Supply Wiring Requirements - ABB 2600T Series Instructions For Installation And Commissioning

PHASE 3 - TRANSMITTER WIRING
8. 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. In case an Output meter is
present, be sure that the by-pass connection is open, then
plug the meter into the appropriate socket.
9. 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 EEx-d (Explosion Proof) installation, lock the cover
rotation by turning the set nut (use the 2mm Allen key
supplied with the instrument).
In case of FF or Profibus connections see the relevant diagram.
For further information find the relevant instruction manuals
searching for the keyword "IM/*26*" on www.abb.com or from
local ABB representatives.

SUPPLY WIRING REQUIREMENTS

For signal/power connection use twisted, stranded pairs of
wiring no 18 to 22 AWG / 0.8 to 0.35mm
(1500 meters). Longer loops require larger wire.
If a shielded wire is used the shield should be grounded only at
one end, not both ends. In case of wiring at transmitter end, use
the terminal located inside the housing marked with:
cover locking screw
