14 For your safety
Antenna
Use only genuine Tait-supplied antennas. Antennas are
not specifically rated and may be used in any area,
subject to the rating restrictions of the overall radio
system.
Programming adapter
The IS programming adapter is marked with an IS circle
logo and has the product code:
■ T03-22009-ADAA (IECEx and EU)
You must use the IS programming adapter with an IS
radio, as its internal circuitry provides additional protection
for the IS circuitry in the radio. All programming activities
are permitted. Calibration activities are only permitted if
the activity can be done with the programming adapter
alone. Other connections (e.g. antenna port) are not
permitted. The IS programming adapter is not approved
for use in any hazardous location.
Rating matching
The rating of the radio, battery and accessories must be
reviewed to ensure a safe IS radio system. IS ratings must
be “matched”, and the lowest approval level determines
the overall IS radio system approval.
■
Gas Group IIC rated batteries and accessories may
be used with IIA radios, but the combination may only
be used in a IIA Gas atmosphere.
■
Gas Group IIC and Dust Group IIIC rated accessories
may be used with Gas Group IIA or IIC radios, but the
combination may only be used in a Gas atmosphere.
Any item approved to IIA will limit the radio system to a IIA
area. Equipment labels clearly identify the item’s rating.
