power supply. This so-called inrush current can be several times higher than normal current
consumption but will last only few ten milliseconds. For proper operation it is crucial to assure
that the power supply has output power rated to higher than the maximum power consumption of
the device and that the power supply can handle short inrush currents properly. Device can be
grounded using its housing with its DIN RAIL mount. Grounding point is eventually marked to
the housing with Ground – label.
Grounding the antenna is recommended when antenna is located outside on a mast or long pole
where it is prone to lightning strikes or other high energy disturbances.
Grounding is best to locate as near as possible to the expected disturbance to occur, in practice at
the point where the antenna is fixed to a structure. Wiring the antenna ground and/or cable shield
should be done to a ground rail or other reliable common ground with shortest possible cable
length to avoid high resistance ground loops. If grounding cable is needed to be longer thicker
cable should be used accordingly.
It is not recommended to use the mast only as a grounding conductor as its conductivity can’t be
always guaranteed
Safe Installation check list
Electronic devices are sensitive to external influences which should be taken into consideration
while taking the device into operation. Proper place for assembling is necessary for good
performance and long life span. Even though device is built to withstand external vibrations,
shocks, temperature fluctuations and high/low temperatures still those occurrences should be
avoided as much as possible to maximize the durability and longevity of the product. High
temperature decreases the lifespan of the components whereas vibration and shocks weaken the
mechanical structure and can drastically affect the performance in use.
The following points must be taken into account when installing and configuring a device:
All operating voltages of all the equipment concerned must always be switched OFF before
connecting the serial interface cable.
voltage output of the power supply must be stable and with sufficient current capability
check correspondence of Serial interface settings between device (DTE) and the terminal unit
(DCE)
Check placement of device and its antenna:
o
antenna should be installed in open space as far as possible from any possible sources of
interference and humans;
o
not onto a strongly vibrating surface
o
minimize exposure to direct sunlight or excessive humidity.
Check Interference.
This equipment generates, uses and radiates RF and, if not installed and used in accordance
with the instructions, may cause harmful interference to radio communications. However,
there is no guarantee that interference will not occur in a particular installation; if equipment
causes harmful interference, which can be determined by turning the equipment off and on,
the user is encouraged to try to correct the interference by one or more of the following
measures:
o
Reorient or relocate the receiving antenna
