• First check that there are no cracks or damage

to end plug. Slide end plug over bus wire

crimps all the way and push firmly toward mastic.

• Wrap one piece of mastic around open end of end plug so

half of width covers end of plug and half covers cables.

• Apply second piece of mastic like the first one to

completely cover end of plug. Press mastic pieces

together and into plug and wire mastic pieces.

• Slide in the 5 inch heat shrink tube and align it with the

flange of end plug, then start heating by a heat gun

from the end plug toward the cables.

• Apply heat with heat gun or torch for at least 5 minutes or until

tubing is completely shrunk. Start from end plug towards cables.

Ensure heat shrink is completely shrunk in each section,

especially around mastic.

• Preferably apply heat in well ventilated area or outdoors.

• Be careful not to burn or damage cable jacket, heat shrink tubing,

or end plug.

• The edge of the heat shrink tube may shrink and have a gap

with the ange of end plug which is acceptable.

CAUTION: To avoid burns allow heated sections to

cool before touching.
