DRAFT 2
Warning Ensure that the ratings printed on a label on
the equipment will permit your IS radio and
accessories to be used in your hazardous location.
The operating temperature range for IS radios and
accessories in hazardous locations is –4°F to +104°F
(–20°C to +40°C). In safe locations it is –4°F to
+140°F (–20°C to + 60°C).
IS radios, batteries, antennas and accessories must
not be engraved or modified in any way. Do not use
the radio if it is cracked or damaged. Do not use the
antenna if the sheathing is split or the end cap is
missing. IS 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
rating and the third party IS approval. To have an IS
radio serviced, return it to an authorized Tait branch or
subsidiary.
Warning Use only a Tait-supplied, IS-approved
battery, antenna, audio accessory or carry accessory
with an IS radio. Fitting a battery or accessory that is
not IS-approved exposes the customer to a risk of
explosion which could cause serious injury or death.
For an up-to-date list of approved accessories, refer to
“TP9300/TP9400 IS Portable Radios Approved IS
Accessories” on the Tait website, or contact your
nearest Tait office.
Warning Do not charge the battery, or change the
antenna, in a hazardous location. An explosion could
cause serious injury or death.
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 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.
