General Safety Considerations
WARNING
Before this instrument is switched on , make sure it has been properly
grounded through the protective conductor of the ac power cable to a
socket outlet provided with protective earth contact.
Any interruption of the protective (grounding) conductor, inside or
outside the instrument, or disconnection of the protective earth terminal
can result in personal injury.
WARNING
There are many points in the instrument which can, if contacted, cause
personal injury
.Be
extremely careful.
Any adjustments or service procedures that require operation of the
instrument with protective covers removed should be performed only by
trained service personnel.
WARNING
If this instrument is not used as specied, the protection provided by the
equipment could be impaired. This instrument must be used in anormal
condition (in which all means for protection are intact) only
.
WARNING
F
or continued protection against re hazard, replace line fuse only with
same type and ratings (type nA/nV). The use of other fuses or materials is
prohibited.
WARNING
The power cord is connected to internal capacitors that may remain live
for 5 seconds after disconnecting the plug from its power supply
.
CAUTION
Before this instrument is switched on, make sure its primary power circuitry
has been adapted to the voltage of the ac power source.
Failure to set the ac power input to the correct voltage could cause damage to
the instrument when the ac power cable is plugged in.
CAUTION
This is aSafety Class 1Product (provided with aprotective 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 instrument is likely to make
the instrument dangerous
. Intentional interruption is prohibited.
iv

CAUTION
Always use the three-prong ac power cord supplied with this instrument.
Failure to ensure adequate earth grounding by not using this cord may cause
instrument damage.
CAUTION
This instrument is designed for use in INSTALLATION CATEGORY II and
POLLUTION DEGREE 2 per IEC 1010 and 664 respectively.
CAUTION
Ventilation requirements: When installing the instrument in a cabinet,
the convection into and out of the instrument must not be restricted. The
ambient temperature (outside the cabinet) must be less than the maximum
operating temperature of the instrument by 4

C for every 100 watts
dissipated in the cabinet. If the total power dissipated in the cabinet is
greater than 800 watts
,thenforced convection must be used.
CAUTION
The input circuits can be damaged by electrostatic discharge (ESD). Repair
of damage due to misuse is
not
covered under warranty
.Therefore
,avoid
applying static discharges to the front-panel input connectors
.Before
connecting any coaxial cable to the connectors
,momentarily short the center
and outer conductors of the cable together
.A
void touching the front-panel
input connectors without rst touching the frame of the instrument. Be sure
the instrument is properly earth-grounded to prevent buildup of static charge
.
The electrical ports of plug-in modules
,used with the HP 83480A and
HP 54750A,arevery sensitive to electrostatic discharge
.
NOTE
This instrument has been designed and tested in accordance with IEC Publication 1010.1, and has been
supplied in a safe condition. The instruction documentation contains information and warnings which
must be followed by the user to ensure safe operation and to maintain the instrument in a safe
condition.

NOTE
Clean the cabinet using a damp cloth only.
