Temperature rating of cables: Enclosure ambient tempe 35 ºC or more
Note: Use cables capable of supplying current required by respective pieces of equipment with low voltage drop.
Note: Ensure to secure the minimum bending radius of the cable. The minimum bending radius is either the value shown in the cable
manufacturer’s specifications or six-fold of the cable conductor diameter, whichever is bigger should be applied.

Solderless (crimp-on) lug terminal processing
Use solderless lugs for power cables (see Figure). Use solderless (crimp-on) terminals with
insulating cover, which have low contact resistance little aging.

CAUTION
• Always use solderless lugs with insulating covering.
• Always use solderless lugs and crimp-on tool manufactured by the same manufacturer.
• The crimp-on tool must be matched to the wire thickness.
