General
Do not use this product in any manner not specified by the
manufacturer. The protective features of this product may be
impaired if it is used in a manner not specified in the operation
instructions.
WARNING Only fuses with the required rated current, voltage, and specified type
(normal blow, time delay, etc.) should be used. Do not use repaired fuses
or short-circuited fuseholders. To do so could cause a shock or fire
hazard.
This apparatus has been designed and tested in accordance with
IEC Publication 348, Safety Requirements for Measuring Apparatus,
and has been supplied in a safe condition. This is a Safety Class I
instrument (provided with terminal for protective earthing). Before
applying power, verify that the correct safety precautions are taken
as described in the following warnings. In addition, note the
external markings on the instrument as described in
Table 1 on
page 8.
WARNING If the instrument is damaged, or if it fails to operate according to the
characteristics in this manual, remove the power cord and contact
Agilent Technologies.
WARNING Before turning on the instrument, you must connect the protective earth
terminal of the instrument to the protective conductor of the (mains)
power cord. The mains plug shall only be inserted in a socket outlet
provided with a protective earth contact. You must not negate the
protective action by using an extension cord (power cable) without a
protective conductor (grounding). Grounding one conductor of a
two-conductor outlet is not sufficient protection.
WARNING If you energize this instrument by an auto transformer (for voltage
reduction or mains isolation), the common terminal must be connected
to the earth terminal of the power source.
WARNING Whenever it is likely that the ground protection is impaired, you must
make the instrument inoperative and secure it against any unintended
operation.
