Safetyinstructions:
Installation• Comply with the installation and safety instructions in the Operating
Instructions.
• Install the device according to the manufacturer's instructions andany other valid standards and regulations (e.g. EN/IEC 60079-14).
• The indicator housing must be connected to the potential matchingline.
• The type of protection changes as follows when the devices areconnected to certified intrinsically safe circuits of Category ib: Ex ibIIC.
• When connecting an intrinsically safe ib circuit, do not operate theprocess transmitter at Zone 0.
• The indicator must be installed so, that even in the event of rareincidents, an ignition source due to impact or friction between theenclosure and iron/steel is excluded.
• The circuits of indicator are isolated from its enclosure inconformance with EN/IEC 60079-11 chapter 6.3.13.

Safetyinstructions:
Specific
conditions of use

When the enclosure is provided with an non-conductive coating,electrostatic charges on the equipment enclosure shall be avoided. For
more details see safety instructions.
