JOIN TING<br />

Pair shields <strong>and</strong> the com mon shield are spliced <strong>and</strong><br />

earthed by a cop per con duc tor. It is im por tant in the<br />

joint ing <strong>and</strong> ter mi nal con nec tions that the pair shields are<br />

in su lated one from<br />

the an other, ex cept <strong>for</strong> the com mon ground ing point.<br />

If the joint ing has to be EMC pro tected, the shields have to<br />

be jointed all around i.e. 360°.<br />

SPLIC ING<br />

1. The sheath is stripped. The in ner sheath is pulled<br />

open by the tear- off wire.<br />

2. The pair shield is opened <strong>and</strong> re moved<br />
