Approvals for Specific Configurations – Certified Drawings
Several specific configurations of Remote Meter Assemblies have been approved for use in hazardous
locations by various approval agencies. Each of these specific configurations has been documented by
Honeywell in controlled Engineering Drawings that are certified by Honeywell and approved by the
appropriate body (FM, CSA, and CENELEC). Copies of the certified drawings are included in this
publication at the end of this section.
For descriptive purposes, a stylized, “generic” sample of these drawings in given in Figure 7, below.
As indicated in Figure 7, each drawing or set of drawings shows alternate wiring methods for placing the
meter between the Power Supply/Control Equipment/Approved Associated Apparatus and the Transmitter,
or for placing the meter at the end of the wiring loop. In many cases, wiring methods are similar for several
configurations approved by various notified bodies. However, notes that specify entity parameters and
special conditions are unique for each approval agency and for each configuration covered by that
approving body. It is very important to select the correct drawing(s), and to comply with all notes
regarding special conditions in the drawings.
When installed in ordinary, non-hazardous locations, wiring shall comply with National Electrical Code
(NEC) or with local electrical code requirements.
WARNING
For use of the RMA in hazardous locations, It is the user’s responsibility to select the appropriate
engineering drawings, and to ensure that all conditions specified in those drawings are adhered to in every
respect.
