DC/DC converter control devices
The figure shows an example of the door control devices of the DC/DC converter. The
selection and exact location of control devices varies in different deliveries.
DC switch/disconnector (F286)
The DC switch/disconnector [Q11.xx] is optional (F286). The DC
switch/disconnector has an operating handle on the cabinet door. A converter unit with a
DC switch/disconnector also has a precharge circuit including a charging switch on the
door.
The DC switch/disconnector allows the isolation of the unit from the DC bus. Before the
unit is reconnected to the DC bus, the capacitors of the converter modules must be
charged through a charging circuit.
WARNING!
You must also switch off the charging switch to disconnect the DC/DC
converter from the DC supply. Do not operate the DC switch/disconnector under
load.
Charging switch
A converter unit with a DC switch/disconnector ([Q11], F286) also has charging
circuit and a charging switch [Q10.x] on the cubicle door. Before closing the DC
switch/disconnector, close the charging switch. After the precharging completes, the
Charging OK indicator [P11.x] (green) on the cabinet door illuminates, and you can close
the DC switch/disconnector [Q11.xx], and open the charging switch.
Note:
You must open the charging switch before you can start the converter unit.
