7.2 - Special Conditions
No testing has been carried out in any of the following environments:
•
High altitudes.
•
Pressurised cabins or containers.
•
Explosive atmospheres.
7.3 - Approvals
•
IP67 protection, where 6 means total protection against dust and 7 means protection against immersion
between 15cm and 1m of water for 30 minutes.
C2i only recommends and sells approved sensors. It is the responsibility of the customer to ensure
that all sensors used with the
Entranet
have the appropriate approvals.
7.4 – Safety Features
7.4.1 - Cage Clamp Terminals
Cage clamp type terminals ensure the wires are secure and held reliably, thus the connections have an
increased durability and stability.
Power terminals conductor size is equal to 0.75mm
2
and low voltage terminals conductor size is equal to
0.5mm
2
. Recommend using 0.5mm
2
pin ferrule crimps for easier termination.
7.4.2 - ABS Casing Material
The casing material used for the
Entranet
is acrylonitrile butadiene styrene (ABS) a compound which has
been formulated to meet the static dissipative requirements of the ATEX Directive, thus meeting specific
safety requirements. The Casing has high impact strength and ductility, good chemical resistance and
abrasion resistance. The material is nontoxic, thus handling of the node has no inherent safety risks. The
casing material has high strain tolerance and good resistance to ultraviolet light.
