on connector 2 (or 4). Terminal points +U
V
on slot 2 (or 4) are connected internally to
terminal point +U

on slot 1 (or 3) (see
Figure 2). Therefore, the selected voltage at
+U
V
is available on slot 1 (or 3) (see also
"Connection examples" on page 10).

7 Installation instructions
High current flowing through potential jumpers U
M
and U
S
leads to a temperature rise in the potential jumpers and
inside the terminal. Observe the following instructions to
keep the current flowing through the potential jumpers of
the analog terminals as low as possible:
8 Connection notes
Connecting the strain gauges
Shield connection
Unused channels
For unused channels, follow the instructions for
parameterization (see notes on bit 15 on page 15).
Create a separate main circuit for the
analog terminals
If this is not possible in your application and if
you are using analog terminals in a main circuit
together with other terminals, place the analog
terminals after all the other terminals at the end
of the main circuit.
Connect the strain gauges using shielded
twisted pair cables.
Only connect the shielding at one point,
preferably to the terminal. If the shield is
securely connected to the sensor, insulate the
shield on the terminal side.
