Connection procedure with conduit
1.
Connect the power cables. ABB recommends symmetrically shielded VFD cable for connecting the motor.
•
Attach the residual voltage warning sticker and remove the covers as instructed in
cable
.
•
Remove the rubber grommets from the conduit plate for the conduit to be connected.
•
Attach the conduit to the drive conduit plate, and to the motor or source of power distribution. Make sure conduit is
correctly bonded at both ends of the conduit. Ensure conductivity of the conduit. Slide the VFD shielded cable or
discrete conductors through the conduit and strip the cable ends.
•
If you use a symmetrically shielded VFD cable, twist the grounding wires together with the cable shield and connect
them to the grounding terminals. Ground the shield 360 degrees at the grounding clamp. If you use discrete
conductors connect the insulated ground conductor to the ground terminal.
•
Connect the input and motor conductors and tighten cable terminals

.
•
Frames R4, R5: Install the EMC shroud separating the input and output cabling if not installed yet.
•
If brake chopper is in use: Connect the brake resistor conductors to the R+ and R- terminals.
•
Reinstall the shroud on the power cable terminals.
2.
Connect the control cables
•
Attach the cable conduits to the drive conduit plate. Make sure conduit is correctly bonded at both ends and that the
conductivity is consistent throughout the conduit. Slide the control cables through the conduit.
•
Cut to suitable length (note the extra length of the grounding conductors) and strip the conductors.
•
Ground the outer shields of all control cables 360 degrees at a grounding clamp.
•
Ground the pair-cable shields to the grounding clamp. Use an unused ground clamp screw. If none available ground
as shown. Leave the other end of the shields unconnected or ground them indirectly via a high-frequency capacitor
with a few nanofarads, eg, 3.3 nF / 630 V.
•
Connect the conductors to the appropriate terminals of the control unit.
•
Wire the optional modules if included in the delivery.
•
Reinstall the front covers as instructed in
