Assembling DC Power Cables
a
Prepare for the assembly.
a
Prepare the following tools: dual-head bayonet wrench
(22 mm, 24 mm), dual-head bayonet wrench (19 mm, 22
mm), 0#x50 mm Phillips screwdriver, diagonal pliers, and
utility knife.
a
Assemble the cable.
b
Bind a cable tie to the cable, remove the socket and
nut from a connector, and install them on the cable.

Cable tie
The cable tie prevents the socket from slipping down.
Open the wire clip and correctly insert the core wires
to the negative and positive holes.
The negative and positive holes are marked with silk
prints. Correctly insert the core wires to the negative
and positive holes

cable (connected to
wire
the positive terminal)
The filling material beneath
the shield layer is removed.
The filling material beneath
the shield layer is retained.
Retain the filling material beneath the shield layer.
Check the length to remove with the 1:1 peeling indicator.
Tighten the compact screw in the "+" hole, rotate the
connector 180 degrees, and tighten the compact screw
in the "-" hole.
Rotate the connector
180 degrees.
Apply 2 kg of force to pull the cable and check whether
the cable is secured in the connector.
Prepare the socket and shell and apply a force not less
than 1.2 N· m to tighten the socket.
Red rubber ring
When the socket and shell are properly tightened, the
red rubber ring on the connector cannot be seen.
8
Test the DC power cable with a multimeter.
Avoid short-circuits between the positive and negative holes.
Avoid short-circuits between the shell and the positive/negative hole.
A continuity test between the shield layer and the metal shell is successful.
A continuity test between the core wire and its corresponding hole is successful.
23
Close the wire clip and tighten the screw to compact
the shield layer.
Prepare the nut and socket and apply a force not less
than 1.2 N· m to tighten the nut.
