PLEASE READ THESE INSTRUCTIONS CAREFULLY BEFORE INSTALLATION
LEAVE A COPY FOR THE USER / MAINTENANCE ENGINEER FOR FUTURE REFERENCE

WARNING

This product should be installed by a competent electrician in accordance with these instructions and the latest edition of the National Wiring Regulations. If in
doubt consult a qualified electrician. For use with 12V Class III low voltage luminaires only.

INSTALLATION INSTRUCTIONS

Isolate from the mains supply before installation or maintenance.
The mains supply should be connected to the Primary Input terminals as follows:
Black/Blue - Neutral (terminals marked N) Red/Brown - Live (terminals marked L)
Green/Yellow - Earth (terminal marked
Input Terminals
Dual Live & Neutral terminals allow loop-in
loop-out wiring between transformers. Integrated Earth Terminal allows Earth
continuity in the primary wiring circuit.
The transformer should be sited in a well ventilated position. Do not enclose or cover the transformer with thermal insulating materials. The ambient
temperature during operation must not exceed the ta°C rating of the transformer.
The transformer may be fitted in the same circuit as inductive loads as it has 1.0KV Surge protection in accordance with EN61547
The secondary (output) leads must not exceed 2m in length. Ensure that the wattage of the lamps does not exceed the rating of the transformer.
Figure 1 - CORRECT Installation
Keep the transformer away from direct sources
of heat

DIMMING

I This transformer may be dimmed with most types of standard resistive and
inductive dimmer switches.
Install the dimmer switch on the primary (mains) side of the transformer.
A slight buzzing noise is normal with some types of dimmer switch. An increase in
transformer noise may be experienced when dimmed. The dimmer should be loaded to
at least 75% of its maximum capacity (refer to the dimmer manufacturers' instructions).

RADIO INTERFERENCE

In common with other high frequency converters this product may cause radio interference.
Under certain circumstances interference may be experienced on the medium and long wave radio bands. Please note that these transformers are
suppressed to all relevant EMC standards.
