➂ IEC Installation Instructions:
The cable entry and closing devices shall be Ex d certified suitable for the conditions of use
and correctly installed.
For ambient temperatures above +55 °C or for process temperatures above +150 °C, suitable
heat resistant cables shall be used.
Heat extensions (between process connection and housing) shall never be insulated.
When the equipment is installed in process temperatures higher than +85 °C the temperature
classification must be reduced according to the following table as per IEC60079-0.
< 85 °C T6
< 100 °C T5
< 135 °C T4
< 200 °C T3
< 300 °C T2
< 450 °C T1
These units are in conformity with IECEx KEM 05.0020X
