Power cable connection procedure
WARNING! Obey the safety instructions in chapter Safety instructions. If you
ignore them, injury or death, or damage to the equipment can occur.
WARNING! Apply grease to stripped aluminum conductors before attaching them
to non-coated aluminum cable lugs. Obey the grease manufacturer.’s instructions.
Aluminum-aluminum contact can cause oxidation in the contact surfaces
1. Run the motor cables from the motor to the cabinet. Ground the cable shields 360° at
the entry plate.
2. Twist the cable shields of the motor cables into bundles and connect them and any
separate ground conductors or cables to the ground terminal of the drive module or to
the cabinet ground bar.
3. Connect the phase conductors of the motor cables to terminals T1/U2, T2/V2 and
T3/W2 of the drive module. For the tightening torques, see page 193.
4. Make sure that all power is disconnected and reconnection is not possible. Use proper
safe disconnect procedures according to local codes.
5. Run the input cables from the supply source to the cabinet. Ground the cable shields
360° at the entry plate.
6. Twist the cable shields of the input cables into bundles and connect them and any
separate ground conductors or cables to the drive module ground terminal or to the
cabinet PE busbar.
7. Connect the phase conductors of the input cables to terminals L1/U1, L2/V1 and
L3/W1 of the drive module. For the tightening torques, see page 193.
8. Brake chopper option:
Run the power cables from the brake chopper to the cabinet.
Ground the cable shield (if present) 360° at the entry plate. Connect the conductors to
the UDC+ and UDC- terminals. For the tightening torques, see page 193.
Connecting the control cables and installing option
6 Common mode filter (optional, see page 59)
7du/dt filter (optional, see page 239)
8 EMC filter (option +E202, see page 93)
9 The drive module frame must be connected to the cabinet frame. See section Arranging the
grounding inside the cabinet on page 48 and Alternatives for grounding the drive module on page
91.
10 Brake chopper
11 Brake resistors
Note:
If there is a symmetrically constructed grounding conductor in the motor cable in addition to the conductive
shield, connect the grounding conductor to the grounding terminal at the drive and motor ends.
Do not use an asymmetrically constructed motor cable. Connecting its fourth conductor at the motor end
increases bearing currents and causes extra wear.
