Connecting External Antenna Cable (optional)
If the RouterBOARD was purchased with external antenna connector option,
screw the connector of the antenna cable cable on the appropriate antenna
attachment of the case. Hand tighten the connector (do not use vice grips for
this job). When tying the coaxial cable, make sure no water can get into it and/
or into the equipment it is attached to. It is very important to seal the connec-
tion properly with a good rubber tape made particularly for this purpose (note
that many general purpose tapes will not prevent moisture to leak into con-
nector, or will fail after some time). Note: do not bend the cable straight: you
should keep a radius of curvature allowing the cable to bend without applying
force.
Safety Precautions
IMPORTANT: LIVES MAY BE AT RISK! Contacting power lines may cause
injury or death. Make sure that in no case may equipment or personnel come
in direct or indirect contact with power lines. All overhead wiring should be
assumed to be power lines. Ensure that the mast may not contact power lines
even if it falls during or after installation. If a person comes in contact with
electricity and is not able to move, you MUST NOT touch that person to avoid
the same fate! Instead, use a known non-conductive stick or rope to pull him/her away from the electric line.
Respect safety procedures when working above the ground. Do not work alone: a friend or co-worker can save your life in case of
an accident.
Grounding
The installation infrastructure (towers and masts), as well as antennas and the device itself (there is a small screw with a wing nut
on the case with a sticker identifying chassis grounding), must be properly grounded, and lightning arrestors must be installed on
all external antenna cables (near the antennas or on the antennas themselves) to prevent equipment damage and human injury.
Note that lightning arrestors will not have any effect if not grounded. Note also that damages caused by static electricity and light-
ning are not covered by warranty.
Use 1 AWG (7mm in diameter) wire with corrosion-resistant connectors for grounding. Be sure to check that the grounding infra-
structure you use is indeed functional (as opposed to decorative-only grounding present on some sites).
