11. Repeat the procedure to the other cables and connection box (if the machine includes DUAL or TRI
option).
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
Use thread locking compound that makes it possible to remove the screws. (For example
Loctite 221).
If you must connect the anti-condensation heater, you can leave the connection box open. See Chapter
Anti-condensation heater connections
on page 51.
Check the power cable shield grounding, see Chapter
.
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
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
