Control electronics for D8T modules
Cabling of the electronics outside the supply and inverter module must be done by the
customer. The current consumption of the main components in the auxiliary circuit is
shown in Auxiliary circuit current consumption on page 335.
Control unit
You must equip each supply and inverter unit with one control unit (and memory unit).
Supply modules and inverter modules require their own control units. The delivery includes
the control units.
The BCU control unit kit contains:
• BCU control unit
• ZMU memory unit with the control program.
For the dimension drawings, see section BCU control unit on page 388.
The following option module is to be installed on the BCU control unit and must be ordered
separately:
• RDCO-04C DDCS communication option module (ordering code: 68882915).
Fiber optic cables
The fiber optic cables are needed for supply and inverter modules. You need one pair of
cables (kit) per each module and between the two RDCO-04 option modules. Select a kit
with suitable length.
The following kits, each consisting of a pair of plastic fiber optic cables, are available from
