Installations in Europe
To comply with CENELEC standards for hazardous area installations in
Europe, adhere to the following CENELEC conditions for safe use:
• Use 3/4"-14 NPT cable glands or conduit fittings, rated flameproof for
EEx d IIC areas and certified by an authorized test station. Flameproof
glands supplied by Micro Motion meet these requirements.
• Conduit openings that are not used should be sealed with blanking
plugs of type PLG 2.
• For installation in a nonhazardous area, cable glands or conduit fittings
that do not carry a flameproof rating are acceptable.
A CENELEC-compliant RFT9739 includes a lockout clamp on the
transmitter housing. See
Figure 4-2
. The clamp adds secondary
protection against accessing the power-supply terminals, and is required
to meet CENELEC standards.
