9. If required secure the cable to the tower or structure with cable ties or clips. DO NOT bundle this
grounding cable with any other cable used for data, power or RF.
Cautions
When using the anti oxidizing paste read and follow the instructions and warnings for the selected
product. In addition you should note the following general guidelines:
•
The paste will act as a lubricant, therefore always use lock washers.
•
DO NOT apply the paste to RF and data cable connections: the anti-oxidizing paste is conductive
and may degrade the performance or damage the equipment.
•
DO NOT use electrical or other tape for sealing the grounding connections when using anti
oxidizing paste
•
DO NOT use thread-locking compound on the same screw with anti oxidizing paste.
Inspect the grounding connections on a regular basis as well as after a lightning strike. Look for
cables that may have been damaged or connections that may have loosen up or oxidize over time.
Replace any damaged cables or connectors and tighten any loose connections.
3.2.3 Power/Ethernet cable
Connect the outdoor cylindrical connector of the CAT5e cable to port D of the radio. The other end
of this cable (with an RJ45 connector) plugs into the indoor Power Inserter Unit.
You can optionally install the Ethernet/Power Surge Suppressor module (SUP-0202) at the point
where the CAT5e cable enters the building. This protects your indoor equipment against surges
induced by nearby lightning on the outdoor CAT5 cable. The surge suppressor has two RJ45
connectors and a ground wire, which you must connect to an earth ground.
If you use a DC source to power the radio, make sure you do not exceed the CAT5e cable length
specified in the table below. At port D the radio requires 8 VDC. With the DC voltages shown (at
the power inserter), the maximum cable length results in an input voltage at the radio of 8 VDC. The
radio includes a voltage monitor which you can read with the
>show command. This can be useful to
determine the status of your battery for a battery-powered installation.
