1.1 General considerations
General safety instructions
•
Before operating this equipment please read this manual thoroughly and retain it for future reference.
•
Installation and preliminary adjustments should be performed by qualified Barco personnel or by authorized Barco service dealers.
•
All warnings on the projector and in the documentation manuals should be adhered to.
•
All instructions for operating and use of this equipment must be followed precisely.
•
All local installation codes should be adhered to.
Notice on safety
This equipment is built in accordance with the requirements of the international safety standards IEC60950-1, EN60950-1, UL60950-1
and CAN/CSA C22.2 No.60950-1, which are the safety standards of information technology equipment including electrical business
equipment. These safety standards impose important requirements on the use of safety critical components, materials and insulation, in
order to protect the user or operator against risk of electric shock and energy hazard and having access to live parts. Safety standards
also impose limits to the internal and external temperature rises, radiation levels, mechanical stability and strength, enclosure construction
and protection against the risk of fire. Simulated single fault condition testing ensures the safety of the equipment to the user even when
the equipment's normal operation fails.
Notice on optical radiation
This projector embeds extremely high brightness (radiance) lasers; this laser light is processed through the projector's optical path. Native
laser light is not accessible by the end user in any use case. The light exiting the projection lens has been diffused within the optical path,
representing a larger source and lower radiance value than native laser light. Nevertheless the projected light represents a significant risk
for the human eye and skin when exposed directly within the beam. This risk is not specifically related to the characteristics of laser light
but solely to the high thermal induced energy of the light source; which is equivalent with lamp based systems.
Thermal retinal eye injury is possible when exposed within the Hazard Distance (HD). The HD is defined from the projection lens surface
towards the position of the projected beam where the irradiance equals the maximum permissible exposure as described in the chapter
“
Hazard Distance
”
.
WARNING:
No direct exposure to the beam within the hazard distance shall be permitted, RG3 (Risk Group 3) IEC EN
62471-5:2015
CAUTION:
Use of controls or adjustments or performance of procedures other than those specified herein may result in
hazardous radiation exposure.
Restricted access location
This product may only be installed in a restricted access location. The definition of a
“
restricted access location" is a location for
equipment where both of following applies:
•
Access can only be gained by SERVICE PERSONNEL or by OPERATORS who have been instructed about the reasons for the
restriction applied to the location and about the precautions that shall be taken.
•
Access is through the use of the tool or lock and key, or other means of security, and is controlled by the authority responsible for the
location.
Why a restricted access location: This is a RG3 product. Based on international requirements, no person is allowed to enter the projected
beam within the zone between the projection lens and the related Hazard Distance (HD). This shall be physically impossible by creating
sufficient separation height or by placing optional barriers. Within the restricted area operator training is considered sufficient. The
applicable separation heights are discussed in
“
High Brightness precautions: Hazard Distance (HD)
”
, page 7.
Users definition
Throughout this manual, the terms SERVICE PERSONNEL and TRAINED PROJECTIONIST refers to persons having appropriate
technical training and experience necessary to be knowledgeable of potential hazards to which they are exposed (including, but not
