2.
Field wiring must be suitable for a minimum of 110°C.
3.
Ethernet Switches are intended for mounting in an ATEX-Certified IP54 enclosure in a pollution degree 2
environments as defined by IEC 60664-1.
4.
Temperature testing of the Ethernet Switches was conducted on the switch itself in an 85°C air circulating
oven and resulted in a Temperature Code of T4. However, end-product temperature testing shall be
considered.
5.
The end user shall provide bonding means as necessary. All bonding equipment (components) shall be
