IMPORTANT: Before proceeding with the connection between terminals and connection
busbars:
• make sure that the contact surfaces of the busbars are free of burrs, dents, traces of
rusting, dust or traces of grease.
• make sure, if aluminium busbars are used, than these are tin plated in the contact
areas.
• make sure that the busbars do not exert forces in any direction on the terminal.
• for tightening use M10 screws with resistance class 8.8 equipped with spring washers
and lock them with a torque of 45 Nm - 400 lb in.
