INSTALLATION

7.If one of the two electrical conduit entrances in the housing is not used, it should be plugged. Refer to the Transmitter's nameplate and Section 8.1 to determine whether entrance holes accept ½-14 NPT or M20 x 1.5 fittings.

Seal ½ NPT fittings with TFE/PTFE tape; seal M20 fittings with a soft setting sealing compound rated for at least 105°C (221°F).

4.6 HAZARDOUS AREA INSTALLATION

Drawings showing Transmitter installation data for hazardous areas are located in Appendix B. Entity parameters, barrier selection, and important wiring information are specified on these drawings. The Appendix also contains a list of tested barriers.

Before installing a transmitter in a hazardous area, check the nameplate and Sections 8.1 and 8.3 of this Manual for required approvals or certifications.

NOTE

The MXC is approved for use in non-hazardous areas only.

EXPLOSION-PROOF INSTALLATION

If the installation is required to be explosion-proof per the National Electrical Code, refer to a current copy of the Code and the following:

ŸUser supplied explosion-proof conduit seals (glands) are required on transmitter housing conduit outlets and any installed junction boxes. See Figure 4-11.

ŸExplosion-proof glands must provide a good seal. Apply a sealing compound around the sealing surface if necessary.

ŸSensor and power wiring conduit entries at the Transmitter must have a minimum of five threads fully engaged.

ŸThe enclosure cap must be installed and have a minimum of eight threads fully engaged with no damaged threads permitted.

ŸGo to Section 4.5 for wiring connections to the transmitter's terminals. Refer to Appendix B for hazardous area installation information.

This completes the physical installation.
