G/D or m1 (with nAmur intrinsic
safety barrier)
• Use a shielded cable with an operating temperature
suited to the process.
• Use an intrinsic safety barrier with NAMUR input and a
power supply, both complying with the safety instructions
and with the ATEX instructions notice.
• Earth the shielding of the cable on side of the
measuring exploitation.
• Before wiring the device, Plug out the female
connector.
