5.8.2 Connection of motor cables
Figure 5-8: Motor controller (the shown motor controller is
the AC-34 but same connections exist on the other motor
controllers AC-36 and 38)
CAUTION!
Motor cables must not be as short as
possible to avoid EMC!
Connections must be preserved with acid-
free Vaseline.
To connect the motor cables and motor sensor cable,
follow these steps:
The motor cables are already fixed to the motor.
1. Remove the metal cover from the motor controller by
removing the screws marked [x], [y] and [z] in Figure ,
on both sides of the controller.
2. Pull the three cables through the corresponding holes
at the front of the controller. Make sure that the U, V
and W cables are placed in the correct location.
3. Connect the three motor cables labeled [U, V, W] onto
the correspondingly marked connections on the motor
controller (see Figure 5-8). Install the cables using the
supplied M8 bolts and tighten them with 9.6 ± 0.9 Nm.
Use a torque wrench.
4. Close the cover carefully and tighten the screws.
The motor sensor cable is already connected to the motor
controller.
5. Connect the motor direction
(4P)
and temp sensor
(2P)
cable from the motor controller to the motor with
the preassembled cable with 2 x IP 66 connector
6. After you close the bipolar separate cable to the heat
pump.
