1. Do not use aluminum cable with frame sizes R1…R4.
Power Terminal Considerations – R6 Frame Size
Warning! For R6 power terminals, if
compression lugs are supplied, they can only
be used for wire sizes that are 95 mm
2
(3/0
AWG) or larger. Smaller wires will loosen and
may damage the drive, and require ring lugs as
described below.
Ring Lugs
On the R6 frame size, if the cable size used is less
than 95 mm
2
(3/0 AWG) or if no compression lugs
are supplied, use ring lugs according to the following procedure.
1. Select appropriate ring lugs from the following table.
2. Attach the supplied terminal lugs to the drive end of the cables.
3. Isolate the ends of the ring lugs with insulating tape or shrink tubing.
4. Attach terminal lug to the drive.
