Mounting the adapter unit
For the supply of a complete drive unit (gear unit + motor + frequency inverter) the SK 200E frequency
inverter and the SK T14-... adapter unit are always completely assembled and tested. The adapter unit can
also be ordered separately for subsequent mounting on an existing motor or to replace a different motor-
mounted frequency inverter.
NOTE
However, the IP66 compliant SK 200E must be installed by NORD, as special measures must
be implemented. IP66 components retrofitted on site cannot ensure that this protection class is
guaranteed.
The “Adapter unit SK T14” includes the following components:
• Cast housing, seal (already glued in) and insulation plate
• Power terminal block, corresponding mains connection
• Control terminal block, corresponding SK 200E version
• Screw kit, for mounting on the motor and the terminal bars
• Pre-fabricated cable for motor and PTC connections
Procedures:
1. If necessary, remove the original terminal box from the NORD motor, so that only the base of the
terminal box and the terminal strip remain.
2. Set the bridges for the correct motor circuit and connect the pre-fabricated cables for motor and PTC
connections to the respective connection points on the motor.
3. Mount the cast housing on the terminal box base using the existing screws and seal. Position the cast
housing with the dome facing the A-side of the motor. Check the adaptability for different motor
manufacturers.
4. Attach the insulating plate above the terminal strip. Screw on the power terminal block above this using
the 2 M4x8 screws and the plastic washers.
5. Connect the motor cables U, V, W to the power terminal block and the PTC cable TF+, TF- to the control
terminal block 38, 39.
