2.1.3 Installation of the SK 200E
In order to carry out the electrical connection of the SK 200E, this may need to be removed from the
connection unit. To do this, remove the 4 fastening screws, so that the frequency inverter can be lifted off
vertically.
After the electrical connection of the power cables has been made, the frequency inverter can be replaced.
This must be carried out in a vertical direction relative to the connection unit without tilting. The PE cinch
plug can be used in order to ensure correct guidance.
In order to achieve the maximum protection class
IP55/IP66, care must be taken that all frequency
inverter fixing screws are gradually tightened
diametrically oppositely, with the torques stated in
the table below.
For the cable gland of the connecting cable,
appropriate screwed connections for cable cross-
section must be used.
Dissipation of heat generated by the inverter occurs
by means of convection. This is assisted by the
airflow of the motor. Because of this, a reduction in
power for unventilated motors or wall-mounted
devices must be taken into account (for further
details see Section 7, Technical Data).
Heat dissipation must not be hindered by severe
contamination.
