3.3 Hazards
3.3.1 Laser Hazards
All Warnings, including those in the Safety Notes and those in other sections of these
Instructions for Use, must be heeded.
Laser emissions from the housing of the Laser and the conduit of the beam delivery optic are
less than the AEL for Class 1 of IEC/EN 60825-1 with a single fault.
WARNING: Care must be taken especially when controlling this
Laser remotely across a network.
Failure to do so could result in another User being exposed to
hazardous levels of radiation.
It is the responsibility of the Laser Integrator to ensure that when
controlled remotely no hazardous levels of radiation are emitted
when unsafe to do so.
3.3.2 Electrical Hazard
CAUTION: This Laser is designed to BS EN 60204-
1:2006+A1:2009 and must be grounded for safety and to comply
with regional electrical codes.
Failure to do so may result in electric shock and incorrect operation
of the Laser.
This Laser is not provided with any electrical supply cable (cord, flex or lead).
Only qualified technical personnel who are familiar with the equipment should open the cabinet
doors. No electrical hazard exists if the system is operated normally.
3.3.3 Materials Processing Hazards
Materials processing can generate vapour, fumes, solid particulates and other air contaminants
that may irritate, be toxic, or even fatal. It is the responsibility of the user to ensure that all
relevant safety precautions are followed and that any legal requirements are adhered to in
accordance with local legislation. It is advised that Material Safety Data Sheets (MSDS) for any
material to be processed are evaluated and that adequate measures for fume extraction and
venting are considered. Interaction of the beam with certain materials can cause potentially
harmful levels of visible and invisible radiation to be emitted. Appropriate protective measures
must be taken.

CAUTION: It is essential that any debris associated with laser
processing is removed and cleaned away on a regular basis.
Failure to do so may result in fire.
3.3.4 Other Hazards
While most of the hazard comes from laser radiation, there are certain non-beam hazards that
are often associated with use of laser systems. The Laser requires AC power and is water-
cooled. Electricity and water, individually or in combination, may create hazards.
Mechanical hazards may include moving parts in cutting, welding and material handling
systems.
High temperatures and fire hazards may also result from the operation of Class 4 lasers.
3.4 Compliance
Within the EU, the Laser is CE marked and is supplied with a Declaration of Conformity. The
standards which SPI Lasers declares that the Laser is in conformity with, and the directives
which SPI Lasers declares that the Laser complies with the requirements of are listed in the
Declaration of Conformity.
Within the USA, the Laser is shipped with an appropriately completed FDA 2877 form.
It is the responsibility of the Laser Integratorto ensure that the integrated laser system conforms
with the appropriate standards and complies with the appropriate directives. Nonetheless, many
of the electronic and labelling requirements have been incorporated into the Laser to facilitate
compliance.
3.4.1 Europe: WEEE Directive

laser processing applications. It gives laser integrators the capability to manufacture industrial
laser machines with maximum output power levels from 3kW to 8kW. QUBE Fiber Lasers can
be operated in continuous wave (CW) or modulated (CWM) modes for applications enabled by
fiber lasers and applications traditionally served by lamp pumped and diode pumped solid-state
lasers. A flexible control architecture has been implemented using a combination of analogue,
digital and logic user interfaces.
The optical power is generated by two or more PRISM Fiber Laser (FL) Modules which use SPI
Lasers’ proprietary
1
GTWave®active fiber technology and reliable pump diodes to produce a
high power, high brightness output. The output from the PRISM Fiber Laser Modules is coupled
together in a PRISM High Power Combiner (HPC) Module and is guided to the Laser Integrator’s
optics by a multimode (MM) delivery fiber supplied with an industry standard PIPA-Q connector.
A ruggedised conduit including SPI Lasers’ Fiber Continuity Monitoring System (FCMS) protects
the delivery fiber.
The PRISM FL Modules together with the pump diode PSU and power distribution and control
systems are enclosed in a cabinet. There are two sizes of cabinet, of different heights, capable
of holding up to two and up to four PRISM FL Modules respectively.
