Model 8660C
Installation
2-1. INTRODUCTION
2-2. This section provides information on in¬
coming inspection, selecting the input line voltage,
operating environment, and information applicable
to bench and rack mounted operation of the Model
8660C.
2-3. INITIAL INSPECTION
2-4. Inspect the shipping container for damage. If
the shipping container or cushioning material is
damaged it should be kept until the contents of the
shipment have been checked mechanically and
electrically. The contents of the shipment are
shown in Figure 1-1, and the procedures for
checking
electrical
performance
are
given
in
Section IV. If the contents are incomplete, if there
is mechanical dam^e or defects, or if the instru¬
ment does not pass the electrical performance test,
notify the nearest Hewlett-Packard office. If the
shipping container is damaged or the cushioning
material shows signs of stress, notify the carrier as
well as the Hewlett-Packard office. Keep the
shipping materials for the carrier's inspection. The
HP office will arrange for repair or replacement
without waiting for claim settlements.
2-5. The warranty statement for the instrument is
on the inside front cover of this manual. Contact
the nearest Sales/Service Office for information
relative to warranty claims.
2-6. PREPARATION FOR USE
2-7. Power Requirements.
2-8. The Model 8660C requires a power source of
100, 120, 220, or 240 volts +5%, -10%, 48-66 Hz.
Power consumption is approximately 400 VA
maximum.
2-9. Line Voltage Selection
CAUTION
To prevent damage to the
instrument
make the line voltage selection BEFORE
connecting the line power. Also ensure
the line power cord is connected to a
line power circuit that is provided with a
protective earth contact.
2-10. A rear panel line power module, (A7),
permits operation from 100,120, 220, or 240 Vac.
The number visible in the window (located on the
module) indicates the nominal line voltage to
which the instrument must be connected.
2-11. To prepare the instrument for operation,
slide the fuse compartment cover to the left (the
line power cable must be disconnected). Pull the
handle marked FUSE PULL and remove the fuse;
rotate the handle to the left. Gently pull the
printed circuit voltage selector card from its slot
and orient it so that the desired operating voltage
appears on the top-left side (see Figure 2-1).
Firmly push the voltage selector card back into its
slot. Rotate the FUSE PULL handle to the right,
install a fuse of the correct rating, and slide the
fuse compartment cover to the right.
NOTE
For 110-~120V line, use 4A slo-blo fuse, HP
Stock No. 2110-0635. For 220-240V line,
use 2A slo-blo fuse, HP Stock No. 2110-0303.
To avoid the possibility of injury or death,
the following precautions must be followed
before the Instrument is switched on:
a.
Note that the protection provided by
grounding the instrument cabinet may be lost
If any power cable other than the three¬
pronged type supplied is used to couple the
ac line voltage to the instrument.
b.
If this Instrument is to be energized via an
autotransformer to reduce or increase the line
voltage, make sure that the common terminal
is connected to the earthed pole of the power
source.
c.
The power cable plug shall only be inserted
into a socket outlet provided with a protec¬
tive earth contact. The protective action must
not be negated by the use of an extension cord
without a protective conductor (grounding).
d.
Before switching on the instrument, the
protective earth terminal of the instrument
must be connected to a protective conductor
of the power cord. This is accomplished by
ensuring that the instrument's internal earth
terminal is correctly connected to the instru¬
ment's chassis and that the power cord is
wired correctly.
