8. Connect the phase conductors of the motor wiring to terminals T1/U, T2/V and T3/W.
9. If you use a brake resistor, connect the brake resistor conductors to terminals R-
and UDC+.
10. Make sure that the R- and UDC+ terminal screws are tightened. Do this step also
if you do not connect cables to the terminals.
11. Connect the protective earth (ground) conductor(s) of the input power wiring to the
grounding terminal.
12. Connect the phase conductors of the input power wiring 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.
