Maximum cable diameter accepted. For the entry plate hole diameters, see chapter Dimension
drawings (page 309).
2)
Note: Minimum wire size does not necessarily have enough current capability for full load. Make sure the
installation complies with local laws and regulations.
3)
Note: Either cable lug (R5, see page 133) or clamp (R6…R9, see page 136) is used for grounding.
Note: For the tightening torques of the grounding terminals, see sections Connection
procedure, frames R1…R4 (page 123), Connection procedure, frame R5 (page 129) and
Connection procedure, frames R6…R9 (page 134).
