Avoid dropping any miscellaneous objects (especially metal scraps) in the maintenance
compartment. Clean up them immediately if any.
Terminating a Ground Cable with an OT Terminal
Strip the ground cable.
A: OT terminal
B: ground cable
C: exposed cable conductor
L1: length of the exposed cable
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.

Hole 1 (+): Insert a brown (black) 0 V ground cable into it.
Ensure that the cable section inserted into each hole is

connected securely.
If the wires slide outward or are exposed outside the holes, remove
the cables and cut the wires. Then strip and connect the cables again.
Fit the exposed cable into the OT terminal.
Ensure that the cable conductor does not protrude
more than 2 mm from the OT terminal.
