Due to insufficient number of terminal bolt connections for required amount of cables, the cabinet must be
equipped with an external flexible cable connection block at both mains and motor ends if stiff cable type is
used.
Data in Italic refer to drives with 12-pulse supply.
Units with 6-pulse supply
Note that all other sizes have 3 input terminals except for size CH74, which has 9 input terminals.
CH74 cables must be connected symmetrically between 3 parallel connected rectifiers in each
phase.
Units with 12-pulse supply
12-pulse supply can be used with drives of sizes CH72 and CH74. The number of input terminals for
both is 6.
If 12-pulse supply is used, pay also attention to the fuse selection, see page 82 and page 83.
See the tightening torques of bolts in Table 40.
