ABB DV889-7000-20 Thyristor controlled silicon battery

Description

The system is protected with adequate internal fusing. In addition to fusing distributed to
different apparatus, there are common miniature circuit breakers in the power switch and
distribution units in the cabinets (see the terminal diagram form for the actual power supply
system).
The superior distribution board fusing protects the equipment with respect to:
• Internal fusing in the Advant Controller
• Rated current of connected equipment
• In-rush current at power switch-on
• Need to protect the power supply cables to the equipment installed.
For a guide to dimensioning the fusing, see below.
When necessary, you can make a more accurate current consumption calculation to obtain exact
data for fusing. This calculation should focus on the actual number and type of circuit boards in
the different subracks.

No extra software is needed, the basic system QC07-BAS41 is sufficient.
No extra hardware is needed besides the desired I/O unit if:
• Spare slot in an I/O subrack is available (S100 I/O)
• MasterFieldbus communication is available (S400 I/O)
• Advant Fieldbus 100 and an S800 I/O station is available (S800 I/O).
Supported I/O boards (S100 I/O), I/O units (S400 I/O) and I/O modules (S800 I/O) are listed in
Section 1.7, Product Overview. Besides the board/unit type designation, you can also find
information about suitable connection units and internal cables in that section. Further
guidelines are given below
