3. Mount the MFC and tighten screws according to IGS torque specifications (see
“Mounting the MFC” on page 3-4).
Making the Electrical Connection
Connect the system to the MFC using an appropriate mating connector and cable. For
electrical connector pin and signal information, see Chapter 4, “I/O Connections and
Communication.”
Note: If possible, securely fasten the connector with jack-post screws to the MFC to
prevent the connector from vibrating loose. Signals at this I/O port can be
sensitive to electrical noise. Take standard preventative measures against
electromagnetic interference (EMI), including using shielded cable.
POWER SUPPLY REQUIREMENTS
For specific power supply requirements, see the specifications for your MFC model in
“Model Specifications” on page 6-1.
Note: The power supply used with the MFC must be sufficient to handle the larger
current demand during operation. Additionally, the ripple voltage of the power
supply should be less than 20 mV.
If needed, Aera recommends using the following Aera power supplies for use with
Aera MFCs:
• PS94UA (For use with up to 4 MFCs)
• PS76DA (For use with up to 6 MFCs)
• PS74DA (For use with up to 4 MFCs)
GROUND CONNECTIONS
The MFC employs both signal and power commons. Proper grounding of these
common leads is essential for the MFC to operate accurately and safely. Improper
grounding practices may result in inaccurate actual and indicated flow. Follow all
appropriate industry and local practices and standards in making these connections.
Note: For electrical connector pin and signal information, see Chapter 4, “I/O
Connections and Communication.”
