may damage the screw thread.
If specified terminal lugs other than those in not recommended dimensions are
used, terminal screws may not be tightened. In such a case, bend each solderless
terminal lug in advance and then conduct wiring. If the terminal screw is forcibly
tightened, it may be damaged.
Up to two solderless terminal lugs can be connected to one terminal screw.
However, in this case, reinforced insulation cannot be used.
Caution for the terminal cover usage:
If each solderless terminal lug touches the terminal cover, remove each projection
