Installation of the motor starter

The housing cover must first be removed in order to make the electrical connections to the SK 1x5E. To do
this, unscrew the 4 fastening screws, so that the housing cover can be removed upwards.

After the electrical connections of the supply cables have been made, the housing cover can be replaced.

To achieve the maximum protection class IP55/IP66, care must be taken that all the fastening screws of the
housing cover are tightened diagonally, step-by-step and 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.
