Safety Instructions ****

Read and observe these safety instructions carefully before installing or commissioning the unit!

To avoid danger to life and limb, the units may only be installed, connected, and commissioned by appropriately trained personnel. This applies to locally supplied units with 230V mains voltage as well as to remotely supplied units with a supply voltage of up to 65VAC. If a unit is damaged, it must be disconnected from the power supply immediately.
To avoid dangerous overvoltages (can e.g. lead to fire hazards and danger to life), care must be taken to ensure proper connection and correct earthing of the connected devices or the entire system installation. In particular, the standards EN 60728-11 and EN 62368-1 must be taken into account and observed with regard to safety. With regard to electromagnetic compatibility (avoidance of excessive emitted interference or too low interference immunity), the standard EN 50083-2 must be observed. It is also important that only high- quality connection cables are used for the signal lines, which have at least a shielding class A (according to EN 50083-2).
The installation site must allow safe routing of all connected cables. Power supply cables and feed cables must not be damaged or crushed by other objects. It is also essential to ensure that no cables come into the direct vicinity of heat sources (e.g. radiators, other electrical appliances, fireplaces, etc.).
Plan the installation site so that you can easily reach the mains plug and pull it out of the socket in case of danger. Select the installation site in such a way that unauthorized persons, especially children, and pets, cannot gain access to the units in order to avoid possible damage to life and limb.
The installation site must be adequately protected against moisture and splash water. It should also not be located in the immediate vicinity of water- bearing pipes or installations so that water cannot get into the units if they are damaged, which could lead to short circuits and fires. This applies in particular to units with open-air vents and to all units that are not protected by an appropriate protection class.
To prevent hazards from falling metal parts and possible short circuits (which could lead to fires), it is mandatory to mount units with ventilation slots according to the preferred direction shown. This always applies as long as the installation is carried out at a height of fewer than 2 meters.
Ventilation slots and heat sinks are important functional elements on the units. For units with heat sinks or ventilation slots, it is therefore essential to ensure that they are not covered or obstructed under any circumstances. Also, ensure that there is ample air circulation around the unit. This will prevent possible damage to the unit and the risk of fire due to overheating.
To avoid both damage to the unit and possible consequential damage, units intended for wall mounting must only be mounted on a flat surface.
For units with a local supply of 230 VAC mains voltage: Before opening the unit, pull out the mains plug or remove the power supply, otherwise, there is a danger to life. This also applies when cleaning the unit or working on the connections. Repairs to the unit may only be carried out by a specialist in compliance with the applicable standards.
If there is a replaceable fuse, pull out the main plug before changing the fuse. Defective fuses may only be replaced by standard-compliant fuses of the same nominal value. If the device is equipped with a protective contact plug or a device socket with a PE connection, the device must be commissioned using a suitable protective contact socket.
For remotely powered units with a maximum supply voltage of 65 VAC: The unit may only be accessed by trained and skilled personnel and may only be opened by them in order to switch the supply voltage on or off via the respective plug-in fuses. The qualified personnel must follow the warnings regarding dangerous voltages. Mounting and fixing the unit: When mounting the device, make sure that the mounting location has sufficient stability with regard to the weight of the device. Screws and dowels required for mounting should be sufficiently dimensioned to hold twice the weight of the unit. Masonry or concrete is recommended as the mounting surface, screws should have a diameter of 4-5mm.
Connection of the protective conductor according to EN 60728-11 clause 6: Protective equipotential bonding system must be carried out via the earthing connection point on the housing (marked with ). A protective conductor with a cross-section of min. 2.5mm² copper (mechanically protected) or 4.0mm² copper (mechanically unprotected) must be used. The cable shield of a subscriber cable must either be connected to the device earth or galvanically separated. The cable shield of a connected antenna that does not have to be earthed must be connected to the unit earth. All earth connections must be made in such a way that the connection can only be disconnected with the aid of tools. The usual connection of a cable shield to the metal body of the socket is sufficient for this purpose.
**Caution, hot surfaces:** The housing surface can become very hot, especially at higher ambient temperatures (from approx. 45°C), so it should not be touched directly during operation.
