4.7 Applicable standards

VDE 0106, Part 100
Arrangement of operation elements in the vicinity of dangerous contact parts.
VDE 0110, Part 1
Isolation coordination for electrical equipment in low-voltage power systems.
Allowable degree of fouling 2 for modules and power section.
Only non-conductive fouling may occur. Condensation is excluded, since the components are
certified for humidity rating F.

IEC 68-2-6 for severity class 12

4.8 Fuses and reactors

The phase fuses specified are used to protect the power semiconductor devices. The commutating
reactors recommended guarantee conformance with VDE Specifications as regards to reaction on
the system, and can be matched to the relevant machine rating.
The machine manufacturer must be consulted before choosing the smoothing reactor required in
the armature circuit.
The printed-circuit board of the 5 and 12 A units is prepared for the retrofitting of fuse holders with
field fuses (F201, F202). If necessary, holders for 5 x 30 mm miniature fuses (500V) can be
soldered in. In this case, the R302 and R303 bridging resistances (0 ohms) must be removed.
Converters in special design 6RA22
resistances removed.
An F200 (0.1 A M) miniature fuse protects the line transformer in the unit.

Two phase fuses (and/or one fuse if there is a connection between L1 and N), a commutating
reactor and a smoothing reactor are required per unit.
