6.2.3 Connections between separately mounted sensor unit and transmitter
Terminals for wiring connections with the sensor unit are found on the side of transmitter housing.
Remove the cover and make wiring connections.
①
Using a flat tool, loosen the separately mounted
sensor cover by slowly turning it counterclockwise
and further counterclockwise by hand until it comes
off. (Be careful to avoid damaging the finish.)
②
Separating the separately mounted sensor cover
provides access to the terminal block (screwless
terminal block) for the sensor.
6.3 Power Supply Lines and Ground Terminal
() Power source primary lines are connected to
terminals L (
＋
) and N (
－
).
(Overvoltage Category II, Pollution Degree .)
() Connection to earth ground terminal:
Connect only to GND on the power terminal
block or external ground terminal.
External ground
terminal
CAUTION: Supply voltage must be within
the range shown in the
product nameplate attached
to the housing.
6.4 Analog Output Wiring
When analog output ( to 0mA) is to be connected to a receiving instrument, Analog Output has
terminals A (
＋
) and terminal A (
－
) while Analog Output has terminal A (
＋
) and terminal A (
－
).
Maximum load resistance is 00
Ω
. Analog output setup procedure appears in .7. Analog output
functions.
※
Analog output will be invalid if FOUNDATION fieldbus, PROFIBUS PA is selected as communication
interface.
