Note:
Impact response spectrum: The curve of the maximum acceleration response generated by
the equipment under the stipulated impact motivation. Impact response spectrum II indicates
the duration of semi sinusoidal impact spectrum is 6ms.
Static load: The pressure from upside, that the equipment with package can endure when
the equipment is piled as stipulated.
10.8.3 Environment for Operation
1. Climate
Table 10-26 and Table 10-27 show the required climate environment in which the
OptiX OSN 7500 operates.
