INSTALLATION INSTRUCTONS
.
a1 -
opening and closing the box
wall mountin
a1 - Remove the rubber seal on the back of the unit, and use it
as a template to mark out the three screw holes (Fig.2).
a2 - Drill the holes (see Fig.5 for drilling details).
a3 - Open the photocell box by sliding the box cover
upwards by about 1 cm and then raise the cover to
access the inside of the box (Fig.3).
a4 - Refit the seal to the back of the box base, then
screw the box to the wall using the screws and plugs
supplied (Fig.5).
a5 - Connect up the terminal block following the wiring
guide given below.
NOTE: If you have to remove photocell card from the
base during wiring, proceed as follows: grip the outer
edges of the card with your thumb and index finger
and then with the index finger of your other hand,
release the retaining tab to free the card. Remove
the card from its mountings (see Fig.4).

handle the card
its circuits and components with care
a6 - When you have completed wiring, refit the card to the
box, as follows. Place the top of the card on the two
mountings and under the upper retaining tab (Fig.6,
inset). Next, lower the plastic mounting and press the
card so that it snaps into position in the box (Fig.6).
