INSTALLATION
2-1. INITIAL INSPECTION.
2-2. Mechanical Check.
2-3. If damage to the shipping carton is evident,
ask the carrier’s agent to be present when the in¬
strument is unpacked. Inspect the instrument for
mechanical damage. Also check the cushioning
material for signs of severe stress.
2-4. Performance Check.
2-5. The electrical performance of the Model
8447A or Model 8447A -001 should be verified
upon receipt. Repeat each test on each amplifier in
the Model 8447A -001 Dual Amplifier instrument.
Performance checks suitable for incoming inspec¬
tion are given in Sections IV, Performance Tests.
2-6. Claims for Damage.
2-7. If the instrument is mechanically damaged
in transit, notify the carrier and the nearest
Hewlett-Packard field office immediately. A list of
field offices is contained in the back of this man¬
ual. Retain the shipping carton and padding materi¬
al for the carrier’s inspection. The field office will
arrange for replacement or repair of your instru¬
ment without delay for claim settlements against
the carrier. Before shipment, this instrument was
inspected and found free of mechanical and electri¬
cal defects. If there is any deficiency, or, if electri¬
cal performance is not within specifications, notify
your nearest Hewlett-Packard sales and service
office.
2-8. PREPARATION FOR USE.
2-9. Power Requirements.
2-10. The Model 8447A or Model 8447A -001
operates from 115 or 230 volts ac line voltage at
any line frequency between 50 and 400 Hz. A slide
switch on the rear panel is set to the correct posi¬
tion for the line voltage available. A 0.5 ampere
line fuse is required for either 115 or 230 volt
operation.
2-11. Power Cable.
2-12. To protect operating personnel,
the Nation Electrical Manufacturers Association
(NEMA) recommends that the instrument panel
and cabinet be grounded. All Hewlett-Packard in¬
struments are equipped with a three-conductor po¬
wer cable which, when plugged into the appropri¬
ate receptical, grounds the instrument. The offset
pin on the power cables three-prong connector is
the ground wire.
2-13. To preserve the protection feature when
operating the instrument from a 2-conductor out¬
let, use a three-prong to two-prong adapter and
connector the green pigtail on the adapter to
ground.
2-14. The power cord or power input connector
meet the specifications established by the Interna¬
tional Electrotechnical Commission (IEC).
2-15. Operating Environment.
2-16. The operating range of the Model 8447A or
Model 8447 -001 is from 0°C to +55°C. The ampli¬
fier can be stored in a temperature range of -40° C
to +75°C.
2-17. Bench Mounting.
2-18. The Model 8447A is equipped with plastic
feet and tilt stand in place, ready for use as a bench
instrument.
2-19. Rack Mounting.
2-20. The Model 84 47 A may be rack mounted
by using an adapter frame. The adapter frame is a
rack frame that accepts any combination of sub-
modular units (see Figure 2-1). For additional in¬
formation, address inquires to your nearest HP
sales and service office.
