Hole 2 (-): Insert a blue -48 V cable into
it.
Ensure that the cable section inserted into each hole is
at least 11 mm in length.
Hole 1 (+): Insert a brown (black) 0 V ground cable into it.

Insert the power cables.
Push the cable locking latches on both sides back. Slightly pull the power cables to check whether they are
connected securely.
Use a screwdriver to poke the cable locking latches out.

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.
Terminating Power Cables with a Tool-Less DC Power Connector
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.
