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.

The in-rush current at power switch-on must be considered at the fuse dimensioning.
Consequently, you must include redundant power supply units (connected to the same line) in
the calculation of number of units. Normally, redundant power supply units are connected to
separate lines.

To reflect the in-rush current and the current rating for the applied power switch and distribution
unit (SV54x), the distribution board fusing should be in the range 10 - 20 A.

For practical reasons, the fusing at d.c. supply is based on the number of included I/O subracks.
Here, out of necessity, an almost “worst case” view is taken.
