Remarks:
1
No revision to this drawing without prior approval of FM.
2
Installation must be in accordance with the National Electrical Code (ANSI/NFPA 70),
ANSI/ISA-RP12.06.01, and relevant local codes.
3
The sensor shall be installed to a certified intrinsically safe Smart Adapter, model
SA11-P2 with the following maximum values: Uo= 6.6 V, Io = 100 mA, Po = 165 mW.
4
The installers shall take necessary measures to prevent the possibility of sparking
resulting from differing earth potentials between the sensors and interconnecting
equipment. The sensor itself does not provide 500 V rms isolation from earth, the
interconnecting equipment Model SA11-P2 Smart Adapter however provide this
required isolation.

INSTRUCTIONS
pH sensors containing accessible plastic parts and/or external conductive parts, must
be installed and used in such a way, that dangers of ignition due to hazardous
electrostatic charges cannot occur, especially in the case that the process medium is
non-conductive.
