Table 6-3. Motor cable sizes, 525—690V
1)
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. See also
chapter 6.1.3, step 5.
* = Number of bolt connections 2
** = Number of bolt connections 4
*** = Three earthing terminals per mounting plate, see chapter 6.1.6.
**** = Two earthing terminals per mounting plate, see chapter 6.1.6.
See the tightening torques of bolts in Table 6-6.
