is done. Otherwise, installation is no longer possible.

The KeContact M20 can be mounted on a top hat rail. The mounting pack-age includes two brackets (one has a shorter depth) and a mounting clip.

Information
The screw holes in the KeContact M20 for the mounting package are sym- metrical. The mounting package can be mounted on any side of the Ke-Contact M20.

Required materials and tools:

• 3x M3 screws, 5 mm length (included in the scope of delivery)
• Phillips screwdriver PH1 (not included in the scope of delivery) Proceed as follows to mount the KeContact M20 on the top hat rail:

1. Unscrew the M3 screws on the side of the housing.
2. Secure the short bracket (2) on the KeContact M20 with two M3 screws (max. torque of 0.59 Nm, tolerance ±0.05 Nm).
3. Secure the long bracket (1) on the KeContact M20 with two M3 screws (on the opposite side of the short bracket). The long bracket must be above the short bracket.
4. Secure the mounting clip on the brackets with three M3 screws.
5. Check whether the mounting package is mounted as follows:
6. Mount the KeContact M20 on the top hat rail.
7. If necessary, establish protective grounding for the mounting package. The KeContact M20 is installed on the top hat rail.

Wall installation

The KeContact M20 can optionally be installed on a wall. Wall brackets are needed to do this. These are not included in the scope of delivery and can be ordered as accessories.
The four screw holes are located on the underside of the KeContact M20.

To install the KeContact M20 on the wall, proceed as follows:

1. Unscrew the M3 screws on the underside of the housing.
2. Secure the two wall brackets (1) on the KeContact M20 with four M3 screws.
3. The KeContact M20 can be installed at various distances from the wall using the predrilled screw holes.
4. Install the KeContact M20 on the wall.
   The KeContact M20 is installed on the wall.

Air conditioning and ventilation.

CAUTION! High temperatures may irreparably damage the device!

• The operating temperature inside the control cabinet must not exceed the permissible ambient temperature of the KeContact M20. If this can-not be guaranteed through natural heat dissipation, an air conditioning of the control cabinet must be provided.

Connections and wiring

CAUTION!
Fire hazard from transient currents
The shield of the Ethernet interface is not galvanically isolated. If there are connections to a device outside the building installation or to another equipotential bonding system, there may be high transient currents. In this case, use suitable optical transmission of the Ethernet interface.

Power supply

• The KeContact M20 may only be supplied using the power adapter included in the scope of delivery (in the control cabinet) using the DC-In jack.
• The primary supply of the power adapter is the responsibility of the respec-tive electrician (power connection line not included in the scope of delivery).
• The power adapter is to be used in environments with contamination no greater than contamination level 2 (as per EN 61010-1). All safety notes and specifications of the power adapter manufacturer must be observed.

Information
Contamination level 2, description according to standard EN 61010-1: Usually only non-conductive contamination appears; however, temporary conductivity caused by condensation must be expected on occasion.

Mounting the antenna

CAUTION! Danger to life from electromagnetic fields
To adhere to the limit values for people’s exposure to electromagnetic fields, it is necessary to mount the antenna at least 25 cm away from people.

Mounting the antenna directly on the device

To mount the antenna, proceed as follows:

1. Switch off devices connected to the KeContact M20 and disconnect their power cables.
2. Tighten the antenna (2) at the antenna connection (1).
   The antenna has been installed.

Mounting the antenna on the control cabinet

To mount the antenna, proceed as follows:

1. Switch off devices connected to the KeContact M20 and disconnect their power cables.
2. Unscrew the locknut and remove it and the washer from the antenna.
3. Feed the antenna cable into the control cabinet through a predrilled hole (for M10 screw).
4. Pull the adhesive film off the antenna, align the antenna and press it on the outside of the control cabinet.
5. Use the washer and locknut (included in the scope of delivery) to fasten the antenna on the inside of the control cabinet (max. 5 Nm).
6. Tighten the antenna cable at the two antenna connections.
   The antenna has been installed.
