МТ-700 fleet tracking system 31
The
antenna should be mounted horizontally, or have a slight angle to the
horizon, with the magnet facing down, as far as possible from the radioemmiting devices
(emitting antennas, radio stations, ignition block, etc).
Above the antenna there should be no metal units or other entanglement parts.
Possible options for mounting the GPS antenna are shown in
Figure 27
.
If the vehicle is equipped with the windshield heating the GPS antenna
should NOT be mounted under the windshield!
Also, some automotive paint and varnishes may contain traces of
metal, that may generate a EM-shield, which can cause problems for the
GPS.
Mounting the GPS antenna under these elements is FORBIDDEN!
Antennas should be plugged to corresponding jacks on the terminal.
While connecting the jack it should be properly tightened, so there is no slippage.
Connect and disconnect antennas only while the tracker is in power-off mode.
After connection the jack can be isolated using an electrical tape or a heat-shrink tube.

Power connection
Power to the terminal is delivered on the wires 1 and 7 in the power connector ( Figure 28 ).
For powering the device wires no less than 0,5 mm
2
should be used .
The vehicle’s wiring should provide more then 10A current loads(cross-section of more
than 0,75 mm
2
), the voltage between the wires should be equal to the onboard system’s voltage
and constant over the ignition’s on and off process, starter hit and other equipment .
The required positive wire should be wired through the fuse (package included). The
safety fuse must be placed as close as possible to the entry point.
