9.1 General considerations
Notice on optical radiation from NJORD Projector when it becomes Risk Group 3.
• For RG3, no direct exposure to the beam shall be permitted.
For RG3, operators shall control access to the beam within the hazard distance or install the product at a
height that will prevent eye exposure within the hazard distance.
• This projector has five (5) built-in Class 4 laser clusters. Disassembly or modification is very dangerous
and should never be attempted.
• Any operation or adjustment not specifically instructed by the user ’ s guide creates the risk of hazardous
laser radiation exposure.
• Do not open or disassemble the projector as this may cause damage by the exposure of laser radiation.
FOR PROFESSIONAL USE ONLY means installation can only be carried out by Barco AUTHORIZED
PERSONNEL familiar with potential hazards associated with high intensity light beams.
9.2 Safety training to be provided by the installer
Refer to document 601 – 0462 “ Declaration of user safety training ” for training tick off and signing.
WARNING: The installer is responsible that the user is instructed. The user will sign a document to
confirm that the instructions have been received and understood.
Restricted access location
To protect untrained persons and children, the projector must be installed in a restricted access location .
The definition of a restricted access location is a location for equipment where both of the following
paragraphs apply:
• Access can only be gained by skilled persons (installer or service personnel) or persons who have been
instructed and trained by a skilled person. The persons must have been instructed about the reasons for
the restriction applied to the location and about the precautions that shall be taken.
• Access is only possible 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 in
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 ” , page 63.
Users definition
The Njord is intended for persons who have been instructed and trained by a skilled person (installer or
service personnel) to identify energy sources that may cause injury and to take precautions to avoid
unintentional contact with or exposure to those energy sources.
The skilled person must instruct the user about:
• High intensity light beam. The user must respect the exclusion zone, based on the light beam Hazard
Distance (HD).
• Dangerous energy sources inside the projector. The user is not allowed to remove any cover from the
projector.
• The installation, maintenance or service is for skilled persons only.
• The requirements for a restricted access location , an exclusion zone and a restriction zone .
Exclusion zone
The projector radiates heat on its external surfaces and from ventilation ducts during normal operation.
Exposing flammable or combustible materials into close proximity of this projector could result in the
