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 lead-through plate for the cables to be
connected.
5. IP21 units: Fasten the cable connectors (included in the delivery in a plastic bag)
to the cable lead-through plate holes.
6. Prepare the ends of the input power (a) and motor cables (b) as illustrated in the
figure. Note : Bare shield will be grounded 360 degrees.
7. IP21 units: Ground the shields 360 degrees in the connectors by tightening the
connector onto the stripped part of the cable. IP55 units: Tighten the clamps onto
the stripped part of the cables.
8. Connect the twisted shields of the power cables to the grounding terminals.
9. Connect the additional PE conductor (if used, see page 15 ) 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. Secure the cables outside the unit mechanically.
Note : The drawings below show an IP21 unit. The IP55 unit looks slightly different.
For US cable conduit installation, see the quick installation guide.
