Safetyinstructions:
Installation• Comply with the installation and safety instructions in the OperatingInstructions.
• 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.

Safetyinstructions:
Specific
conditions of use• 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 type of protection for the process transmitter changes as follows
when the devices are connected to certified intrinsically safe circuitsof Category Ex ib: Ex ib IIC. When connecting an intrinsically safe Exib circuit, do not operate the process transmitter at Zone 0 / EPL Ga.
• The permitted category of the intrinsically safe circuit for the processtransmitter depends on the type of protection of the respective
associated apparatus used.
