2. As shown in the figure, peel off the shields from the
rubber and wire of the power cable.
• Peel off 20 mm of cable shields from the pre-
installed tube.
CAUTION

7. After tube contraction work is completed, wrap it with
the insulation tape to finish.
CAUTION
• Make sure that the connection parts are not
exposed to outside.
• Be sure to use insulation tape and a contraction
