1)
Maximum cable diameter accepted. For the lead-through plate hole diameters, see chapter Dimension
drawings on page 203.
2)
Either cable lug (R5, see page 109) or clamp (R6…R9, see page 113) is used for grounding.
3)
Note: Minimum wire size does not necessarily have enough current capability for full load. Make sure the
installation complies with local laws and regulations.
Note: For the tightening torques of the grounding terminals, see sections Connection procedure, frames
R1…R4 on page 97, Connection procedure, frame R5 on page 105 and Connection procedure, frames
R6…R9 on page 111.
