When you are skillful, you can determine L1
based on the length of the OT terminal lug.
When striping off the insulation layer of the
ground cable, take care not to damage or nick
the metal conductor of the cable.
Ensure that the cable conductor does not protrude
more than 2 mm from the OT terminal.
The crimping impression may differ depending
on the crimping tool used.
