Installation Guidelines Regarding Power Line Quality

IMPORTANT
•
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 CSAT 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 CSAT provides a grounding terminal. This is provided to allow the user to
ground the CSAT 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
CSAT except for the ground wire. Cap all RF connections with terminations. This will prevent
damage to the input/output circuitry of the CSAT.
•
Lightning: Lightning strikes on or around the antenna will generate extremely high voltages on
all cables connected to the CSAT. Depending on the severity of the strike, the CSAT's internal
surge protection combined with the recommended external suppression may protect the CSAT's
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)

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.
