Installation guidelines regarding power line quality
As a company with many years of experience selling and servicing equipment installed around
the world, Comtech EF Data has become familiar with the varying quality of the AC power grid
around the world. The following offers some installation guidelines that should help ensure a
reliable installation.
•
Surge suppression: High voltage surges can cause failure of the power supply. These
surges are typically caused by circuit switching on the main AC power grid, erratic
generator operation, and also by lightning strikes. While the transceiver does have built
in surge suppression, if the unit will be installed in a location with questionable power
grid quality, Comtech EF Data recommends installation of additional power
conditioning/surge suppression at the power junction box.
•
Grounding: The transceiver provides a grounding terminal. This is provided to allow
the user to ground the transceiver to the antenna's grounding network. All components
installed at the antenna should be grounded to a common grounding point at the
antenna.
•
Electrical welding: If welding needs to take place at the antenna, disconnect all cables
from the transceiver except for the ground wire. Cap all RF connections with
terminations. This will prevent damage to the input/output circuitry of the transceiver.
•
Lightning: Lightning strikes on or around the antenna will generate extremely high
voltages on all cables connected to the transceiver. Depending on the severity of the
strike, the transceivers internal surge protection combined with the recommended
external suppression may protect the transceivers power supply. However, if the
installation will be in an area with a high probability of lightning strikes, Comtech EF Data
recommends the installation of surge suppression on the RF and IF cables. One source
of these suppressors is PolyPhaser (www.polyphaser.com)
