is an important factor for the functional reliability and safety as well as the useful life of the whole installation. A maximum of three components can be connected in parallel (1 basic unit + 2 parallel units).

From product status A2 and onwards, rectifier units can be ordered without semiconductor fuses - option L32 (In the case of product status 1, option L32 means that semiconductor fuses are built in). External cable- protection devices, however, do not provide protection for the thyristors.
The rectifier/regenerative units are generally supplied with semiconductor fuses. It is not permissible to operate them without semiconductor fuses.
The electronic p.c.b's must be supplied with power from an external 24 power supply system (1 A for basic unit, 0.3 A for every other unit connected in parallel).
For the changes in the MRPD setting (setting of the type) as well as other information and warnings, see the operating instructions for the
