￭ Connection procedure for frames R1 to R3
1. Undo the mounting screws at the sides of the front cover.
2. Remove the cover by sliding it forward.
3. Attach the residual voltage warning sticker in the local language to the control panel
mounting platform.
4. Remove the rubber grommets from the entry plate for the cables to be connected.
5. IP21 drives: Attach the cable connectors (included in the delivery in a plastic bag)
to the cable entry plate holes.
6. Prepare the input power and motor cable ends as illustrated in the figure.
Note: Bare shield will be grounded 360 degrees.
7. IP21 drives: Ground the shields 360 degrees in the connectors by tightening the
connector onto the stripped part of the cable. IP55 drives: Tighten the clamps onto
the stripped part of the cables. Mind the sharp edges.
8. Connect the twisted shields of the power cables to the grounding terminals.
9. Connect the additional PE conductor (if used, see page 19) of the input cable to the
grounding terminal.
10. Connect the phase conductors of the input cable to the L1, L2 and L3 terminals and
the phase conductors of the motor cable to the T1/U, T2/V and T3/W terminals.
Connect the brake resistor conductors (if present) to the R+ and R- terminals. Tighten
the screws to the torque given in the figure below.
11. Install the control cable grounding shelf in the cable entry box.
12. Attach the cables outside the drive mechanically.
