2.1.1 Mounting the adapter unit
If a complete drive unit is supplied (gear unit + motor + frequency inverter) the SK 2xxE frequency inverter
and the SK T14-... connection 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
Mounting of an IP66-compliant SK 2xxE must be carried out by NORD as special measures
have to be implemented. IP66 components retrofitted on site cannot ensure that this protection
class is guaranteed.
The “Adapter unit SK TI4” includes the following components:

Cast housing, seal (already glued in) and insulation plate

Power terminal block, corresponding mains connection

Control terminal block, corresponding SK 2xxE 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 of the NORD motor using the existing screws and seal
as well as the enclosed toothed / contact washers. Position the cast housing with the dome facing the A-
side of the motor (looking towards the A bearing cover). 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. (Size 4: 3 M4 cap nuts)
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.
