Mounting
2-12. Mount the laser head by means of the three slotted mounting tabs that extend outward from the
bottom edges of the unit (refer to Figure 2-1 for exact locations and dimensions). The mounting tabs may be
secured to the work surface in any fashion that will not transmit stresses to the main enclosure and,
consequently, to the laser tube or printed-circuit assemblies. If necessary, the tabs can be removed and the
unit can be mounted on a flat surface with 8-32 machine screws; use the same tapped holes that are used to
secure the tabs.
Do not clamp the unit at any point other than the mounting tabs.
To do s o can damage the unit.

Power and Signal Connections
2-14. The laser head rear panel contains three multi-pin connectors that are used for power and signal
connection of the laser head to the remaining components of a laser transducer system. (Refer to Figure 2-2
for an interconnection diagram of a typical system.)Table2-1 listsall power and signal lines that are available
at the three rear-panel connectors. The laser transducer system manual gives additional system wiring
information.
