2150EX Module Connected to
2191EX Battery Module and AV2150EX Sensor
Installation should be completed with adherence to local require-
ments for ATEX Group II, Category 1G or 2G equipment as
appropriate, and should be done by trained and qualified per-
sonnel.
Designed for safety The purpose of intrinsic safety is to limit the energy available to
a given circuit or device to a level where electrical discharge
(sparking) cannot ignite the hazardous (flammable or explosive)
atmosphere. With no spark ignition possible, safe operation of
the equipment in areas with hazardous atmospheres is possible.
The durable 2150EX, 2191EX, 2196EX, and 2194EX enclosures
are made with ABS plastic embedded with conductive carbon
fiber, giving the units low surface resistance to minimize electro-
static energy.
The lithium thionyl chloride batteries and the lead acid batteries
used in the 2191EX Battery Module operate at a low voltage and
are contained in sealed battery packs.
The 2150EX system has been designed so that it does not cause
physical injury or other harm due to contact. It does not produce
excessive surface temperature or dangerous radiation. When
used properly, it does not present any non-electrical dangers.
