READ THIS FIRST:
Check the pack and make sure you have all of the
parts listed on the front of this booklet. If not,
contact the outlet where you bought this product.
This time delay switch must be installed by a
competent person in accordance with the Building
Regulations making reference to the current edition
of the IEE Wiring Regulations (BS7671).
As the buyer, installer and/or user of this product it
is your own responsibility to ensure that it is fit for
the purpose for which you have intended it. Eterna
Lighting cannot accept any liability for loss, damage
or premature failure resulting from inappropriate
use.
This product is designed and constructed according
to the principles of the appropriate British Standards
and is intended for normal service.
Switch off the mains before commencing installation
and remove the appropriate circuit fuse.
Do not overload the switch; check that the total
wattage and start up surge current (if any) of the
connect load does not exceed the maximum
specified.
Disconnect the switch from the electrical supply
before flash or high voltage testing.
Suitable for indoor and outdoor use.
Before making fixing hole(s), check that there are no
obstructions hidden beneath the mounting surface
such as pipes or cables. If your switch is part of the
provision of a new electrical supply, the supply
must conform with the requirements of the Building
Regulations making reference to the current edition
of the IEE Wiring Regulations (BS7671).
Make connections to the electrical supply in
accordance with the following code:
Live - Brown or Red
Neutral - Blue or Black
NOTE:
This is not a two-wire system and requires
neutral connection.
When making connections, ensure that the terminals
are tightened securely and that no strands of wire
protrude. Check that the terminals are tightened
onto the bared conductors and not onto any
insulation.
This switch is double insulated; do not connect any
part to earth.
You are advised at every stage of your installation to
double-check any electrical connections you have
made. After you have completed your installation
there are electrical tests that should be carried out:
these tests are specified in the Wiring Regulations
(BS7671) referred to in the Building Regulations
LOAD SPECIFICATION:
Incandescent lighting loads - 16A maximum.
Fluorescent lighting loads - 6A maximum.
Compact fluorescent/low energy lighting loads - 3A
maximum.
Low voltage lighting loads - 3A maximum.
LED load 300W.
NOTE:
a maximum of 6 fluorescent light fittings is
recommended with total power factor correction
capacitance not exceeding 40μf.
Fans and ventilation equipment – 3A maximum.
SON light fittings must be switched via a contactor
or other external relay. If you are using this switch to
control magnetic switch start fluorescent fittings and
your light fittings strike inconsistently, a power factor
correction capacitor may be required. If your light
fitting flickers or fails to turn off correctly, this is most
likely to be due to incorrect or missing power factor
correction.
Check with the manufacturer of the light fitting and/
or supplier of power factor correction capacitors for
the exact specification required for your installation.
A minimum of 1μF for each fitting may be connected.
INSTALLATION:
01. Choose the location for your new switch
according to the conditions above.
02. Undo the large screws in each corner of the front
of the switch and lift off the lid.
03. Mark the positions of the fixing holes at the
corners of a rectangle 62mm wide x 92mm high.
04. Prepare the fixing holes and insert wall plugs if
necessary.
05. Whether you are intending to use cable glands
or conduit to make your cable entry, you will
need to make hole(s) in the rear half of the case to
accept your chosen fitting.
06. Secure the rear half of the case to the wall using
suitable fixings.
07. Make the electrical connections according to the
colour code on previous page.
08. Set the desired “on” time by combination of dip
switches and the rotary control, see Fig 1. and
table below.
09. Close the switch case and tighten the screws.
Take care not to over-tighten.
10. Restore the mains power and wait 20 seconds for
the switch to stabilise.
11. Activate the switch and check the “on” time.
12. If the time “on” requires further adjustment, turn
of the power at the mains before opening the
switch case. Remember to wait 20s after restoring
the power before activating the switch again.
TRIGGER FUNCTION:
The timer can be triggered by applying a live
connection to the “trigger” terminal. This can be
done using a momentary switch for example, in
lighting applications; or an unswitched link for
applications such as extractor fan over-run.
MULTI-POINT SWITCHING:
For switching the load from multiple locations simply
connect two or more units in parallel.
NOTE:
All switches must share the same power
supply.
