Instrument Identification
Hewlett-Packard power supplies are identified by one serial
number. The letter "KR" designates Korea as the country of
manufacture, the first digit indicates the year (1 = 91, 2 = 92,
etc), the second two digits indicate the week, and the last five
digits of the serial number are a different sequential number
assigned to each power supply.
If the serial number on your instrument does not agree with
those on the title page of this manual, a yellow change sheet
may be included if a design change has affected the contents
of this manual.
INSTALLATION
Inspection
When you receive your power supply, inspect it for any obvi-
ous damage that may have occurred during shipment. If there
is damage, notify the carrier and the nearest HP Sales Office
immediately. Warranty information is printed on the inside
front cover of this manual. Save the shipping carton and
packing materials in case the supply has to be returned to
Hewlett-Packard in the future. If you return the supply for ser-
vice, attach a tag identifying the owner and model number.
Also include e brief description of the problem.
The "Turn-On Checkout Procedure" in this manual can be
used as an incoming inspection check to verify that the sup-
ply is operational. See the appendix for tests that verify the
supply’s specifications.
Location And Cooling
Figure 1 shows the outline shape and dimensions of the unit.
It is shipped ready for bench operation after connection to an
ac power source. The supply is air cooled. Sufficient space
should be allotted so that a free flow of cooling air can reach
the rear of the instrument when it is in operation. It should be
used in an area where the ambient temperature does not
exceed 40 degrees C. The current derates 1% per degree C
between 40
°
C-55
°
C.
Input Power Requirements
Depending on the line voltage option ordered, the supply is
ready to be operated from one of the power sources listed in
the Specification Table. The input voltage range, and the
input current and power at high line voltage and full load is
listed for each option.
Power Cord
This instrument is equipped with a three conductor power
cable. The third conductor is the ground conductor and when
the cable is plugged into an appropriate receptacle, the
instrument is grounded. The offset pin on the power cable
three prong connector is the ground connection. In no event
should this instrument be operated without an adequate cabi-
net ground connection.
The power supply was shipped with a power cord for the type
of outlet used at your location. If the appropriate cord was not
included, contact your nearest HP Sales Office to obtain the
correct cord.
