1.4.2e Special Conditions for Safe Operation
The “X” at the end of the HygroPro ATEX certificate number,
Bas06ATEX0019X, indicates that special conditions are required for
safe operation in Europe. These conditions are:
1. The equipment must be protected against impact or friction with
ferrous metals.
2. The bare ends of the connecting cable must be terminated in such
a way that the terminations are afforded a degree of protection of
not less than IP20 ingress protection.
3. The HygroPro is incapable of withstanding the 500 VAC test
between all inputs and frame for one minute. Therefore, the
HygroPro must be earthed by connecting the outer grounding
screw on the HygroPro with the equipotential bonding system.
Follow the local standards and electrical codes regarding the
equipotential bonding system.
!WARNING!
Never connect or disconnect the HygroPro in the
hazardous area when supply power or the
communication circuit is energized. Isolate the supply
lines in the non-hazardous area first.
Following the same special conditions listed above is recommended
for regions outside of Europe as well.
