ATEX Installation Requirements (Standard Voltage Models)
1. The conductor size of the phase conductor must be in the range of 0.05-2.08 mm2.
2. Field wiring must be suitable for a minimum of 110°C.
3. Ethernet Switches are intended for mounting in an IP54 enclosure in a pollution degree 2
environment.
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 evaluated according to EN 60079-15:2005 and covered by a component certificate for the
actual use. When installing bonding components that will pass through an enclosure wall, they
must have a minimum of IP54 rating equal to the enclosure. All electrical clearances must be
maintained per the manufacturer‘s instructions of the bonding component or per EN 60079-
15:2005.
6. Ethernet Switch requires protection against transients. The end-product shall provide a suitable
form of protection that removes the risk of or limits transients to no more than 42V.
