2.3.5 Mounting the adapter unit
The SK 300E frequency inverter and the (SK TI 0/1 (-C) or SK TI 0/2 (-C)) adapter unit are always completely
mounted and tested when a trio drive (gears + motor + frequency inverter) is delivered. The adapter unit can
also be ordered separately for subsequent mounting on an existing motor or to replace an older motor-
mounted trio frequency inverter.
Note
However, the IP66-conform SK 300E must be mounted at NORD as special measures have to be
implemented. IP66 components retrofitted on site cannot ensure that this protection class is
guaranteed.
The module "Adapter unit" (SK TI 0/1 (-C) or SK TI 0/2 (-C)) contains the following components:
• Cast enclosure (dependent on type of adapter unit)
• customer interface unit (circuit board)
• M12 socket with system connector for RS485 interface
• Screw accessories for attaching the customer interface unit
• Pre-fabricated cable for motor and PTC connections
Procedures:
1. Screw the M12 socket into the connection unit in the cast enclosure, ensuring that it is tight.
2. Mount the cast enclosure on the terminal box stub of the NORD motor with the existing screws in place of
the terminal box. Position the cast enclosure with the dome facing the motor A-side. Retain the motor's
terminal block. Check the adaptability for different motor manufacturers.
3. After the bridges for the correct motor circuit are set, connect the pre-fabricated cables for motor
connection and PTC connection to the respective connection points on the motor.
4. After the cables for the motor connection and PTC are connected to the appropriate terminals on the
customer interface unit (pin assignment, see Chap. 2.6.1 ), the customer interface must be mounted with
the screw accessories in the cast enclosure. It must be ensured that the insulation foil lies on the inner side
of the cast enclosure dome. Both tabs must be pointing to the inside of the cast enclosure.
5. Connect the M12 socket system connector to the appropriate slot (see Fig. 2)
