For the lead-through plate hole diameters, see chapter Dimensiondrawings 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 theinstallation complies with local laws and regulations.Note: For the tightening torques of the grounding terminals, see sections Connection procedure, framesR1…R4 on page 97, Connection procedure, frame R5 on page 105 and Connection procedure, framesR6…R9 on page 111.
