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)
Either cable lug, not provided (R5) or cable clamp (R6…R9) is used for grounding.
Note: For the tightening torques of the grounding terminals, see sections Connection
procedure, frames R1…R4 (page 174), Connection procedure, frame R5 (page 178) and
Connection procedure, frames R6…R9 (page 182).
