2.1 Installation and assembly
NORDAC SK 200E frequency inverters are available in various sizes depending on their output. Connection
of the SK 200E to the motor or the wall-mounting unit is made by means of the suitable size of connection
unit SK TI4-… The frequency inverter is mounted by means of integrated plug contacts.
The devices require adequate ventilation to protect against overheating. For further details, please refer to
Section 8 “Technical Data”.
Motor-mounted version: Here, the ventilation of the motor is integrated into the cooling concept of the FI.
Mounting must therefore always be carried out as shown in the illustration. For permanently low motor
speeds and self-ventilated motors, a reduction in power similar to the wall-mounted version must be taken
into account.
Wall-mounted version: In continuous operation (S1), mounting away from the motor causes a reduction in
the power of the FI by one power level. This means that relative to the motor, the FI must be selected one
power level larger.
NOTE
For further details of the power reduction and the possible ambient temperatures, please
refer to the technical data in Section 7.
