Description
Intended use (areas of application)
Refer to the chapter 2 Product description for detailed specifications for the area of application. The operational safety of the device is only assured when used as intended in accordance with the specifications in the operatingmanual.
Intervention beyond the actions described in the operating manual may only be carried out by personnel authorised by the manufacturer for safety and warranty reasons. Conversions or modifications made on one's own authority are expressly prohibited.
Application-specific dangers can emanate from this device when used improperly or not as intended.
The device is not intended for use in explosion-prone areas and safety-related system parts in accordance with SIL.
Only device versions TV125M-Ex, TV125MP-Ex, ST125M-Ex and ST125MP-Ex are permitted for use as operating equipment for connection of intrinsically safe sensors, installed in Zones 0 or 1 and/or 20 or 21.
All safety-relevant characteristic data must be observed in this connection. (see 6.1 Safety-related key values)
The approval for all intrinsically safe operating equipment is voided if it has been previously connected to nonintrinsically safe power circuit, because compliance with the safety-relevant characteristic data cannot be 100% guaranteed there.
Therefore, a safety test must be conducted by the manufacturer before later use as an intrinsically safe operating device.
The device TV125MP-00, ST125MP-00 and all other versions of the series TV****-Ex and ST****-Ex can be installed in the explosion-prone
Zone 2 under the following conditions:
Installation in a clean environment in a conductive, earthed housing (switch cabinet) with a minimum protection rating of IP54.
Disconnection of connecting terminals only takes place in the de-energised state Standards:: EN 60079-0 und EN 60079-7
