2600T SERIES | PRESSURE TRANSMITTERS | OI/266/FF-EN REV. E
Simple FF network and system architecture
Wiring procedure
Follow these steps to wire the transmitter:
• Remove the temporary plastic cap from one of the two electrical connection ports located at both sides in the upper part of the
transmitter housing.
•
threads to comply with plant wiring (conduit) standards.
• Remove the housing cover of the “field terminals” side. See the indication on the label on top of the housing.
In an Explosion-Proof / Flame-Proof installation, do not remove the transmitter covers when power is applied to the unit.
• Run the cable through the cable gland and the open port.
• Connect the positive lead to the “+” terminal, and the negative lead to the “–” terminal.
• Plug and seal the electrical ports. Make sure that when the installation has been completed, the electrical ports are properly
sealed against entry of rain and/or corrosive vapors and gases.
WARNING - GENERAL RISK
Cable, cable gland and unused port plug must be in accordance with the intended type of protection (e.g. intrinsically safe,
explosion proof, etc.) and degree of protection (e.g. IP6x according to IEC EN 60529 or NEMA 4x). See also the “EX SAFETY”
ASPECTS AND “IP” PROTECTION. In particular, for explosion proof installation, remove the red temporary plastic cap and plug
the unused opening with a plug certified for explosion containment..
• If applicable, install wiring with a drip loop. Arrange the drip loop so the bottom is lower than the conduit connections and the
transmitter housing.
• Put back the housing cover, turn it to seat O-ring into the housing and then continue to hand tighten until the cover contacts the
housing metal-to-metal. In Ex-d (Explosion Proof) installation, lock the cover rotation by turning the set nut (use the 2mm Allen
key supplied with the instrument).
