Before the instrument is opened to install the wiring, FCI recommends that ESD precautions be
observed. See Page 11 for ESD instructions.
Wiring
Preparation
This section wires the transmitter inputs, outputs and interconnection cabling for the instrument.
Route the output wiring through the opposite port from the power wiring. The maximum gauge of
wire to use is 16 AWG. See Table 1 on Page 16 and Table 2 on Page 17 for the maximum
distance that wires can be run.
Only qualified personnel are to wire or test this instrument. The operator assumes
all responsibilities for safe practices while wiring or troubleshooting. CAUTION:
ALERT: The instrument contains electrostatic discharge (ESD) sensitive devices. Use standard
ESD precautions when handling the flow transmitter.
Wiring the
Instrument
Wiring the Flow Element
Connect a shielded, 8 wire cable between the transmitter and the local enclosure terminal strip as
shown below. Be sure the shield (ground wire) is connected to JP3 GND along with the wire from
terminal block terminal 2. Do not connect the shield to the local enclosure (leave it floating).
Alternate 8 wire, ST98 Type Flow Element wiring shown in VeriCal and 2 point Averaging System
sections, see Operations Section 4.0.
