6.2 Electrical mounting
■
The instrument must be grounded via the process connection!
■
The power supply for the pressure sensor must be made via an energy-limited electrical circuit in accordance
with section 9.3 of UL/EN/IEC 61010-1, or an LPS to UL/EN/IEC 60950-1, or class 2 in accordance with UL1310/
UL1585 (NEC or CEC). The power supply must be suitable for operation above 2,000 m should the pressure
sensor be used at this altitude.
■
Select a cable diameter that matches the cable gland of the plug. Make sure that the cable gland and sealings are
assembled correctly and that they are undamaged.
■
Protect the cable end from humidity, which otherwise might intrude into the instrument.
Sealing of the process connection
Parallel threads
Tapered threads
Correct sealing of the process connections with parallel
threads at the sealing face
must be made using
suitable flat gaskets, sealing rings or WIKA profile
sealings.
For sealing process connections with tapered threads,
the sealing must be made in the threads using additional
sealing material - e.g. PTFE tape (EN 837-2).
