The following connection type is recommended when connecting a cable lug (4) to a
busbar:
•
Spring washer (1) and flat washer (2) on each side of the busbar (3).
Other washers can be used, provided they maintain the required contact pressure.

•
Use cable lugs suitable for M12 bolts. The required tightening torque is 40 Nm.
Lubrication
•
If stainless steel bolts and nuts are used, lubricate the thread and head contact
surface of the bolt using recommended pasts, e.g. Molykote D paste.
Note: If a coated nut (e.g. with bonded molybdenum-disulfide [MoS
the connection does not have to be lubricated.
Tightening torque
•
Tighten bolted connections with bolts of sizes M10 and greater with the recommended
nominal torque for the bolt size used.
