DANGER
HAZARDOUS AREA INSTALLATION
INTRINSICALLY SAFE INSTALLATION
Transmitter/Sensor is not Intrinsically safe.
Installations in hazardous area locations must be
carefully evaluated by qualified on site safety per-
sonnel. To secure and maintain an intrinsically safe
installation, an appropriate safety barrier must be
used and the installation must be performed in
accordance with the governing approval agency
(FM, CSA or BASEEFA/ CENELEC) installation
drawing requirements (see Section 2.0-Installation).
EXPLOSION-PROOF INSTALLATION
Sensors are not explosion-proof and must be
installed in a non-hazardous location. If the sensor
must be installed in a hazardous location an intrin-
sically safe system must be implemented. To main-
tain the explosion-proof rating of the transmitter,
the following conditions must be met:
• Discontinue power supply before removing
enclosure covers.
• Transmitter covers must be properly installed
during power on operation.
• Explosion proof "Y" fittings must be properly
installed with sealing compound prior to applying
power to the transmitter.
• Serial tag cover over the external Zero and Span
adjustments must be in place.
• See Installation Section for details.
Proper installation, operation and servicing of this
instrument in a Hazardous Area Installation is
entirely the responsibility of the user.
