VENTILATION REQUIREMENTS: When installing the product in a cabinet,
the convection into and out of the product must not be restricted. The
ambient temperature (outside the cabinet) must be less than the
maximum operating temperature of the product by 4° C for every 100
watts dissipated in the cabinet. If the total power dissipated in the
cabinet is greater than 800 watts, then forced convection must be used.
Install the instrument so that the detachable power cord is readily
identifiable and is easily reached by the operator. The detachable power
cord is the instrument disconnecting device. It disconnects the mains
circuit from the mains supply before other parts of the instrument. The
front panel switch is only a standby switch and is not a LINE switch.
Alternatively, an externally installed switch or circuit breaker (which is
readily identifiable and is easily reached by the operator) may be used as
a disconnecting device.
There is no output laser aperture
The Keysight 86120D and 86122C do not have an output laser aperture.
However, light less than 1 nW escapes out of the front- panel OPTICAL
INPUT connector. Operator maintenance or precautions are not necessary
to maintain safety. No controls, adjustments, or performance of
procedures result in hazardous radiation exposure.
