Connection procedure
WARNING!
Obey the safety instructions of the drive. If you ignore them, injury or
death, or damage to the equipment can occur. If you are not a qualified
electrical professional, do not do installation, commissioning or
maintenance work.
Refer to Terminal data for the power cables (page 119) for the tightening torques.
1. Do the steps in section Electrical safety precautions (page 16) before you start
the work.
2. Attach the residual voltage warning sticker in the local language to the drive.
3. Install the conduits, and attach them to the cable entry plate of the enclosure
that the drive is installed in.
4. Make sure that the conduit is correctly grounded at the cable entry.
5. Strip the conductor ends and pull the conductors through the conduits.
6. Connect the protective earth (ground) conductor of the motor wiring to the
grounding terminal.
7. Connect the phase conductors of the motor wiring to terminals T1/U, T2/V
and T3/W.
8. Frames R2…R4: If you use a brake resistor, connect the brake resistor
conductors to terminals R- and UDC+.
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. Connect the protective earth (ground) conductor(s) of the input power wiring
to the grounding terminal.
11. 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.
12. Connect the other ends of the conductors.
