2.1.1 Work procedures for motor installation
1. If necessary, remove the original terminal box from the NORD motor, so that only the base of the terminal
box and the motor terminal strip remain.
2. Set the bridges for the correct motor circuit at the motor terminal strip, and connect the pre-fabricated
cables for motor and PTC connections to the respective connection points on the motor.
3. Remove the casing cover from the SK 1x0E. To do this, undo 4
fastening screws and then remove the casing cover vertically from
above.
4. Fit the casing of the SK 1x0E to the terminal box base of the NORD motor using the existing screws and
seal as well as the provided toothed contact washers. When doing this, align the casing so that the rounded
side is facing the direction of the A bearing cover of the motor. Carry out mechanical adaptation using the
"Adapter kit" (

Section 2.1.1.1 "Adapters for different motors"). With motors made by other manufacturers,
it must be checked whether they can be attached.
If necessary, the plastic cover (1) for the electronics must be carefully removed in order to make the screw
fastenings to the base of the terminal box. Proceed with extreme caution when doing this to avoid damage
to the exposed PCBs.
5. Make electrical connections. For the cable gland of the connecting cable, appropriate screwed connections
for cable cross-section must be used.
6. Re-attach the casing cover. In order to ensure that the protection class for the device is achieved, care must
be taken that all the fastening screws of the housing cover are tightened crosswise, gradually and with the
torque specified in the table below.
The cable glands that are used must at least correspond to the protection class of the device.
Size SK 1x0E Screw size Tightening torque
Size 1 M5 x 25 3.5 Nm ± 20 %
Size 2 M5 x 25 3.5 Nm ± 20 %
