Do not turn the body of the gland! By tightening from the cap of the gland the cable is sealed to the cable gland and at
the same time the cable gland is tightened to the connection box with correct torque.
10. Tighten the cable lug. Use tightening torque of 15 Nm.
11. Repeat the procedure to the other cables and connection box.
12. Check that the phase connections order in the connection box is correct, ie. 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).
If you must connect the anti condensation heater, you can leave the connection box open. See
Chapter Anti condensation heater.
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)
The electric machine has a connector which is used to read out in-built temperature and rotation
sensor (resolver) data from the 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 machine: different options add sensors, and some machines do not have all the
sensors that are listed in the table below. For more information about the options, refer to the data
sheet of the electric machine.
