6.2 Electrical mounting
■ The instrument must be grounded via the process connection!
■ The power supply for the pressure transmitter 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 opera-
tion above 2,000 m should the pressure transmitter 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).
