 - Insert the wire.
 - Slowly draw the wire through the pressure seal until it reaches
 its final position.
 - Secure the cable with the cable tie so that the cable will not
 move in the pressure seal.
 - Inject compound (Material N. 09-002) around the base of the
 wires.
 - Clean off surplus sealant with solvent (Material N.11-003). 

R  (4) Wire addition procedure
