Abide by the following precautions when using separate power supplies for the
input points.
Connect according to one of the following methods when the same power supply
is used for input points 1 and 2.
1. Use shielded twisted-pair cable for external connections.
2. Connect the positive and negative terminals of any unused input points to
3. Use separate power supplies for input points 1 and 2 whenever possible. In
4. If the same power supply must be used for input points 1 and 2, connect the
1. Connect shield terminal to signal supply common terminal.
2. Connect resistors from the shield to the positive and negative terminals.

the shield terminal.
this case, the shield terminal must be shorted to the negative terminal, as
shown in the diagrams above. Failure to do so may cause errors of several
percent in the output data.
wiring as shown in the diagram below.
The connections shown in the previous diagrams should not be used for a
single power supply, because the internal connections of the shield termi-
nals for input points 1 and 2 inside the Unit cause interference between the
input points and inaccurate data will result.
Connect as shown in previous diagram (1) for voltage input signals in com-
mon mode.
