Section 4 – Installation
1. Overview.
This section provides general information for planning the installation of the E-Compact High Power Line
Transmitters, such as recommendations regarding Shelter, Tower, Antennas, Cables, Grounding, Power
Line, Prevention against transients, etc.
2. Inspection.
The package and the equipment must be inspected upon delivery in order to detect eventual visible
damages. If there are signs of violation or physical damage (which points to transportation problems), the
corresponding details should be described in the delivery documentation provided by the transport
company. Such notice would be used to establish the responsibilities for the product integrity.
Comark carries out operating tests at the factory on every transmitter in order to ensure proper operation
after delivery to the user. Nevertheless, if the equipment does not operate after the start-up and there is
no evidence of transportation damage, it might be necessary to send the equipment back to the factory
for repair or replacement. In such a case, please get in contact with Hitachi Kokusai Electric Comark LLC's
customer support.
3. Installation Recommendations.
3.1. Preventive Protection
Voltage transients with a duration of micro and nano-seconds are a constant challenge for solid state
circuits. The downtime and the equipment maintenance make the preventive protection the best warranty
against these surges. This protection can be in many forms, from isolation transformers and no-breaks to
the more efficient but more expensive AC Voltage Protectors. Since lightning is the most common cause
of transients, AC Voltage Protectors are the best choice.
An efficient AC Voltage Protection must be able to dissipate the energy to a low voltage, sufficient to
guarantee the protection of the electronic components. The protection must always be placed transversely
to the AC line, even during blackout periods. In addition, it must be immediately and automatically turned-
on and ready in case of repeated transients.
3.2. Tower
For the installation of the transmission and reception system, the tower must be made with hot-dip
galvanized steel. A lightning protection system should be installed in the tower as well as nocturnal
beacons bulbs with red glass.
