Fuses
AC fuses
There must always be the main AC fuses in the supply unit. If there are parallel modules
after the main AC fuses, there must also be separate module-specific AC fuses for each
module. For the AC fuse types and ordering codes, see section
the locations of the AC fuses in the main circuit, see section
page 22.
We recommend forced cooling for the AC fuses to keep the fuse temperature under
100 °C (212 °F).
•
When the AC fuses are located in the module cubicle, the cooling fan of the module
cools also the fuses.
•
When located in another cabinet (example, in incoming cubicle), use an extra fan.
Install the fan in such a way that it directly cools the fuses.
We also recommend that you monitor the cooling fan status or fuse temperature.
