Connect the load to the yellow wire of the dimmer module.
dimmers as with all electrical appliances should be installed
by suitably qualified personnel.
Ensure you have the correct dimmer before installation.
Calculate the 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 lowest rating of the dimmer,
usually about 25% less than the resistive rating.
The total load must mot 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 best operation, and longest life the load on the dimmer should
be between 30% and 70% of the rated load.

dimmer gets hot or has a burning smell.
The dimmer is overloaded, turn off and recalculate the load.
The dimmer is under loaded.

There are electronic transers that are not suitable for dimming.
