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 transformer 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 this
transformer is t 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 Standard
and is intended for normal domestic service. Use
of this transformer for any other than its intended
purpose, may result in a foreshortened working life.
Switch o the mains before commencing
installation and remove the appropriate circuit fuse.
When working at heights, please use a suitable
platform.
Do not overload the transformer; check that the
total load does not exceed the maximum marked
on the transformer.
Disconnect the transformer from the electrical
supply before ash or high voltage testing.
Suitable for indoor use only.
This product is suitable for installation on surfaces
with normal ammability e.g. wood, plasterboard,
masonry. It is not suitable for use on highly
ammable surfaces (e.g. polystyrene, textiles).
Before making xing hole(s), check that there are no
obstructions hidden beneath the mounting surface
such as pipes or cables.
The chosen location of your new transformer should
allow for the product to be securely mounted and
safely connected to the mains supply.
Do not cover the transformer with any insulating
materials.
Ensure that the transformer will be accessible after
installation for maintenance or replacement.
Do not attach to surfaces which are damp, freshly
painted or otherwise electrically conductive (e.g.
metallic surfaces).
If the location of your new transformer requires
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).
This product is designed for permanent connection
to xed wiring: this should be either a suitable
circuit (protected with a 5 or 6 Amp MCB or fuse)
or a fused spur (with a 3 Amp fuse) via a fused
connection unit. We recommend that the supply
incorporates a switch for ease of operation.
Make connections to the electrical supply in
accordance with the following code:
Live - Brown or Red
Neutral - Blue or Black
This transformer is double insulated, and the
transformer output is SELV (Safety Extra Low
Voltage). Do not connect any part to earth.
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. Wrap loose terminal blocks well with
insulating tape.
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 specied in the Wiring Regulations
(BS7671) referred to in the Building Regulations.

1) Choose the location for your new transformer
giving consideration to each of the points opposite.

3) Remove the xing kit.
4) Using the rear of the case as a template, mark the

5) Secure the transformer in place using the xings
supplied. If the xings are not appropriate for your
installation use suitable alternatives.
6) Make the connections to your bell and/or bell push
according to the instructions supplied with them.
Check the Voltage required by your bell/sounder
