3.5 Electrical connection
The measuring transmitter MyPro CLM 431 /
CLD 431 has separate connection compart-
ments for the power supply and measuring
cell connections.
The terminals for the two-wire line are located
under the screwed cover on the right side of
the instrument.
Proceed as described below to connect the
MyPro CLM 431 / CLD 431:
• Connect the MyPro CLM 431 / CLD 431
transmitter to a 12 ... 30 V power source
• Ground the instrument via the outer
ground terminal.
• Ground the two-wire line screen via the
ground terminal in the connection
compartment.
Note:
•Keep the screen ground line as
short as possible. Connect the
screen directly to the ground
terminal. This also applies to
connection of junction box VS.
•If the instrument is mounted on a
post, ground the post to increase
immunity to interference. Running
the cable in the post will improve
interference suppression.
•Immunity to interference is only
guaranteed when the instrument is
grounded via the shielded two-
wire line.
