216An POLE MOUNT GROUNDING PROCEEDURES
Mounting the 216An series radio modem outdoors requires proper grounding procedures to prevent damage to both
the radio hardware and the connected Ethernet and Serial peripherals. The case on the 216An series wireless modem
is electrically conductive, but the AA195 Pole Mount kit provides isolation from the connected structure. To bring the
216An case to a ground potential with Earth ground and eliminate any static buildup on the case itself, the shield on the
Ethernet cable is used to provide the ground connection.
Outdoor Ethernet Cable
A critical component of this grounding protection system is the ESTeem AA09.1 outdoor, shielded CAT-5E Ethernet
cable. This cable provides three, necessary elements; Ethernet data, DC Power over Ethernet (PoE) applications, and
a ground from the 216An case to the AA166 surge protector. The Ethernet cable is outdoor rated and protected from
UV breakdown.
Installation
The following diagram outlines all the critical components and connections in the 216An series system. The Earth
ground connection to the surge protector must be installed to comply with local Electrical code requirements.
