General precautions
•
Check all ground connections. During the hardware installation they must be completed
before power and communication cabling.
•
Create drips loops where cable connects to product, to prevent water collecting on
device connectors.
•
Cables should be kept as short as possible, to minimize chance of interference and voltage
drop.
•
All cables between antenna and radar system units should be routed as directly as
possible, consistent with consideration for other equipment, in order to reduce
electromagnetic interference effects.
•
Cables should not be installed close to high-power or high frequency conducting cables,
such as radar or radio-transmitter lines, large DC motor cables.
•
Where cables intersect, try to stay at right angles (90°) to minimize inductance of noise.
•
Only use suitable waterproof connectors when joining cables.
•
If a cable being pulled through a concealed area requires excessive force to finish pulling
through the remaining cable, consider rerouting cable via an alternative route – otherwise
cable conductors may get broken, the cable sheath & insulation may be damaged, or the
same damage may be done to adjacent cables, which may cause a fire.

Up-mast transceiver cables
It is advised to run the cables starting at the up-mast transceiver location, working towards
the power supply and control unit console:
•
Gravity feeding of cables in radar tower conduit is naturally easier, especially where no
draw wire is available.
•
The Ethernet plug is smaller at console end: 20mm plug diameter vs 36 mm plug.
•
The power cable is un-terminated at the POWER SUPPLY end, whereas up-mast
transceiver end has 36 mm plug.
Ú
Note:
Minimum bend radius of the Ethernet cable is 100 mm. Do not subject the cable
to tighter bends, as distortion of the cable can degrade the cables performance, and at
worst may break conductors due to fatigue.
