and Ex tc)
■
The connector, which is provided by the user in the final application, must comply with all applicable requirements
of IEC 60079-0 und IEC 60079-15. A minimum ingress protection of IP54 in accordance with IEC 60529 must be
ensured.

1. With the help of the product label, check that the pressure transmitter is suitable for the intended application.
WARNING!
Before installation, commissioning and operation, ensure that the appropriate instrument has been
selected in terms of measuring range, design and specific measuring conditions.
Non-observance can result in serious injury and/or damage to the equipment.
2. The sealing faces and threads on the pressure transmitter and at the mounting point must be clean and without
damage. Clean the sealing faces if contaminated.
WARNING!
Danger of injury and damage to property due to escaping media
Escaping media can lead to serious injury. In the event of failure, components can be ejected or
media exhausted under high pressure.
■
Employ a protective device to prevent parts from being ejected. The protective device must not be
removable without the use of tools.
■
Ensure that the pressure in the system as a whole does not exceed the lowest maximum pressure
of any of its components. If varying or different pressures are to be expected in the system,
components must be used that can withstand the maximum expected pressure spikes.
■
Ensure that the mounting point has been made absolutely free from burrs and is clean.
■
- With pressures ≥ 1,000 bar, use a suitable pressure ring.
