Cable Specifications
For this wiring, use a 2-core or a 4-core shielded cable.
Wiring Procedure
(1) M4 screws are used for the terminals of the converter. Each wire in the cable should be
terminated corresponding to crimp-on terminals. Ensure that the cable shield is connected
to the FG terminal of the converter.
(2) Be sure to connect “+” and “-” polarities correctly.
5.2.7 Contact Output Wiring
Contact outputs 1 to 3 can be freely assigned to “low limit alarm”, “high limit alarm”, etc. user
selectable, but the assignment of contact output 4 is fixed (“error output”). And the action (contact
closed on error output) also cannot be changed.
When using these contact outputs, install the wiring as follows:
