Installation of the field indicator• 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).
• Seal the cable entries tight with certified cable which have at least
type of protection Ex tb suitable for Group IIIC (degree of protection
IP6X).

XA00092R• The housing of field transmitter must be connected to the potential
matching line.
• The provided cable entries to option code glands are suitable ATEX/IECEx Ex certified cable glands with a temperature range of -20 °C to+95 °C.
• For ambient temperatures higher than +70°C, use suitable heatresisting cables or wires, cable entries and sealing facilities for Ta+5K above surrounding.

LWARNING
Explosive atmosphere‣ In an explosive atmosphere, do not open the device (ensure that theIP67 housing protection is maintained during operation).
