.5.2 Intrinsically Safe
An Intrinsically Safe (IS) installation potentially has flam-
mable media present. An approved IS barrier must be
installed in the non-hazardous (safe) area to limit the avail-
able energy out to the hazardous area.
See Agency Drawing – Intrinsically Safe Installation,
Section 3.5.2.
To install Intrinsically Safe wiring:
1. Ensure that the IS barrier is properly installed in the safe
area (refer to local plant or facility procedures). Complete
the wiring from the power supply to the barrier and from
the barrier to the ECLIPSE transmitter.
2. Remove the cover from the wiring compartment of the
transmitter. Install the conduit plug in the unused opening
and use PTFE tape/sealant to ensure a liquid-tight
connection.
3. Install a conduit fitting and pull the supply wires.
4. Connect shield to an earth ground at power supply.
5. Connect an earth ground wire to the nearest green ground
screw (not shown in illustration).
6. Connect the positive supply wire to the (+) terminal and
the negative supply wire to the (-) terminal. (The recom-
mended torque on terminal block screws is 7–10 in-lbs.)
7. Replace and tighten the cover to the wiring compartment
of the transmitter before applying power.
2.5.3 Explosion Proof
Explosion Proof (also referred to as XP or flameproof) is
another method of designing equipment for installation
into hazardous areas. A hazardous location is an area in
which flammable gases or vapors are (or may be) present
in the air in quantities sufficient to produce explosive or
ignitable mixtures.
The wiring for the transmitter must be contained in
Explosion Proof conduit extending into the safe area.
• Due to the specialized design of the ECLIPSE transmitter,
no Explosion Proof conduit fitting (EY seal) is required
within 18" of the transmitter.
• An Explosion Proof conduit fitting (EY seal) is required
between the hazardous and safe areas. See Agency
Specifications, Section 3.5.
