1. Remove the 2 Phillips screws from the lamp socket assembly. Pull the lamp and socket out of the head.
2. Remove the old lamp, if any, from the socket.
3. Holding the new lamp by its ceramic base (do not touch the glass), align the small pin with the
small hole and insert the lamp squarely into the socket. Make sure that the 4 small projections on the
base contact the face of the socket.
4. Clean the glass bulb with the cloth supplied with the lamp, particularly if your fingers touched the
glass. A clean, lint-free cloth wetted with alcohol may also be used.
5. Gently insert the assembly, making sure the lamp fits through the opening in the reflector. Replace
the 2 screws.
6. The reflector is pre-adjusted at the factory; however, precise alignment to compensate for variations
between lamps may improve performance. See "Optimizing reflector alignment" on page 15.

For protection from dangerous electric shock, the fixture must be grounded
(earthed). The AC mains supply shall be fitted with a fuse or circuit breaker and
1. Verify that the voltage and frequency settings match the local AC supply. The factory settings are printed on
a label under the base. Check Table 7 on page 20 to verify that these settings are correct for your local AC
voltage. Operating at the incorrect power setting can result in poor light output, greatly reduced lamp life,
overheating and damage to the fixture. Refer to "Changing voltage and frequency settings" on page 20 if the
settings need to be adjusted.
2. Install a grounding-type cord cap that fits your supply on the power cable. Following the manufac-
turer's instructions, connect the yellow/green wire to the ground (earth) pin, the blue wire to the neu-
tral pin, and the brown wire to the live pin. The table shows some possible pin identification schemes;
if the pins are not clearly identified, or if you have any doubts about proper installation, consult a
qualified electrician.

3. Verify that the supply cable is undamaged and rated for the current requirements of all connected
devices.
4. Plug the prepared power cable into the 3-prong IEC inlet and a grounded AC power supply. Do not
connect the fixture to a dimmer system.
