Tap-off Unit Installation
Phase sequence shall be made according to field application require-
ments and construction drawings.
Remove the bolts on the busduct socket cover and open the socket
protection cover. (See Figure 16).
Open the tap-off unit door. Open Lock Anchor A and B. Then, aim at the
slot in the socket, and insert in the unit smoothly until the unit bottom is
closely contacted with the cover (PE pin shall contact the housing first to
ensure safe grounding). Move the two lock anchors of A and B inwards
to lock up busduct cover (Figure 19). When Lock Anchor A and B are in
place, close the unit door and tighten the bolts.
Note:
When Lock Anchor A and B are in place, it means they are vertical
to the cover plate and in parallel to the side of the tap-off unit.
