instructions:
Installation

XA00091R• 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 housing of field display must be connected to the potential
matching line.
• Only the approved wire entries as specified in paragraph 10.3 ofEN/IEC 60079-14, paragraph 16 of EN/IEC 60079-0, paragraph 13of EN/IEC 60079-1 must be used.
• For connection through a conduit entry approved for this purpose theassociated sealing facility shall be mounted directly to the housing.
• Seal the cable entries with certified cable glands and or blanking
elements which have at least type of protection Ex db.
• For operating the display housing at an ambient temperature under-20°C, appropriate cables and cable entries permitted for thisapplication must be used.
• For ambient temperatures higher than +70°C, use suitable heatresisting cables or wires, cable entries and sealing facilities for Ta+5K above surrounding.
• During operation, the cover must be screwed all the way in and thecover's safety catch must be fastened.

LWARNING
Explosive atmosphere‣ Do not open the electrical connection of the power supply circuit in
an explosive atmosphere.

Safetyinstructions:
Specificconditions of use• The flameproof joints are not intended to be repaired.
• 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.
