AC power

You may need to fit the power cable with a power plug that is suitable for your AC power outlets.
If so, install a grounding-type (earthed) plug that is rated 10 A minimum. Follow the plug
manufacturer’s instructions. Table 2 shows some possible pin identification schemes. If pins are
not clearly identified, or if you have any doubts about proper installation, consult a qualified
electrician.
To connect to power:
1. Shut down power at source and ensure that it cannot be reapplied, even accidentally, by
removing a distribution circuit fuse for example.
2. Connect the conductors in the Alien LED Downlight driver unit power cable to the distribution
circuit as follows:
- Connect the yellow/green wire to ground (earth)
- Connect the blue wire to neutral
- Connect the brown wire
to live.
3. Check that all installation work is completed and carry out appropriate tests and safety checks
before applying power.
Power source quality
The Alien LED Downlight system includes combined power and data cables. The system is
robust and can withstand normal mains power disturbances, but more serious interference on the
mains power circuit can cause individual downlights in multiple installations to lose step
temporarily, typically for a fraction of a second, until they recover and normal operation is
resumed. If momentary loss of step occurs, check the quality of your incoming mains power and
ensure that Alien LED Downlight cables are separated from any other cables that may be
carrying large amounts of noisy power.
