5. k simply follow the directions below Earth Grounding Considerations When using the 244 LaserMount with Arroyo Instruments LaserSource or TECSource and cables the 244 will be earth grounded through the cables and instrument However if you are using another vendor s cables or instruments verify the earth ground path and that proper grounding techniques are used The mount has a banana jack that provides a case connection which can be used for a wrist strap if the case is earth grounded or to tie the case to earth ground through something other than the laser driver or temperature controller Internal Cooling Fan The 244 LaserMount has an integrated cooling fan for the heat sink which allows operation at high heat loads If you are using an Arroyo Instruments 5300 Series TECSource temperature controller the fan supply is built directly into the TECSource You will need to enable the fan supply the TECSource menu see the TECSource manual for additional details If you are using a third party temperature controller then you will need to provide a 12V DC power supply The connection into the mount is a standard 2 1mm round plug with the center pin positive and must be capable of supplying at least 150mA The fan 12VDC and ground connections are completely isolated from the rest of the fixture For quieter fan operation the voltage can be reduced as low as 8VDC although there will be a slight reduction in thermal capabil
