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

).
Wiring Tip!
To comply with European Community (CE) electromagnetic
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.
3. Loop these cables through the specified ferrite using the required
number of loops:
◆
DC Power Supply Cable (GLI 1W0980 two-conductor plus
shield): Connect cable shield to earth ground at the supply
end. Loop cable 4 times through ferrite (Fair-Rite Corp.
#2643102002 or equivalent).
◆
Sensor Cable: Keep cable shield as short as possible and
connect it to the SHIELD terminal. Loop cable 3-1/2 times
through ferrite (Fair-Rite Corp. #2643804502 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 4 times through
ferrite (Fair-Rite Corp. #2643102002 or equivalent).
