bent when uncoiling. Ensure that is never bent to less than the minimum bend radius. Never
pull on the optical connector to untangle the conduit.
Particular care should be taken with regard to possible damage to the optical connector when
uncoiling the bean delivery optic as there is a tendency for the coil to spring apart which may
cause the optical connector to collide with other objects. Do not drop the optical connector or
allow it to hit surfaces or other objects.
7 Installation
7.1 Safety and Compliance During Installation
CAUTION: This QUBE Fiber Laser is heavy and so precautions
must be taken when lifting and moving.
Failure to do so may cause serious injury
This QUBE Fiber Laser is heavy. To avoid the risk of personal injury or damage to the QUBE
Fiber Laser when lifting or moving, lift with two people and use a trolley or similar mechanical
assistance when moving over distance.
Before installation reference should be made to Section 3 regarding laser safety, electrical
safety, EMC and compliance. When installed, the QUBE Fiber laser and the additional
equipment required to operate it should not obstruct access to safety devices or impair their
operation.
It is recommended that installation is done in the sequence of the following sections, with
water connections made and checked before electrical connections are made.
7.2 Location and Environment
This QUBE Fiber Laser is designed for operation within the environment specified in Table 20.
Operating the QUBE Fiber Laser beyond the limits of the environmental specification may lead
to accelerated component ageing and performance degradation. As the QUBE Fiber Laser is
water-cooled care must be taken to ensure that it is always operated above the dew point so
that internal condensation is avoided. Refer to Figure 67 for a chart showing the relationship
between relative humidity, ambient air temperature and cooling water temperature for non-
condensing operation. To reduce the risk of internal condensation should the cooling water
temperature fall below the dew point, the QUBE Fibre Laser automatically regulates the flow
of cooling water to keep the internal surfaces above the dew point
This QUBE Fiber Laser should not be installed in a corrosive atmosphere.
This QUBE fiber laser should not be exposed to high levels of optical radiation, for instance
radiation from materials processing.
This QUBE Fiber Laser is sealed against dust and water ingress to IP52 to BS EN
60529:1992+A2:2013 with the exception of the electrical connectors which are rated IP50.
