drive unit in place on the moulding and carefully insert the eight M6 socket head
machine screws. It is best to start these bolts into their threads by hand, to avoid

terminals observing the correct polarity (brown positive and blue negative) and
then replace the access door.
X3-DF/X3-DFSP enclosure - Removing the HF Array
1. Lie the enclosure on its back. Remove the Pozidrive screws (in the front and down
each side) that secure the grille, and carefully remove the grille.
2. Remove the eight M6 countersunk machine screws securing the HF array
waveguide. Note that the four outer bolts are shorter than the four inner bolts.
Once the bolts are removed, gently lift the X3 waveguide moulding out of its
location.
3. Once the waveguide is removed, disconnect the cable assembly.
4. To reconnect the cables, note that the wiring orientation is critical. The X3 Array
label should point upwards when the box is upright and also the angled sides of
the waveguide will follow the cabinet angles. The cables have the correct length
for each drive unit. Ensure polarity is also correct (white positive, yellow negative).
5. To re-instate the HF array, position in place and gently press the moulding down
until it rests on its mounting flange. Ensure the cables are not caught up when
you reinstall. Replace the eight M6 bolts and retighten.
