12.2. INTRINSICALLY SAFE MOUNTING
The mounting of PR-01-S-FM must be in accordance with the National Electrical code (ANSI/NFPA70).
For installation guidance of the PR-01-S-FM, see also ANSI/NFPA 12.6 “Installation of Intrinsically safe
instrument systems in Class I Hazardous Locations”. Choose the mounting location of the sensor, barrier
unit and indicating transmitter so that they are protected from sudden impact and friction. If any of the
system parts is affected by a sudden impact, power it off immediately and have it checked by trained
K-Patents service personnel before it's used again.
The electrical connections for PR-01-S-AX are described in Figure 12.21, for PR-01-S-FM in Figure 12.22
and for PR-01-CS in Figure 12.23 for following two alternatives:
– Connections by instrumentation cable
– Connections by armored instrumentation cable
