Additional Installation Options
If the customer is choosing to secure the laser with three screws, additional locations for the mounting
screws are located at the rear corners of the base plate.
Possible Minor Modification (can easily be implemented)
The tapped holes at the base of the plate can be used if the customer wants to attach the laser to the adaptor
plate accessing it from the bottom through holes in the plate and screwing the bolts into the laser’s shipping
bracket plate.
It is possible to install an additional dowel pin at the back end of the laser and design a clamp that is screwed
on to the customers table. The clamp has the mating slot for the pin. There is a small gap (0.005” – 0.010”)
between the laser and the clamp in such a way that the clamp does not restrict the laser expansion but rather
limits the motion due to external shock. For this option, the optional service handle at the back of the laser
needs to be removed.
See “Outline Drawings” for complete laser head and power supply dimensions.
Mounting Requirements for the Power Supply
The
QPS
is in a rack mountable enclosure. The following installation procedure assumes the power supply
is installed into a standard 19-inch (48.3 cm) rackmount unit. Although such mounting is not required, this
is the most compact mounting configuration when two or more laser systems are combined.
The power supply can be mounted using appropriate rackmount rails or set on a rackmount tray. Ensure
that the rackmount unit is capable of supporting at least 16 kg (35 lb.). The front panel holes are only to be
used to secure the power supply in the rack and are
not
meant to support the power supply itself. Three 10-
32 screw holes are located along each side of the power supply to attach a rail or slide for rack mounting
the unit.
Provide at least 8 inches of room on the front and back of the QPS to allow cool and, preferably, clean air
to enter the front panel and to exhaust from the rear panel. Inadequate cooling causes the unit to overheat
and shut down. Damage caused by insufficient cooling is not covered by warranty.
If the power supply is mounted in a rack, make sure it is appropriately ventilated. Take measures to prevent
heated air exhausted from the back panels from returning to the cooling air intake on the front. Failure to
do so causes overheating, which shuts off the power supply and can even damage it. When using a closed
rack unit, provide positive filtered ventilation air that flows into the unit, then up past the mounted units
without obstruction, and exhausts from the back. Do not add full shelves between units, or heated exhaust
air is trapped and causes overheating.
Ensure that the electrical cables and interface cables are safely routed and are not under any strain. Avoid
conditions where these cables can be stepped on by personnel.
