Power Cable Connection Procedure - ABB ACS880-04 Hardware Manual

7 External brake resistor (optional, see page 233).
8 Common mode filter (optional, see page 65).
9 du/dt filter (optional, see page 239).
10 The drive module frame must be connected to the cabinet frame. See section
grounding inside the cabinet
97.
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.

Power cable connection procedure


WARNING! Obey the safety instructions in chapter
ignore them, injury or death, or damage to the equipment can occur.
1. Run the motor cables from the motor to the cabinet. Ground the cable shields 360° at
the lead-through 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 busbar of the output power
cabling panel.
3. Connect the phase conductors of the motor cables to terminals T1/U2, T2/V2 and
T3/W2 of the output cabling panel. For the tightening torques, see page 184.
4. Drive modules with option +D150: Run the power cables from the brake resistor to the
cabinet. Ground the cable shield (if present) 360° at the lead-through plate. Connect
the conductors to the R+ and R- terminals. For the tightening torques, see page 184.
5. Make sure that all power is disconnected and reconnection is not possible. Use proper
safe disconnect procedures according to local codes.
6. Run the input cables from the supply source to the cabinet. Ground the cable shields
360° at the lead-through plate.
7. Twist the cable shields of the input cables into bundles and connect them and any
separate ground conductors or cables to grounding busbar of the input cabling panel.
8. Connect the phase conductors of the input cables to terminals L1/U1, L2/V1 and
L3/W1 of the input cabling panel. For the tightening torques, see page 184.
