ZCU-14 default I/O connection diagram
The diagram shows the control connections of the supply unit, and the default meaning
or use of the signals in the supply unit control program.
The wire size accepted by all screw terminals (for both stranded and solid wire) is
0.5 … 2.5 mm
2
(24…12 AWG). The torque is 0.5 N·m (5 lbf·in).
Note: As the same control program is in use with different diode supply types, the
default connections shown are not applicable to them all. For example, some units
have a DC link charging circuit, some do not. The default parameter settings and I/O
connections are valid for the version without the charging circuit.
