EN 5.1 Unpacking
When unpacking, do not use any sharp objects (e.g. cutter knives), as this may damage the cable.
Submersible pressure sensors with cable lengths >100 m are wound on cable drums and wrapped with foil.
Unwind the foil manually. The end of the foil is marked with blue tape.
5.2 Suitability for the process conditions
All components of the instrument that are in contact with the process must be suitable for the process conditions that
may exist. Included in this are particularly the process pressure, process temperature and also the chemical proper-
ties of the media. Prior to commissioning, the suitability of the instrument must be ensured (→ for specifications, see
chapter 9 "Specifications" and the product label).
5.3 Requirements for mounting point
The mounting point must meet the following conditions:
The diaphragm is protected from contact with abrasive media and against any impacts.
■
The cable contains a capillary for the pressure compensation. Therefore, the cable must be connected in a dry
■
space or a suitable terminal enclosure.
Sufficient space for a safe electrical installation.
■
Permissible ambient and medium temperatures remain within the performance limits.
