Connection procedure with conduit
1.
Connect the power cables. ABB recommends symmetrically shielded VFD cable for connecting the motor.
•
Remove the covers as instructed in
shroud on the power cable terminals as instructed in
•
Remove the rubber grommets from the conduit plate for the conduit to be connected. If you remove the cable
shelves, reinstall the four screw plugs to avoid moisture exchange through the empty holes.
•
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

2.
Connect the control cables
•
Frame R3: Pull the control panel holder up.
•
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. Route the cable as shown in the figures below.
•
Secure the cables inside the drive mechanically.
•
Ground the pair-cable shields and grounding wire at the grounding terminal
(SCR) of the control unit.
•
Reinstall the front covers as instructed in
