Installation must be performed in accordance with EN 61241-14:2004.
• Transmitters can only be connected using cable glands certified in accordance with Directive
94/9/EC (ATEX) (not included in scope of delivery). The cable gland must conform to IP 67
degree of protection. The smoldering temperature of the dust must be at least 75 K above
the max. surface temperature of the transmitter. The max. surface temperature is 95 °C and
is obtained by adding together the max. ambient temperature (85 °C) and max. self-heating
(10 K).
CAUTION - Risk
When using separating sensors with an anti-stick coating, be aware of the risk of electrostatic
discharge (with consideration given to the medium and transport speed).
