Primary terminals connection
Bus bars and cables shall be connected with the primary terminals of ISM mechanically in a stress-free manner.
No pressure, tension or torsion shall act on the ISM.
Both contact arms and rectangular bars can be connected to terminals. The level of fastening depends upon external
connection. To fasten a contact arm or a bar, nuts or heads of bolts and mounting brackets shall be placed into
vertical slots of the terminals, as shown on figures 21, 22, 23.
