the high current required. A minimum size of 25 mm
recommended. Rubber insulated welding cable is convenient to work
with because of its flexibility.
Connections to the controller bus bars should be made with lugs
suitable for the cable used, fastened by M8 (5/16") bolts and nuts. When
tightening the bolts, two opposing wrenches should be used. Failure
to use the double-wrench technique could cause undue strain to be placed
on the internal connections, and could also result in cracked seals around
the bus bars.
