redPOWER QUBE Cased Fiber Laser User Manual
The laser integrator should ensure that when installed the QUBE Fiber Laser is not likely to be
exposed to water, for instance from cooling water leaks.
At least 200mm clear space must be provided in front of and behind the QUBE Fiber Laser to
allow the BDO and electrical cables to be routed correctly.
The optical connector shall be mounted in a protective housing which prevents human access
to laser radiation (including errant radiation) in excess of the AEL for class 1, for example a
housing meeting the requirements of EN 60825-4. The protective housing shall withstand
exposures under reasonably foreseeable single fault conditions without human intervention.
7.3 Mounting
The total weights of QUBE Fiber Lasers of different rated powers are given in Table 32. The
front panels of the QUBE Fiber Laser have the conventional 4U dimensions enabling the
QUBE Fiber Laser to be fitted into a standard 19” rack cabinet.
Mounting options are given in FS-S00138, QUBE Cased Fiber Laser Installation Drawing
Ensure that the conduit carrying the delivery fiber is not kinked or snagged. Follow the
guidance given in Section 7.7 and allow sufficient space for correct routing of the conduit.
Failure to do so may result in permanent damage to the delivery fiber.
7.4 Cooling Water Connections
CAUTION: Ensure an approved overpressure safety device is
installed when connecting this QUBE Fiber Laser to an external
chiller or factory water supply. This should comply with ISO4126-1
(or equivalent) and be rated to protect the QUBE Fiber Laser
against a flow or differential water pressure in excess of that
specified in Table 25.
CAUTION: If cooling water is allowed to enter this QUBE Fiber
Laser enclosure, do not use the QUBE Fiber Laser and contact SPI
Lasers immediately.
Failure to do so may result in electrical shock and damage to the
QUBE Fiber Laser.
7.4.1 QUBE Fiber Laser
This QUBE Fiber Laser must be operated with a source of chilled water as specified in Section
17.3 It is provided with connectors for 12mm diameter hoses at the rear. Hoses should be
routed, observing the specified bend radius, so that any leaking cooling water or condensation
will be kept away from the QUBE Fiber Laser, and provision should be made to shut down the
QUBE Fiber Laser and shut off the cooling water flow when a leak is detected.
