EXPOSURE TO THE LASER BEAM CAN RESULT IN BURNS TO THE SKIN AND
SEVERE EYE DAMAGE.Proper use and care of this system are essential to safe operation.
Use of controls,
adjustments, or performance of procedures other than those specified herein
may result in exposure to hazardous laser radiation.
WHEN USING THE OPTIONAL CLASS 4 PASS-THROUGH MODULE, PROPER
EYEWEAR MUST BE USED AT ALL TIMES WHEN THE BEAM INDICATOR IS
ILLUMINATED ON CLASS 4 CONTROL PANEL.
Eyewear must be properly certified for use
with and protection from all material processing laser wavelengths in use (10.6 µm, 9.3 µm,
and 1.06 µm, and at least an optical density 5+. If unsure of proper eyewear requirements
, do
not operate the laser system with Class 4 Pass-Through installed, and consult your certified
Laser Safety Officer (LSO) or a ULS Service Team member for more information.
SOME MATERIALS CAN PRODUCE TOXIC AND CORROSIVE FUMES DURING LASER
PROCESSING. Obtain the Material Safety Data Sheet (MSDS) fr om the manufacturer for
every material to be processed in the laser system
. T he MSDS discloses all hazards when
handling
or processing a particular mat e rial .

14
DISCONTINUE PROCESSING ANY MATERIAL THAT CAUSES CHEMICAL
BREAKDOWN
OF THE LASER SYSTEM. Damage t o the laser system such as rust, metal
etching, or
pitting , peeling paint, et c . from corrosive fumes is NOT covered under warrant y.
NEVER LEAVE THE LASER SYSTEM UNATTENDED WHILE IN OPERATION. AN
OPERATOR MUST BE PHYSICALLY PRESENT IN FRONT OF THE LASER SYSTEM AT
ALL TIMES TO SUPERVISE LASER PROCESSING. Exposure to the laser beam may cause
combustible materials to ignite, which may lead to fire. A PROPERLY MAINTAINED FIRE
EXTINGUISHER SHOULD ALSO BE KEPT ON HAND AT ALL TIMES.
THE OPTIONAL FIRE SUPPRESSION MODULE DOES NOT NEGATE THE NEED FOR
CONSTANT SUPERVISION OF ALL LASER CUTTING, MARKING AND ENGRAVING
PROCESSES. Fire Suppression is intended to reduce or eliminate damage to the laser
system due to sustained material combustion during laser processing resulting from
improper setup or absence of constant operator supervision. It is not certified for life safety,
nor is it intended as a replacement for certified fire suppression equipment required by
local or national laws and regulations.
REMOVE ALL MATERIAL, INCLUDING SCRAP MATERIAL, FROM THE MACHINE
AFTER EACH USE. Scrap material left in the laser system, including materials that collect in
the Multifunction Material Support Structure, can become a fire hazard. CAUTION WHEN
HANDLING MATERIAL IMMEDIATELY AFTER LASER PROCESSING, THE
MATERIAL MAY BE HOT.
DANGEROUS VOLTAGES ARE PRESENT WITHIN THE ELECTRONICS ENCLOSURES
OF THIS LASER SYSTEM.Access to these areas (marked with safety labels) is not
necessary during normal operation. If it becomes necessary to open one of these enclosures,
the laser system must first be disconnected from the power source.
NEVER REMOVE THE GROUND LEAD TO THE ELECTRICAL CORD AND PLUG THE
LASER SYSTEM INTO A NON-GROUNDED OUTLET. Without proper grounding, a laser
system is hazardous, can cause severe or fatal electrical shock, and may exhibit sporadic
or unpredictable behavior. ALWAYS PLUG A LASER SYSTEM INTO AN EARTHED OUTLET.
THE POWER SUPPLY CORD IS THE LASER SYSTEM’S MAIN DISCONNECT DEVICE.
THE EQUIPMENT SHOULD BE LOCATED NEAR AN EASILY ACCESSIBLE POWER
OUTLET.
To disconnect the equipment from the supply mains , the power cord should be
unplugged from the power outlet or main power inlet (appliance coupler) .
THIS LASER SYSTEM IS DESIGNED AS A CLASS I, GROUP A, PLUGGABLE DEVICE.
I t is also designed for connection to IT power systems . To satisfy European Standard
EN 610000-3-11 for Voltage Fluctuation and Flicker, the ULTRA X6000 laser system must be
connected to an AC supply with a low impedance (Zmax=0.049 OHMs) or less. End users
may consult with a power supply authority to ensure their AC supply line impedance meets
the requirements of EN 61000-3-11:2000 Annex B for low impedance connections.
DO NOT ATTEMPT TO MOVE OR LIFT THE LASER SYSTEM WITHOUT PROPER
EQUIPMENT. The ULTRA X6000 Platform should only be moved with the assistance of a
forklift or a palette jack. Before moving, ensure that the motion system and doors are
secured. Do not attempt to move by hand. Injury may occur
if improper lifting techniques
are used or if the system is dr opped . If unsure how to move the ULTRA platform, consult a
professional rigging company or the ULS Factory Support Team at: [e-mail].

15
Laser Safety
The ULTRA X6000 Platform is designed to support both sealed carbon dioxide (CO2) laser sources,
which produce intense invisible infrared laser radiation at 10.6 µm and 9.3 µm wavelengths, and fiber
laser sources that produce intense invisible infrared laser radiation at 1.06 µm wavelength. For optimal
safety, all ULS lasers are enclosed within a Class 1 laser safety enclosure designed to completely
contain CO2or fiber laser energy.
This enclosure does not permit human access to laser radiation in
excess of the accessible emission limits of
Class 1 for the applicable wavelength and emission
duration.
USE OF CONTROLS OR ADJUSTMENTS, OR PERFORMANCE OF
PROCEDURES OTHER THAN THOSE SPECIFIED HEREIN MAY RESULT IN
EXPOSURE TO HAZARDOUS LEVELS OF INVISIBLE LASER RADIATION.
DO NOT OPERATE THE LASER SYSTEM WITH A DAMAGED VIEWING
WINDOW, WITH ANY DOORS OPEN OR REMOVED (EXCEPT WHEN
PROPERLY OPERATING AS CLASS 4), OR WITH ANY SAFETY
INTERLOCKS MODIFIED OR DEFEATED.
•Laminated safety glass is employed in the viewing window to block 10.6 µm and 9.3 µm laser
radiation from CO2lasers. This viewing window will block transmission of CO2laser radiation
enabling safe observation of laser material processing. For laser systems configured with fiber
lasers, a special blue tinted material is used in conjunction with the laminated safety glass to
block both 10.6 and 9.3 µm CO2and 1.06 µm fiber laser energy. DO NOT OPERATE THE
LASER SYSTEM IF THE VIEWING WINDOW IS DAMAGED, OR WITH ANY OF THE
DOORS REMOVED, OR IF ANY SAFETY INTERLOCKS ARE DEFEATED.
•The intense light that appears during laser material processing is the product of material
combustion or vaporization. DO NOT STARE DIRECTLY AT THIS INTENSE LIGHT FOR
LONG TIME PERIODS OR VIEW INDIRECTLY WITH OPTICAL INSTRUMENTS SUCH
AS BINOCULARS OR MICROSCOPES.
•This device also contains a visible, Class 2 red laser pointer to aid in material positioning.
DO NOT LOOK DIRECTLY INTO THE INTENSE LIGHT OF THE RED ALIGNMENT
POINTER FOR LONG TIME PERIODS OR USE A REFLECTIVE SURFACE TO
REDIRECT OR VIEW THE RED LASER LIGHT. NEVER ATTEMPT TO VIEW THE RED
LASER LIGHT USING OPTICAL INSTRUMENTS SUCH AS BINOCULARS OR
MICROSCOPES.
•The access door(s) are safety-interlocked, which will prevent the material processing laser beam
(CO2and fiber) from firing when an access door is opened. THE RED LASER POINTER IS
NOT SAFETY INTERLOCKED AND CAN BE ACTIVATED AUTOMATICALLY WITH THE
DOORS OPEN OR CLOSED.
•DO NOT OPERATE THE LASER SYSTEM IF ANY OF THE BUILT-IN SAFETY
FEATURES HAVE BEEN MODIFIED, DISABLED, OR REMOVED.
This may lead to
accidental exposure to invisible CO2or fiber laser radiation, which can result in severe
ey e
damage and/or burns to the skin.
•ALWAYS USE CAUTION WHEN OPERATING A LASER SYSTEM.

16
ULS Laser Sources
For safety reasons, ULS laser sources are not field-serviceable and are not to be disassembled by the
user. All Universal Laser Systems laser sources bear tamper-evident devices to prevent disassembly.
Damage to the tamper-evident devices may void the laser source warranty. If a ULS laser source
needs service, contact the ULS Support Team at: [email protected], or call: [phone], the
Austria Office at: [phone], or the Japan office at: [phone].
Laser System Owner Responsibility and Safety Measures
The “Owner” of a laser system is the individual or entity who maintains ultimate control over and
rights to the product and is fundamentally responsible to ensure the safe use of lasers owned by,
and/or operated in facilities under their control. This includes the establishment and maintenance of
an adequate program for the control of laser hazards.
Many of the mandatory safety measures are outlined in ANSI Standard Z136.1 American National
Standard for the Safe Use of Lasers or in similar standards in most foreign countries, such as the
European Standard EN 60825-1. State and local authorities may require other safety measures, for
example, Regulation BGV B2 for Safe Laser Usage put forth by the German Employer’s Liability
Insurance Association. It is the responsibility of the Owner to understand and adhere to these laws.
Laser Safety When Using Class 4 Pass-Through
The ULTRA X6000 laser system is equipped with interlocked access panels on either side of the unit. An
Optional Class 4 Pass-Through Module is available to enable the user to operate the laser system with
the side access panels open by bypassing their safety interlocks. With this optional device in place, the
protective system housing will not fully contain the infrared laser radiation produced by the laser
source(s), creating the potential for exposure to laser energy. Use of this optional device redefines the
safety classification of the ULTRA X6000 laser system from Class 1, considered safe for use under all
conditions of normal use, to Class 4, considered potentially hazardous.
EXPOSURE TO THE LASER MATERIAL PROCESSING BEAM CAN RESULT IN
BURNS TO THE SKIN AND CAN CAUSE SEVERE EYE DAMAGE. Proper use and
care of this system are essential for safe operation. Use of controls or adjustments or
performance of procedures other than those specified herein may result in exposure
to hazardous laser radiation
WHEN USING OPTIONAL CLASS 4 PASS-THROUGH, PROPER EYEWEAR
MUST BE USED AT ALL TIMES WHEN THE BEAM INDICATOR IS
ILLUMINATED ON THE CLASS 4 CONTROL PANEL. Eyewear must be properly
certified for protection from all material processing laser wavelengths in use (10.6
µm, 9.3 µm, and 1.06 µm) and must be at least optical density 5+. If unsure of
proper eyewear requirements, do not operate the laser system with Class 4 Pass-
Through installed and consult your certified LSO or contact ULS Support Team.
When operating in Class 4 mode, with the side access door(s) open, the system housing can no longer fully
contain flames or by-products from potential ignition of the materials being processed. Additional safety
precautions may be necessary. It should also be noted that reflected infrared laser radiation that escapes

17
the housing of a laser system operating in Class 4 mode can cause ignition of nearby flammable materials.
When operating in Class 4 mode, the environment around the laser system should be carefully organized
to ensure that there are no flammable materials in its immediate vicinity.
Mandatory safety measures set by national and international laws and standards exist that must be
complied with when operating a Class 4 laser system. Certain safety measures are provided by the
manufacturer and incorporated into the optional Class 4 Pass-Through module while other operational
safety measures are the responsibility of the ULTRA X6000 laser system Owner.
MANUFACTURER PROVIDED CLASS 4 SAFETY MEASURES
• Remote Interlock Connection – A means of remotely connecting to the interlock circuit of the
laser system enabling the connection of remote switches for deactivating the laser source. This
feature can be used to connect an interlock switch to the doors of the designated room in which
the laser system will be operated so that the laser source is automatically deactivated when the
side access panels are opened.
• Key Control – A removable key that prevents unauthorized operation of the laser system.
• Laser Radiation Emission Warning Device – A visible warning light that indicates when the
laser system is capable of emitting laser radiation.
• Attenuator – A mechanical device to block emission of laser radiation. This device takes the form
of a mechanical shutter opened and closed by the key control.
• Class 4 Warning Label – A Class 4 warning label to indicate the laser system is classified as Class 4.
OWNER PROVIDED CLASS 4 SAFETY MEASURES
THESE SAFETY MEASURES ARE THE RESPONSIBILITY OF THE OWNER AND ARE
MANDATORY FOR OPERATION OF CLASS 4 LASER SYSTEMS UNDER FEDERAL AND STATE LAW
IN THE UNITED STATES AS WELL AS UNDER THE LAWS OF MOST FOREIGN COUNTRIES.
A brief synopsis of the most common safety requirements addressed to Owners of Class 4 laser
systems is outlined below:
• In any facility in which a Class 4 laser system is operated, the owner must designate a Laser Safety
Officer (LSO) who will assume the authority and responsibility to monitor and enforce the control of
laser hazards. The LSO should be trained in laser safety and be aware of all safety measures set by
law. There are many avenues available to acquire this training. Recognized sources of this training
are the Laser Institute of America (www.laserinstitute.org), the Employer’s Insurance Liability
Associations in European countries, or laser safety associations within the Owner’s country/territory.
• The LSO will be responsible for creation of a controlled area in which the Class 4 laser system will be
operated. A controlled area is designed to fully contain laser radiation that can potentially escape
from a Class 4 laser system, with measures in place to prevent unauthorized personnel from
entering the area, including lighted warning signs and interlocks on all entryways.
• The LSO will be responsible for designating and training all personnel authorized to operate,
maintain, or service a Class 4 laser system. It will also be the responsibility of the LSO to take
measures to inform and to restrict all unauthorized personnel from access to a Class 4 laser system.
• The LSO will be responsible to identify and provide all authorized personnel any protective
equipment such as specially designed eyewear and clothing needed when operating, maintaining, or

18
servicing a Class 4 laser system.
• The LSO will ensure that no juveniles operate the laser.
• The LSO will regularly audit all safety measures including: regular retraining of authorized
personnel, serialization and regular inspection and replacement of all special eyewear and clothing,
and monitoring of all safety measures surrounding the controlled area in which a
Class 4 laser system is operated. The LSO may be required to maintain records as necessary
to prove compliance.
• The LSO will be responsible for regular medical surveillance of all authorized personnel
operating a Class 4 laser system. For example, this may include but is not limited to, mandatory
annual eye exams.
• Class 4 lasers systems must not be used at trade shows or exhibitions.
The above list is not to be considered all-inclusive. Other mandatory safety measures may be applicable
and will vary from state-to-state and country-to-country. IT IS THE RESPONSIBILITY OF THE
OWNER OF A CLASS 4 LASER SYSTEM TO IDENTIFY AND COMPLY WITH ALL PERTINENT
REGULATIONS.
In some states, for example, anyone wishing to operate a Class 4 laser system must register with the state
radiation regulatory agency, pay annual fees, and submit to annual inspections. There may be penalties
involved for non-compliance. The United States Occupational Safety and Health Administration (OSHA)
has also adopted rules for safe use of lasers in the workplace. The LSO must comply with all rules and
regulations set by law.
To reiterate, the safety measures relating to operation of a Class 4 laser system are mandatory under
Federal and State law in the United States as well as in most foreign countries. If an owner is unable or
unwilling to comply with all safety measures required for safe operation of a Class 4 laser system, the
optional Class 4 Pass-Through module must not be used.
Laser System Safety Labels
CDRH and CE regulations require that all laser manufacturers affix warning labels in specific
locations throughout the equipment. Do not remove these labels for any reason. If the label(s)
become damaged or have been removed for any reason, do not operate the laser system and
immediately contact the ULS Support Team for replacements at: [phone] or
[e-mail], the Austria Office at: [phone], or the Japan office at: +81 45 224-
2270.
