If this product is to be energized via an external
WARNING
autotransformer for voltage reduction, make sure that its
common terminal is connected to a neutral (earthed pole) of the
power supply.
This instrument has autoranging line voltage input. Be sure the supply

voltage is within the specified range. (Refer to the Agilent Technologies
ESA Spectrum Analyzer Specifications Guide.)
Ventilation Requirements: When installing the product in a cabinet, the
CAUTION
convection into and out of the product must not be restricted. The
ambient temperature (outside the cabinet) must be less than the
maximum operating temperature of the product by 4 ˚C for every 100
watts dissipated in the cabinet. If the total power dissipated in the
cabinet is greater than 800 watts, then forced convection must be used.
Install the instrument so that the detachable power cord is readily

identifiable and is easily reached by the operator. The detachable power
cord is the instrument disconnecting device. It disconnects the mains
circuits from the mains supply before other parts of the instrument.
The front panel switch is only a standby switch and is not a LINE
switch. Alternatively, an externally installed switch or circuit breaker
(which is readily identifiable and is easily reached by the operator) may
be used as a disconnecting device.
