Safety & Warnings
This product has been designed and tested in accordance with IEC Publication 61010-1, Safety Requirements for Electrical Equipment for Measurement, Control and Laboratory Use, and has been supplied in a safe condition. The instruction documentation contains information and warnings that must be followed by the user to ensure safe operation and to maintain the product in a safe condition.
WARNING: Light energy can radiate from the front panel OUTPUT connectors on Agilent 83492A and 83493A modules. The light emitted from these connectors is the slightly attenuated light that is input to the front-panel INPUT connector.
WARNING: If this instrument is not used as specified, the protection provided by the equipment could be impaired. This instrument must be used in a normal condition (in which all means for protection are intact) only.
WARNING: To prevent electrical shock, disconnect the Agilent 83491/2/3A from mains before cleaning. Use a dry cloth or one slightly dampened with water to clean the external case parts. Do not attempt to clean internally.
WARNING: This is a Safety Class 1 product (provided with a protective earthing ground incorporated in the power cord). The mains plug shall only be inserted in a socket outlet provided with a protective earth contact. Any interruption of the protective conductor inside or outside of the product is likely to make the product dangerous. Intentional interruption is prohibited.
WARNING: No operator serviceable parts inside. Refer servicing to qualified personnel. To prevent electrical shock, do not remove covers.
WARNING: For continued protection against fire hazard, replace line fuse only with same type and ratings, (type T 0.315A/250V for 100/120V operation and 0.16A/250V for 220/240V operation). The use of other fuses or materials is prohibited. Verify that the value of the line-voltage fuse is correct.
CAUTION: Before switching on this instrument, make sure that the line voltage selector switch is set to the line voltage of the power supply and the correct fuse is installed. Assure the supply voltage is in the specified range.
CAUTION: This product is designed for use in Installation Category II and Pollution Degree 2 per IEC 1010 and 664 respectively.
CAUTION: VENTILATION REQUIREMENTS: When installing the product in a cabinet, the convection into and out of the product must not be restricted.
