General Safety Considerations
Safety Earth Ground
The Mains wiring and connectors shall be compatible with the connector used in
the premise electrical system. Failure to ensure adequate earth grounding by not
using the correct components may cause product damage and serious injury.
Before Applying Power
3-4
If this product is not used as specified, the protection provided by the
equipment could be impaired. This product must be used in a normal
condition (in which all means for protection are intact) only.
Ventilation Requirements: When installing the instrument into a cabinet,
consideration shall be given to the convection flow into and out of the cabinet.
Consideration shall also be given to the individual instruments to avoid having
the heated discharge of one instrument become the cooling intake air for
another instrument. Another area of concern is verification that the maximum
ambient operating temperature of the instrument is not exceeded due to cabinet
installation. Keysight recommends forced air convection whenever an instrument
is installed in a cabinet and further recommends that the maximum operating
temperature of the cabinet be reduced 10 °C lower than the maximum operating
temperature of a single instrument. If there are any concerns or special
requirements, a Keysight Field Engineer should be consulted to assure instrument
temperature compliance and performance.
