Making The Electrical Connection; Connection Diagrams - Festo SPAW B2R Mode D'emploi

6. Commissioning, operation
6.1 Making the mechanical connection
The sealing faces at the instrument always have to be clean.
■
Only ever screw in, or unscrew, the instrument via the spanner flats. Never use the case as a working surface.
■
The correct torque depends on the dimensions of the pressure connection and the gasket used (form/material).
■
EN
When screwing in, do not cross the threads.
■
Seal
Correct sealing of the process connections at the sealing face must be made using suitable seals.

6.2 Making the electrical connection

The instrument must be earthed 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.
Long signal cables reduce the immunity to interference. Make sure that the length of the signal cable is always
■
shorter than 30 m. In this way you can avoid non−operate currents caused by electromagnetic interference.
For cable outlets, make sure that no moisture enters at the cable end.
