Programming adapter
The IS programming adapter is marked with an IS circle
logo and has the product code:
■
T03-22009-AAAA (AEx and Canada)
■
T03-22009-ADAA (IECEx and EU)
Warning Explosion hazard!
Do not use the IS
programming adapter in a hazardous location.
You must use the IS programming adapter with an IS/NI
radio, as its internal circuitry provides additional protection
for the IS/NI 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.
Equipment repair
Warning Explosion hazard!
IS/NI radios and
accessories are not user-serviceable. IS and NI radios
and accessories must be serviced only by an agency
certified by both the approval authority and by Tait Limited.
Any unauthorized repair or substitution of parts invalidates
the intrinsic safety or non-incendive rating and the third
party IS or NI approval. To have an IS and NI radio
serviced, return it to your regional Tait office.
Rating matching
The rating of the radio, battery and accessories must be
reviewed to ensure a safe IS/NI radio system. IS/NI
ratings must be “matched”, and the lowest approval level
determines the overall IS/NI radio system approval.
Equipment labels clearly identify the item’s ratings.
