redPOWER QUBE Cased Fiber Laser User Manual
attempting to install or integrate the QUBE Fiber Laser, please read this section to ensure all
requirements are understood.
17.1 Operating Conditions
This QUBE Fiber Laser is designed for indoor use and to be safe when operated within the
environmental conditions given in Table 20 and at the mains voltages given in Table 22.
Table 20 Environmental Operating Conditions
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.
The laser integrator should ensure that when installed the QUBE Fiber Laser is not exposed to
water.
Note that auxiliary equipment is required to operate the QUBE Fiber Laser. The environmental
operating conditions of the auxiliary equipment must be observed.
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
laser or other radiation from materials processing.
Water must not be allowed to condense on or in the QUBE Fiber Laser. Condensation can be
avoided by using cooling water at a temperature appropriate to the local humidity. Figure 67
can be used to determine if the atmosphere is condensing. The solid lines cover the permitted
cooling water temperatures for the QUBE Fiber Laser. For example, if the ambient air
temperature is 25°C and the relative humidity is 40% then there will be no condensation for
any cooling water temperature in the specified range as the condition is below the 18°C
cooling water curve. However, if the ambient air temperature is 30°C and the relative humidity
is 80% then the cooling water temperature should be above 26°C, and preferably 30°C, to
prevent condensation.
Alternatively, as the QUBE Fiber Laser includes a solenoid valve which regulates the flow of
cooling water to keep the internal surfaces above the dew point, a cooling water temperature
below the dew point may be used.
