October 2022
60079-1 & 60079-14 or CSA C22.2 No 30 & UL 1203 for Europe/International and North
America respectively.
Only qualified personnel can select and install these elements in accordance with
EN/IEC 60079-14 for ATEX/IECEx or to NEC/CEC for North America.
• To maintain the Ingress protection thread sealant, a sealing washer, or O-ring must be applied.
— For Zone 1 applications thread sealant must also comply with the requirements of
EN/IEC 60079-14 and thus must be non-setting, non-metallic, non-combustible, and maintain earthing between the equipment and conduit.
— For Class I, Groups A, B, C, and D applications thread sealant must also comply with the requirements of UL 1203/CSA C22.2 No. 30.
• Keep cable away from devices such as transformers, motors, and power lines, which produce large magnetic fields. Improper installation of cable, cable gland, or conduit could cause inaccurate measurements or flow meter failure.
• Improperly sealed housings can expose electronics to moisture, which can cause measurement error or flowmeter failure. Install drip legs in conduit and cable, if necessary. Inspect and grease all gaskets and O-rings. Fully close and tighten all housing covers and conduit openings.
Procedure
1. Run the cable through the conduit. Do not install 9-wire cable and power cable in the same conduit.
2. Remove the junction box cover and core processor end-cap.
3. At both the sensor and transmitter, do the following: a) Connect a male conduit connector and waterproof seal to the conduit opening for 9-wire.
b) Pass the cable through the conduit opening for the 9-wire cable.
c) Insert the stripped end of each wire into the corresponding terminal at the sensor and transmitter ends, matching by color. No bare wires should remain exposed.

Wire the remote core processor to the sensor using shielded or armored cable (9-wire)
Use this procedure to wire the remote core processor to the sensor using shielded or armored cable in a 9-wire remote sensor installation.
Prerequisites
For ATEX installations, shielded or armored cable must be installed with cable glands, at both the sensor and remote core processor ends. Cable glands that meet ATEX requirements can be purchased from Micro Motion. Cable glands from other vendors can be used.
NOTICE
• Keep cable away from devices such as transformers, motors, and power lines, which produce large magnetic fields. Improper installation of cable, cable gland, or conduit could cause inaccurate measurements or flow meter failure.
• Install cable glands in the 9-wire conduit opening in the transmitter housing and the sensor junction box. Ensure that the cable drain wires and shields do not make contact with the junction box or the transmitter housing. Improper installation of cable or cable glands could cause inaccurate measurements or flow meter failure.
• Improperly sealed housings can expose electronics to moisture, which can cause measurement error or flowmeter failure. Install drip legs in conduit and cable, if necessary. Inspect and grease all gaskets and O-rings. Fully close and tighten all housing covers and conduit openings.

The transmitter’s safety parameters require the selected barrier’s opencircuit voltage to be limited to less than 30 VDC (V max
= 30 VDC). This voltage is the combination of the maximum safety barrier voltage
(typically 28 VDC) plus an additional 2 VDC for HART communications when communicating in the hazardous area.
The transmitter’s safety parameters require the selected barrier’s shortcircuit currents to sum to less than 300 mA (I milliamp outputs and 100 mA (I output.

I/O wiring for 2700 with configurable input/outputs
Channel configuration
The six wiring terminals are divided into three pairs, and called Channels A, B, and C.
• Channel A = terminals 1 and 2
• Channel B = terminals 3 and 4
• Channel C = terminals 5 and 6
Variable assignments are governed by channel configuration.

Notes
• For Channel A, the Bell 202 signal is superimposed on the mA Output.
• You must provide power to the outputs when a channel is set to external power.
• When both Channel B and Channel C are configured for Frequency Output (dual pulse),
Frequency Output 2 is generated from the same signal that is sent to the first
Frequency Output. Frequency Output 2 is electrically isolated but not independent.
• You cannot configure the combination of Channel B as Discrete Output and Channel C as Frequency Output.
