The converters should be fused on the line side with fuses according to Table 0.1. In order to reduce noise and
to limit the harmonics fed back into the supply a 2% commutating reactor should be used to connect the
converter to the supply. Refer to Table 3.1 for the Order Nos. for the fuses and the line commutating reactors.
To maintain the radio interference suppression regulations, refer to the Instruction Manual, Part 2, Section
„Measures to maintain the radio interference suppression regulations".
The position of the connecting terminals can be seen in the dimension drawings (+ Section 2.4).
Line connection:
Motor connection:

Protective conductor connection:

Connections must be established using cable lugs with bolts according to Table 3.2.
Converters type of construction H: The busbars of the motor connection are rotated through 90 °.
Due to the 230 V fan a transformer is integrated into the converters. The terminals on the primary side must be
connected corresponding to the rated input voltage.
Depending on the motor insulation strength and the length of the motor feeder cable, it may be necessary to
install one of the following options between the motor and the converter:
♦ Output reactor
♦ dv/dt-filter
♦ Sinusoidal filter
