Corrosion is another problem that arises if your cabling system is not properly
weatherproofed. Corrosion can lead to high impedance at contact points, which can
drastically reduce the effectiveness of your lightning protection. To help stop corrosion,
you should use an anti-oxidizing paste on all contacts. When using anti-oxidization
paste, keep the following guidelines in mind:
• read the instructions and warnings for the selected product
• lock washers should be used since the anti-oxidization paste acts as a
lubricant
• use a small amount. A thin film applied to exposed surfaces and on contact
points is adequate
• do not apply the anti-oxidization paste to the data cable connections on the
outdoor unit. The anti-oxidization paste is conductive and may degrade
performance and damage equipment.
• using electrical or rubber tape is not recommended for sealing the
grounding connections when anti-oxidization paste is used
• do not use thread-locking compound on the same bolt or screw as anti-
oxidization paste is used.
5.6 CAT-5 Ethernet Cable Shielding
Using shielded CAT-5 Ethernet cable is very important when installing your LibraPlus
ODU, as it will help in reducing data errors caused by nearby interference.
It is also very important that the shield be connected at only one end of the cable, the
end that connects to the indoor unit. This is required to eliminate ground loops caused
by current flowing between the indoor and outdoor units, due to a possible difference
in ground levels. Such currents can damage equipment at either end or introduce noise
that will interfere with the user data traffic on the cable.
