in industrial environments. For data communication, the devices provide various typical industrial interfaces for
connection to surrounding devices.
This PHYTEC standard gateway is supplied exclusively as an OEM device by PHYTEC Messtechnik GmbH and
requires an adaptation of the operating software for the intended application by the distributor of the device.
2.2 General Safety Instructions
For commissioning, development work, and assembly, the operating instructions for the device must be used.
Knowledge in the following areas is required:
Electronic circuitry
Working in electrostatically protected areas
Accident prevention regulations
On-site valid rules and regulations for occupational safety
These devices may only be commissioned and installed by adequately qualified personnel with basic electrical
knowledge! The device must be handled with care in every phase of its life cycle, in order to prevent destruction by
electrostatic discharge or mechanical stress, for example.
To ensure functional safety, the device must be powered by a SELV/PELV power supply. The gateway must be
mounted on a top-hat rail in a fire save control cabinet for permanent use.
Improper modifications and repairs may impair the integrated protective functions and the electromagnetic
behavior of the device. This can cause malfunction of the device, interference with connected and surrounding
devices, or personal injury. Therefore, work on this device may only be carried out by the manufacturer.
Warning
The device must not be used in a manner not specified in this manual to avoid damage to the protection
provided by the equipment.
L’appareil ne doit pas être utilisé d'une façon non spécifiée dans ce manuel afin éviter d’endommager la
protection fournie par l'équipement.

Warning
To ensure functional safety, the device must be powered by a SELV/PELV power supply. The gateway must
be mounted on a top-hat rail in a fire save control cabinet for permanent use.
Pour garantir la sécurité fonctionnelle, l’appareil doit être alimenté par une alimentation SELV/PELV. Pour
une utilisation permanente, la passerelle doit être montée sur un rail profilé chapeau dans une armoire de
commande coupe-feu.

4.3 Mechanical Connection
The phyGATE Tauri-L gateway housing is designed to be mounted on a top-hat rail in the control cabinet. For
mounting on the top-hat rail, there is a mounting device on the housing which allows a tool-free and safe mounting
on a 35 mm top-hat rail.
Warning
For permanently connected equipment: supply wiring requirements, requirements for any external switch
or circuit-breaker, and external over-current protection devices, we recommend that the switch or circuit-
breaker be near the equipment.

Warning
All signals at connector X27 are galvanically decoupled from the GND reference potential of the board and
the supply voltage of the phyGATE Tauri-L.

Warning
The installation environment, such as the control cabinet in which the device is installed, must meet, as a
minimum, the IP44 specifications and must be fireproof.
L'environnement de l’installation du dispositif, comme l'armoire de commande dans laquelle l’appareil
est installé, doit répondre, au minimum, aux spécifications IP44 et être ignifuge.

Warning
For intended use, the device must be installed on a 35 mm top-hat rail according to DIN EN 60715.
Pour l'utilisation à laquelle il est destiné, l’appareil doit être monté sur un rail profilé chapeau de 35 mm
conformément à la norme DIN EN 60715.

Warning
To prevent malfunction or destruction of the device due to overheating, it is essential to ensure that the
ventilation slots are not covered by surrounding components, cables, and other objects. The air must be
able to circulate freely around the housing to dissipate heat.
Pour éviter tout dysfonctionnement ou destruction de l’appareil en cas de surchauffe, il est indispensable
de s’assurer que les fentes d'aération ne sont pas couvertes par des composants environnants, des câbles
et autres objets. L'air doit pouvoir circuler librement autour du boîtier pour dissiper la chaleur.
