Safety Considerations
The Model HP 8I53A is a Class 1 instrument (that is, an instrument
with an exposed metal chassis directly connected to earth via the
power supply cable). The symbol used to show a protective earth
terminal in the instrument is ~ .
Before operation, you should review the instrument and manual,
including the red safety page, for safety markings and instructions.
You must follow these to ensure safe operation and to maintain the
instrument in safe condition.
Some HP 8I53A circuits are powered whenever the instrument is
connected to the AC power source. To disconnect from the line
power , disconnect the power cord either at the rear power-inlet or at
the AC line-power source (receptacle). One of these must always be
accessible. If the instrument is in a cabinet, it must be disconnected
from the line power by the system's line-power switch.
Initial Inspection
Inspect the shipping container for damage. If there is damage to
the container or cushioning, you should keep them until you have
checked the contents of the shipment for completeness and verified
the instrument both mechanically and electricaliy.
The Performance Tests give procedures for checking the operation of
the instrument. If the contents are incomplete, mechanical damage or
defect is apparent , or if an instrument does not pass the operator's
checks, notify the nearest Hewlett-Packard office.
Warning To avoid hazardous electrical shock, do not perform electrical tests
when there are signs of shipping damage to any portion of the outer
enclosure (covers, panels, etc.),
Line Power Requirements
The HP 8I53A can operate from any single-phase AC power source
that supplies between 100V and 240V at a frequency in the range
from 40 to 60Hz. The maximum power consumption is 55VA with ali
options instalied.
The fuse used by this instrument is TIA / 250V (slow) (HP Part No.
2110-0007). This fuse is located on the power supply board.

Line Power Cable
Warning
iv
In accordance with international safety standards, this instrument
has a three-wire power cable. When connected to an appropriate AC
power receptacle, this cable earths the instrument cabinet. The type
of power cable shipped with each instrument depends on the country
of destination. Refer to Figure Q-l for the part numbers of the power
cables available.
To avoid the possibility of injury or death, you must observe the
following precautions before switching on the instrument.
• If this instrument is to be energized via an autotransformer for
voltage reduction, ensure that the Common terminai connects to the
earthed pole of the power source.
• Insert the power cable plug only into a socket outlet provided with a
protective earth contact. Do not negate this protective action by the
using an extension cord without a protective conductor.
• Before switching on the instrument, the protective earth terminai of
the instrument must be connected to a protective conductor. You
can do this by using the power cord supplied with the instrument.
• It is prohibited to interrupt the protective earth connection
intentionally.

The following work should be carried out by a qualified electrician,
and all local electrical codes must be strictly observed. If the plug
on the cable does not fit the power outlet, or if the cable is to be
attached to a terminal block, cut the cable at the plug end and
rewire it.
The color coding used in the cable depends on the cable supplied.
If you are connecting a new plug, it should meet the local safety
requirements and include the following features:
• Adequate load-carrying capacity (see table of specifications).
• Ground connection.
• Cable clamp.
Operating Environment The following summarizes the HP 8153A operating environment
ranges. In order for the HP 8153A to meet specifications, the
operating environment must be within these limits.
Warning The HP 8153A is not designed for outdoor use. To prevent potential
fire or shock hazard, do not expose the HP 8153A to rain or other
excessive moisture.
Temperature
The HP 8153A may be operated in temperatures from O°C to 55°C.

vi
The HP 8153A may be operated in environments with humidity up
to 95% (O°C to +40°C). The HP 8153A should be protected from
temperatures or temperature changes that cause condensation within
the instrument.
The HP 8153A has a cooling fan mounted internally. Mount or
position the instrument so that air can circulate through it freely.
When operating the HP 8153A, choose a location that provides at
least 75mm (3inches) of clearance at the rear, and at least 25mm
(linch) of clearance at each side. Failure to provide adequate air
clearance may result in excessive internal temperature, reducing
instrument reliability.
A maximum of 15V can be applied as an external voltage to any of
the BNC connectors.
The instrument can be stored or shipped at temperatures between
-40°C and +70°C. The instrument should be protected from
temperature extremes that may cause condensation within it.
