Step 3. Wiring Preparation
Before the instrument is opened to install the wiring, FCI recommends that the following ESD precautions be observed:
Use a wrist band or heel strap with a 1 megohm resistor connected to ground. If the instrument is in a shop setting there should
be static conductive mats on the work table and floor with a 1 megohm resistor connected to ground. Connect the instrument to
ground. Apply antistatic agents such as Static Free made by Chemtronics (or equivalent) to hand tools to be used on the
instrument. Keep high static producing items away from the instrument such as non-ESD approved plastic, tape and packing
foam.
The above precautions are minimum requirements to be used. The complete use of ESD precautions can be found in the U.S.
Department of Defense Handbook 263.
Open the instrument enclosure to expose the terminal strips. The orientation of the connectors are shown below:
Step 4. Wiring the Instrument
Alert:
The instrument contains electrostatic discharge (ESD)
sensitive devices. Use standard ESD precautions when
handling the flow transmitter.
Caution:
Only qualified personnel are to wire or test this instrument.
The operator assumes all responsibilities for safe practices
while wiring or troubleshooting.
Wiring the Instrument into the Customer Application:
This section describes wiring to the transmitter inputs, outputs and interconnection cabling for the remote enclosure. For best
results route the output wiring through the opposite port from the power wiring. See the table on the next page to determine
the size of wiring to be used versus the length of the wire.
