ABB ACS380 User Manual

8. If you use a brake resistor, connect the brake resistor cable to terminals R- and
UDC+. Use shielded cable and ground the shield under the grounding clamp for
360-degree grounding.
9. Make sure that the R- and UDC+ terminal screws are tightened. Do this step also
if you do not connect cables to the terminals.
10. Strip the input power cable.
11. If the input power cable has a shield, ground the shield under the clamp for
360-degree grounding. Twist the shield also into a bundle, mark it with yellow-green
insulation tape, install a cable lug, and connect it to the grounding terminal.
12. Connect the protective earth (ground) conductor(s) of the input power cable to the
grounding terminal.
13. Connect the phase conductors of the input power cable to the drive as follows:
• 1-phase drives: connect the phase and neutral conductors to terminals L1 and
L2. For example, connect phase to L1 and neutral to L2.
• 3-phase drives: connect the phase conductors to terminals L1, L2, and L3.
14. Mechanically attach all of the cables on the outside of the drive.
Connecting the control cables
Before you connect the control cables, make sure that all option modules are installed.
