6 Safety Recommendations
The I300 board contains ESD (electrostatic discharge) sensitive devices.
Electrostatic charges readily accumulate on the human body and equipment where
discharge can occur without detection. Permanent damage may occur on devices
subjected to high energy discharges. Proper ESD precautions are recommended to
avoid performance degradation or loss of functionality. Store any unused I300
boards in anti-static packaging.
The I300 uses an integrated Telit UC864-G cellular modem. The use of the I300
may be dangerous and has to be avoided in the following areas:
• Where it can interfere with other electronic devices in environments such as
hospitals, airports, aircrafts, etc.
• Where there is risk of explosion such as gasoline stations, oil refineries, etc.
Antenna characteristics must match those specified in this document and care must
be taken during in
stallation to avoid any interference with other electronic devices.
There must be a minimum separation between an antenna and the human body of
20 cm.
The I300 incorporates reverse voltage protection and surge protection against DC
voltages not exceeding 50v DC.
Additional protection is recommended when operating from non regulated or
vehicle power supplies.
It is recommended that an inline fuse be fitted when operating from a vehicle
supply.
The power GND input corresponds to the I300 chassis ground and external power
isolation must be used where there is a risk of accidental connection to mains level
voltages.
It is the responsibility of the final unit manufacturer to ensure that the use of the
I300 is allowed in the country where the unit is sold and that all necessary
certification for the unit is in place.
Do not disassemble the I300 or attempt repair. Any mark of tampering will
invalidate any warranty.
