INTERLOCKING<br />

Thanks to an interlocking system, access to TED transformers and connection interface depend on the earthing and<br />

short circuiting of cabling supplied at origin. This is carried out by an interlocking key together with a Ronis or<br />

Profalux key.<br />

MANHOLE LOCK<br />

The interlocking key can activate a safety<br />

lock N° 7 to release the grid located<br />

inside the inspection manhole between<br />

access covering and transformer.<br />

Only specific parts corresponding to<br />

figures 5, 7 and 8 are listed in <strong>Augier</strong> rates.<br />

LOCKING THE TED TRANSFORMER TERMINALS<br />

If the manhole locking system cannot be used, a terminal locking system can be installed directly on the TED<br />

transformer. The operating principle is the same as that of manhole lock: with a locknut.<br />
