— Do not install a component in a location where its temperature, humidity, or
vibration limits will be exceeded.
— Maximum distance between components depends on the wire size, the wire type,
and the power supply. Ensure that sufficient power is supplied to the transmitter
terminals.
□ If you plan to mount the transmitter in a hazardous area:
— Verify that the transmitter has the appropriate hazardous area approval. Each
transmitter has a hazardous area approval tag attached to the transmitter housing.
— Ensure that any cable used between the transmitter and the sensor meets the
hazardous area requirements.
— For ATEX/IECEx installations, you must strictly adhere to the safety instructions
documented in the ATEX/IECEx approvals documentation available on the product
documentation DVD shipped with the product or at www.emerson.com/
flowmeasurement.
□ Verify that you have the appropriate cable and required cable installation parts for your
installation. For wiring between the transmitter and sensor, verify the maximum cable
length does not exceed 60 ft (20 m).
□ The transmitter can be mounted in any orientation as long as the conduit openings do
not point upward.
CAUTION
Installing the transmitter with the conduit openings or transmitter display facing
upward risks condensation moisture entering the transmitter housing, which could
damage the transmitter.
□ Minimize the amount of moisture or condensation inside the transmitter housing.
Moisture inside the transmitter housing can damage the transmitter and cause
measurement error or flowmeter failure. To do this:
— Ensure the integrity of all gaskets and O-rings
— Install drip legs on conduit or cable
— Seal unused conduit openings
— Ensure that all covers are fully tightened
□ Mount the meter in a location and orientation that satisfies the following conditions:
— Allows sufficient clearance to open the transmitter housing cover. Install with 8–10
inches (200–250 mm) clearance at the wiring access points.
— Provides clear access for installing cabling to the transmitter.
— Provides clear access to all wiring terminals for troubleshooting.
