Warning! For protection from dangerous electric shock, the fixture must
be grounded (earthed). The AC mains supply shall have
overload and ground-fault protection.
Important! Check voltage setting before applying power. Do not connect
the CX-2 to an electrical dimmer system: doing so can damage
the electronics.
Before use verify that the fixture’s power supply is correctly tapped for the local
AC voltage. The default voltage setting is printed on the serial number label near
the AC input. The “EU” version may be set to 230 or 245 V AC and the “US”
version may be set to 110 or 120 V AC. Use the setting that is closest to the local
supply voltage.
To change the voltage setting
1 Disconnect the fixture from AC power.
Release the 4 cover locks by turning
them a quarter-turn counterclockwise.
Lift the cover straight off.
2 Locate and disconnect plug PL124 on
the back edge of the printed circuit
board. It has red, yellow, and blue
wires.

V AC (US version), flip and move the
