Installation ManualMMI-20029969PlanningFebruary 20202Planning2.1Installation checklist If possible, install the transmitter in a location that will prevent direct exposure tosunlight. The environmental limits for the transmitter may be further restricted byhazardous area approvals. If you plan to mount the transmitter in a hazardous area:WARNING— Verify that the transmitter has the appropriate hazardous area approval. Eachtransmitter has a hazardous area approval tag attached to the transmitterhousing.— Ensure that any cable used between the transmitter and the sensor meets thehazardous area requirements.— For ATEX/IECEx installations, strictly adhere to the safety instructionsdocumented in the ATEX/IECEx approvals documentation available on theproduct documentation DVD shipped with the product or at www.emerson.com. Verify that you have the appropriate cable and required cable installation parts for yourinstallation. For wiring between the transmitter and sensor, verify the maximum cablelength does not exceed 1,000 ft (305 m). Ensure that you use the following cables for the different connections:— A certified FOUNDATION fieldbus cable for FOUNDATION fieldbus terminals— A shielded, twisted-pair instrument cable with drain for all output connections You can mount the transmitter in any orientation as long as the conduit openings ortransmitter display do not point upward.Installing the transmitter with the conduit openings or transmitter display facingupward risks condensation moisture entering the transmitter housing, which coulddamage the transmitter.Following are examples of possible orientations for the transmitter.Preferred orientation Installation ManualAlternate orientationsMount the meter in a location and orientation that satisfies the following conditions:— Allows sufficient clearance to open the transmitter housing cover. Install with 8 in(203 mm) to 10 in (254 mm) clearance at the wiring access points.7
PlanningFebruary 2020Installation ManualMMI-20029969— Provides clear access for installing cabling to the transmitter.— Provides clear access to all wiring terminals for troubleshooting.2.2Additional considerations for retrofittingexisting installations The transmitter installation may require 3 in (76 mm) to 6 in (152 mm) of additionalwiring for the input/output and power connections. This length would be in addition tothe currently installed wiring. Confirm you have the additional wiring necessary for thenew installation. Before removing the existing transmitter, be sure to record the configuration data forthe currently installed transmitter. At initial startup of the newly installed transmitter,you will be prompted to configure the meter via a guided setup.Record the following information (if applicable):VariableSettingTagMass flow unitsVolume flow unitsDensity unitsTemperature unitsCalibration parameters (for 9-wire installations only)Flow calibration factorFCF (Flow Cal or Flow Calibration Factor):Density calibration factors— D1:— D2:— K1:— K2:— TC:— FD:Function block settingsChannel assignmentL TypeXD scale (engineering unitsassignment)2.3Power requirementsSelf-switching AC/DC input, automatically recognizes supply voltage: 85 to 240 VAC, 50/60 Hz, 6 watts typical, 11 watts maximum8Micro Motion 5700 transmitters for FOUNDATION Fieldbus
