Earthing, Power, and
Motor Cable Connections
1. Lead the power cable through the INPUT cable entry, and the
motor cable through the OUTPUT entry into the unit. Frame R7:
Remove the rubber grommets from the INPUT and OUTPUT
entries and cut them to adequate diameter for the power and the
motor cable. To ensure proper sealing cut along the diameter
marking which corresponds to the cable diameter.
2. Connect the phase conductors of the power cable to the U1, V1
and W1 terminals and the phase conductors of the motor cable to
the U2, V2 and W2 terminals.
3. Connect the twisted screen of the power cable to the grounding
terminal. Perform the same with the motor cable screen.
Connect the additional PE conductors (if present) of the power and
motor cables to the grounding terminal. Connect the separate PE
conductor (if used) to the grounding terminal.
Control Cable
Connections
1. Lead the cable inside the unit through the SIGN entry.
Connect the conductor in appropriate terminal at the NIOC/NIOCP
board (A2, refer
Appendix A and Firmware Manual ) and tighten screw
to secure connection. Connect the twisted screen (grounding wires) to
1) Alternative to earthing of the ACx 601 and
the motor through the cable screen.
Note: Connecting the fourth conductor of
the motor cable at the motor end increases
bearing currents, thus causing extra wear.
2) Used if the conductivity of the cable screen
is < 50 % of the conductivity of the phase
conductor.
For minimum radio frequency interference
(RFI) at the motor end, earth the cable
screen 360 degrees at the lead-through of
the motor terminal box or earth the cable by
twisting the screen (flattened width > 1/5 ·
length).
Earth the other end of the mains cable at
the distribution board.
Recommended earthing, mains and motor cable connections are presented
below. See
