INSTALLATION
3.1
General
This section describes the installation and infrastructure requirements for the FMA300.
Departure from the instructions contained herein may void any warranty provided by SRK.
3.2
Environmental
The transmitter is intended for indoor use. The transmitter should be protected from rainfall
and direct sunlight, extremes of temperature and humidity and from conditions of high dust
levels. Ambient temperature should be in the range +10°C and +30°C. The transmitter shall
not be operated at altitudes in excess of 3500m above sea level. The transmitter must be
installed on a flat, stable surface. The transmitter must be installed in the upright position.
The transmitter must be installed in a location free from vermin and the ingress of other
animals. The transmitter shall not be installed in locations prone to flooding. All ventilation
orifices must be clear to allow adequate air flow.
3.3
Electrical supply
The electrical supply to the transmitter must be of the voltage, form and frequency described
in the specifications. All electrical wiring must be carried out in accordance with local laws,
standards and regulations. If power supply voltages regularly fall outside specifications then
a voltage regulator must be installed between the supply inlet and the transmitter.
3.4
Earthing
Adequate earthing of the transmitter is vital to ensure long term reliability and user safety.
The electrical supply must be earthed, via the earthing pin of the IEC connector. In countries
where power outlet earthing is merely optional, an earthed outlet must be used. See safety
notice at the front of this manual. A separate, independent, earth is required for the
transmitter/antenna system and must be connected to the earthing point indicated on the rear
of the transmitter. The cable used to connect the earth should be as thick as possible, with 8
AWG being the smallest size acceptable. Where possible, broad earthing band should be
used.
In addition to the earth connection to the transmitter, the outer conductor of the coax feed to
the antenna should be connected to the earth, as indicated below.
The earth itself must be of high quality buried copper, at least 1.5m deep and preferably in
ground that is habitually humid (eg, the base of a gutter down pipe).
