Installation Guidelines Regarding Power Line Quality
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 SSPA rovides a grounding terminal. This is provided to allow you 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
transceiver’s internal surge protection combined with the recommended external
suppression may protect the transceiver’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.

Statement of RoHS Compliance
The RoHS (Restriction of Hazardous Substances) directive 2002/95/EC restricts the use of six
hazardous materials found in electrical and electronic products.
Restricted materials are hazardous to the environment and pollute landfills, and are dangerous
in terms of occupational exposure during manufacturing and recycling.
The Two Technologies, Inc. TechTerm Handheld Terminal, used as a serial M&C accessory for
CEFD’s LPOD and SPOD families of products, has been certified to be free of the following
substances mandated under RoHS: lead (Pb), mercury (Hg), cadmium (Cd), hexavalent
chromium (Cr6+), polybrominated biphenyls (PBB), and polybrominated disphenyl ethers
(PBDE).
