1.2 Safety Precautions
CAUTION
The LED's Heads provide optical output power classified as RISK GROUP 3 as per IEC/EN 62471-2.
The user related risk of this system is dependant on the final installation and use of this product as
detailed within this manual.
Always follow the installation guidelines as detailed in the LX500 User Guide, 035-00628R. Use of
this system in any manner not specified by Excelitas Canada Inc. may expose the user to potentially
hazardous optical radiation and UV.
RISK GROUP 3
WARNING: UV emitted from this product. Avoid eye andskin exposure to unshielded product.
CAUTION: Possibly hazardous optical radiation emitted from this product. Do not stare into
operating lamp.
WARNING
Do not stare directly at the LED aperture(s). This may be harmful, resulting in eye injury. Always use
protective eyewear with this device. Additionally, protect any exposed skin with appropriate clothing
or shielding as required.
Warning UV protective eyewear must meet the following recommended optical specifications:
• Spectral range; 350-440nm
•Optical Density ≥6
WARNING
To prevent accidental exposure to hazardous optical/ UV radiation, always ensure that the LED
heads are properly secured in a mounting fixture as described in the LX500 User Guide 035-00628R.
Hand held use of the LED heads is not recommended and may expose the user to dangerous optical
radiation. Additionally, to prevent unintentional exposure, use of the on/off key switch on the LX500 is
recommended. It is recommended to unplug the power from the LX500.
Caution, Hot Surface
Due to elevated operating temperatures; avoid contact of the LED head(s) when energized The LED
heads are designed to be mounted in a suitable fixture prior to use. User clamp type heat sink
assemblies are available for each LED head to provide user safety and optimum thermal
management.
Prior to handling and cleaning of the UV LED head(s), allow a cool down for a period of approximately
5 minutes after system power has been removed.
Cleaning
Prior to attempting to clean the lens assembly, always disconnect the external power supply cord
from the controller chassis. Use only a cloth slightly dampened with an appropriate optical cleaning
solution to clean the lens cover assembly of the UV LED head. Applying a cleaning solution to the hot
lens assembly may result in contamination or undesirable residue, resulting in decreased optical
performance.
The UV LED head’s operation can be affected if handled incorrectly. Never touch the protective lens
cover assembly of the UV LED head. The presence of skin oils may result in a decrease in system
performance.
Always ensure the system controller power is turned off, prior to disconnecting or re-connecting any
of the UV LED heads.
