Cable lug connection to the connection box (example only, the connection box may look different)
9. Screw the cable gland to the connection box as shown in the Figure above. Tighten the cable gland
from the body of the gland. See Chapter Tightening torques .
Tighten from the body of the cable gland with the correct torque. Then tighten the cap of
the cable gland manually, but so that the insulation does not come out of the joint.
10. Tighten the cable lug. Use tightening torque of 15 Nm.
11. Repeat the procedure to the other cables and connection boxes.
12. Check that the phase connections order in the connection box is correct, that is, the corresponding
phases between the inverter and the machine are connected (U, V, W correspond to the L1, L2, L3
phases).
13. Close the connection box. Tighten the connection box cover screws. See Chapter Tightening
torques . Use thread locking compound that makes it possible to remove the screws. (For example
Loctite 221).
Check the power cable shield grounding, see Chapter Grounding connections .
Low voltage connections
Plug the unused socket holes of the low voltage connector with suitable plugs:
•
DEUTSCH 0413-003-1605 (size 16)
•
DEUTSCH 0413-204-2005 (size 20)
See more information and instructions about DEUTSCH connectors at https://

The electric machine has a connector or a connection box which is used to read out in-built temperature
and rotation sensor (resolver) data from the electric machine. The temperature data comes from PT100
sensors in the stator windings and in some cases in the bearings. The rating plate has the information
about the options of the electric machine: different options add sensors, and some electric machines do
not have all the sensors. For more information about the options, refer to Chapter
Product naming
convention on page 5.
