WARNING : DO NOT MOUNT THE LUMINAIRE ON A NORMALLY FLAMMABLE SURFACE .
WARNING : UV RISK . The lamps usable on the luminaire emit an amount of UV RADIATION very dangerous
for human health if not properly shielded .
For this reason the luminaire MUST NEVER BE USED IN THE SITUATIONS WHEN DIRECT LIGHT
EMISSION FROM THE LAMP CAN OCCURR ( ex : Damaged or no front lens , no mirror , damaged internal
baffles , additional aperture on the housing )
4. INSTALLATION INSTRUCTIONS

A –The ballast is compatible with the luminaire .
B -The ballast is suitable for the electrical mains ( Voltage & Frequency ) .
C –The ballast is properly earthed ( use the ground continuity test present on De Sisti ballast ) and the
ballast main switch is in OFF position .
