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.
