CAUTION
• To meet the EC Directive for Electromagnetic Compatibility (EMC), use a suitable instrumentation cable
to connect the meter. The instrumentation cable should have individual screens, foil or braid over each
twisted pair, and an overall screen to cover all cores. Where permissible, connect the overall screen to
earth at both ends (360° bonded at both ends). Connect the inner individual screens at only the
controller end.
• Use metal cable glands where the cables enter the meter amplifier box. Fit unused cable ports with
metal blanking plugs.
4.5 Wiring to signal converters and/or flow
computers
For meters with a Time Period Signal (TPS) output, you can wire the meter to an signal
converter or flow computer directly. The following information provides wiring diagrams
for making those connections in safe and hazardous environments.
When wiring the meter to an active HART host or signal converter/flow computer, you are
not required to provide external power to the output connections. These active devices
provide the 24 VDC necessary for these connections.
