Lug assembly: 1234 models
Five aluminum M6 terminals are provided. Lugs should be installed as follows,
using M6 bolts sized to provide proper engagement (see diagram):
• Place the lug on top of the aluminum terminal, followed by
a high-load safety washer with its convex side on top. The
washer should be a

• If two lugs are used on the same terminal, stack them so the
lug carrying the least current is on top.
• Tighten the assembly to 10.2 ±1.1 N·m (90 ±10 in-lbs).
