Figure 2-4 shows the terminal block arrangement and
terminal designations for the transmitter.
NOTE:
All terminals are suitable for single wires up to 14
AWG (2.5 mm
2
).
Wiring Tip!
To comply with European Community (CE) electromag-
netic compatibility requirements, follow these general wiring guidelines:
1. Locate transmitter as far as possible from motors and other non-
CE certified devices with excessive electromagnetic emissions.
2. Use GLI-specified ferrites and cables. Failure to do so may elimi-
nate compliance.
Locate all ferrites as close as possible to the
transmitter.
◆
DC Power Supply Cable (GLI 1W0980 two-conductor plus
shield): Connect cable shield to earth ground at the supply
end. Loop cable 2-1/2 times through ferrite (Steward
#28B0686-200, Fair-Rite Corp. #2643665702 or equivalent).
◆
Analog mA Output Cable (four-wire hookup only -- GLI
1W0980 two-conductor plus shield): Connect cable shield to
earth ground at the supply end. Loop cable 2-1/2 times
through ferrite (Steward #28B0686-200, Fair-Rite Corp.
#2643665702, or equivalent).
