Hardware description
31
Digital input and relay output terminals
The DSU can be controlled through two control interfaces: local and remote. The
operation switches placed on the cabinet door are connected to the local control
interface. The remote control interface can be used in parallel when control by other
external devices is needed.
DSSB board terminals
1)
After the power switch-on, the DSU first charges the contactor control
capacitors (~ 3 s at first start) and checks the fault status. DSU starts rectifying
only after the contactors are closed by the START input.
2)
These DSSB board terminals are wired to a separate terminal block to which
the user connections are to be made. See the circuit diagrams delivered with the
unit.
