5.5.3.1 Earthing the Front Cover
The earth lead (E) must be connected to the back box
prior to fitting the upper extension chassis (F) as follows:
1
Connect one end of the earth lead (E) to the blade
terminal located on the right-hand side of the back
box (not shown).
2
Rest the earth lead on the top surface of the U-shaped
channel (G).
3
Fit the upper zone extension and secure.
4
When offering the cover to the back box for fitting
(see below), first locate the free end of the earth lead
on the front cover’s earth blade terminal.
5.5.3.2 Fitting the Front Cover
When the zone extension chassis have been fitted and
all wiring has been connected, fit the front cover as
follows:
1
Offer the cover (H) symmetrically and correctly
orientated to the front of the back box.
Note:
To make sure the cover is correctly orientated, the
top of the cover has a ledge (I) which locates on
the flange (J).
2
Use a 4mm hexagonal socket key to tighten each
hexagonal socket-headed M6 screw (K).
3
To remove the cover, use the 4mm socket key to
unscrew the M6 screw (K).
CAUTION:
Make sure the cover is supported when
releasing the last fastener.
5.5.3.3 Label Inserts
Each extension chassis is provided with a vertical slot
behind the fascia to allow a label (M) to be inserted. Insert
the label as follows:
1
With the label correctly orientated, find the slot in the
top edge of the fascia and insert one corner to start.
2
Once the end has been inserted in the slot, straighten
the label and push in until all windows in the fascia
display the label text. A small amount of the label will
protrude above the fascia.
