Rotary Light Dimmer

Installation Instructions

Light dimmers as with all elctrical appliances should be installed by suitably qualified personel.

- Ensure that you have selected the correct dimmer before installation.
- Calculate the total load by adding up the wattage of all the lights to be dimmed.
- If the lights are of the low voltage type, do not exceed the inductive rating of the dimmer, this is the lower rating usually about 25% less than the resistive rating.
- The total load must not be greater than the rating of the dimmer.
- Also ensure that the total load is at least 10% of the rating of the dimmer.
- For the best operation and longest life, the load on the dimmer should be between 30% and 70% of the rated load.

Installing the Dimmer
After ensuring that the power is off, remove the existing light switch, taking note of the existing connections.


Connect the Live wire (usually red) directly to the red wire of the dimmer - do not connect via a switrch as the dimmer has a built in switch.
Connect the load wire (the wire that goes to the light, and is usually red, yellow, blue or orange) to the yellow wire of the dimmer module.

Caution:
- Never connect the dimmer to any earth (green) or neutral (black) wires.
- When used on "low voltage" lights connect the dimmer in series with the live wire on the 230v side of the transformer and NOT the 12v side.

Trouble Shooting

The dimmer gets hot or has a burning smell:
- The dimmer is over-loaded, turn off and re-calculate the load.

The Lights flicker:
-The dimmer is under loaded.
- Replace 40watt bulbs with 60watt bulbs.
- There are electronic transformers that are not suitable for dimming.
_ Electronic transformers must be marked "suitable for dimming".
_Use a vottage stabaliser with electronic transformers that are noisy or unstable (flicker).

Our dimmers have been tested for complience with S.A.B.S. regulations regarding electro-magnetic interference levels.
