Remarks:
1.
No revision to this drawing without prior approval of FM.
2.
Installation must be in accordance with the Canadian Electrical Code (CEC)
CSA22.1, 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.

WARNING－POTENTIONAL ELECTROSTATIC CHARGING HAZARD – SEE
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.
DANGER POTENTIEL DE CHARGES ÉLECTROSTATIQUES – VOIR LES
INSTRUCTIONS
Les sondes de pH contenant des pièces en plastique accessibles et / ou des pièces
conductrices externes doivent être installées et utilisées de manière à éviter tout risque
d'inflammation dû à des charges électrostatiques dangereuses, en particulier dans le cas
où le fluide de procédé n'est pas conducteur.
