Alien LED Downlight user manual
Connecting heads
Whether you use DMX control or stand-alone operation, you need to connect heads so that
luminaires can draw power from transformers. See Figure 2 on page 10.
Warning! Ensure that the total current draw on both of the driver unit’s output sockets
added together does not exceed 5 A maximum.
Connect only Alien LED Downlight components to the Alien LED Downlight system, and
connect them only as shown in Figure 2 on page 10. Use only the cables supplied with the
system, and check that cables are in perfect condition before use.
Important! Before connecting two standard luminaires to a transformer, look carefully at
the RJ-45 T-connector used to branch the cable from the transformer. See Figure 2. The
RJ-45 sockets that must be used for input and output are clearly marked with arrows.
Observe these markings carefully, or you will damage the circuits in the T-connector.
Power cables that carry a strong current can affect the data signal in Alien LED Downlight
cables (see “Power source quality” on page 13). Route Alien LED Downlight system
cables as far as possible from potential sources of interference.
To connect heads:
1. Each transformer is hard-wired with a 1.5 m (4.9 ft.) power/data cable tail with an IEC male
connector. Connect the cable tail of the first transformer to the IEC female power/data output
socket of the first driver unit.
2. Continue linking transformers by connecting their cable tails to either a power/data output
socket on another transformer or a power/data output socket on a driver unit, up to a
maximum of 10 transformers in total per driver unit.
3. Each Alien LED Downlight luminaire is hard-wired
with a 1.5 meter (4.9 ft.) cable tail with an RJ-45
connector. Connect either:
a. two standard luminaires via the supplied 100
mm power patch cable and RJ-45 T-connector or
b. one high-power luminaire
to the RJ-45 output socket of each transformer.
See Figure 2. If you connect two standard luminaires
using a T-connector, use the connector with the
inward-pointing arrow for input from the transformer
and use the two outward-pointing arrows for output to
the luminaires.
