Safety and Regulatory Information
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
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.
This instrument has autoranging line voltage input. Be sure the supply voltage is
within the specified range.
This product is designed for use in Installation Category II and Pollution
Degree 2 per IEC standards.
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.
Servicing
These servicing instructions are for use by qualified personnel only. To avoid
electrical shock, do not perform any servicing unless you are qualified to do so.
No operator serviceable parts inside. Refer servicing to qualified personnel. To
prevent electrical shock, do not remove covers.
The opening of covers or removal of parts may expose dangerous voltages.
Disconnect the instrument from all voltage sources while it is being opened.
