The non-metallic cover of the Wireless Ethernet Modem is considered to constitute an
electrostatic discharge hazard. Clean only with a damp cloth
The Wireless Ethernet Modem enclosure contains aluminum and is considered to constitute a
potential risk of ignition by impact or friction and must be taken into account during installation.
If the Wireless Ethernet Modem is installed as Category 3 equipment, then it shall be installed
in an Enclosure which maintains an ingress protection rating of IP54 and meets the enclosure
requirements of EN 50014 or EN60079-0.
If installed in a hazardous environment coaxial cable shall be installed in a metallic conduit as
per NEC requirements
