1. Disconnect the fixture from power and allow to cool for at least 20 minutes.
2. Remove the 2 Phillips screws in the access cover directly behind the power and data connectors (see
Figure 2). Lift off the cover.
3. Locate the selection switches.
4. Move the voltage switch to the setting that most closely matches the local AC voltage. If your voltage
falls between 2 settings, select the higher voltage. For example, if your AC voltage is 220 V, use the 230
V setting instead of 210 V.
5. Move the frequency switch to the setting that matches the local AC frequency: 50 or 60 Hz.
6. Replace the cover.
The main fuse is suitable for all AC power voltages and frequencies accepted by the fixture and does not
need to be replaced when the fixture's settings are changed.

The power cable must be fitted with a grounding-type cord cap (mains plug) that fits your power distribution
system. Consult an electrician if you have any doubts about proper installation.
Following the cord cap manufacturer's instructions, connect the yellow and green wire to ground (earth), the
brown wire to live, and the blue wire to neutral. The table below shows some pin identification schemes.
