The radio shall be installed by trained personnel only, as outlined to the installation instructions
provided with each radio.
The equipment shall be installed by a qualified installer/electrician. The installer/electrician is
responsible for obtaining a secured ground connection between the lug terminal on the surge
protector to a verified common ground point using a minimum 18 gauge wire. This must be done
when attaching power lines to the radio during installation. .
A solid ground connection should be verified using a meter prior to applying
power to the radio. Failing to secure a proper ground could result in serious injury
or death as a result of a lightning strike.

Cable specifications
The recommended cable is category 5 or better. A category 5 cable has four
twisted pairs of wire that are color-coded and cannot be swapped. The radio
uses only two pairs. One pair uses pins 1 and 2, and the second pair uses pins 3
and 6.
Use a straight-through cable when connecting the radio to an Ethernet hub or a
10/100 Base-T Ethernet switch. Straight-through cables are used in most cases.
Use a cross-over cable when connecting the Ethernet radio directly to any device
that is NOT a switch or a hub (e.g., a direct connection to a PC, PLC, or printer).
Ethernet cabling is like U.S. telephone cables, except that it has eight
conductors. Some hubs have one input that can accept either a straight-through
or crossover cable, depending on the switch position. In this case, you must
ensure that the switch position and cable type agree.
Refer to Ethernet cable configuration (page 83) for a diagram of how to configure
Ethernet cable.
