and found free of mechanical and electrical defects.
If there is any deficiency, or if electrical performance
is not within specifications, notify your nearest
Hewlett-Packard Sales and Service Office.
2-11. STORAGE AND SHIPMENT
2-12. PACKAGING. To protect valuable electronic
equipment during storage or shipment always use the
best packaging methods available,
Your Hewlett-
Packard field office can provide packing material such
as that used,for original factory packaging. Contract
packaging companies in many cities can provide de-
pendable custom packaging on short notice. Here are
a few recommended packaging methods :
a. RUBBERIZED HAIR.
Cover painted surfaces
of instrument with protective wrapping paper.
Pack instrument securely in strong corrugated
container (350 lb/sq in. bursting test) with 2-
inch rubberized hair pads placed along all sur-
faces of the instrument. Insert fillers between
pads and container to ensure a snug fit.
b. EXCELSIOR. Cover painted surfaces of instru-
ment with protective wrapping paper. Pack in-
strument in strong corrugated container (350 lb/
sq in. bursting test) with a layer of excelsior
about 6 inches thick packed firmly against all
surfaces of the instrument.
2-13. ENVIRONMENT. Conditions during storage
and shipment should normally be limited as follows:
a. Maximum altitude, 20,000 feet
b. Minimum temperature, -40” F (-40” C)

POWER CONNECTION
LINE VOLTAGE. The Model 4342Aoperates
either 115 or 230 volt (*lo%) ac line voltage
and Line frequency from 50 to 400Hz. A slide
switch on the rear panel permits quick conversion for
operating from either voltage. Insert a narrow- blade
screwdriver in the switch slot and slide the switch
to
the right for 115-volt operation (“115” marking ex-
posed) or to the left for 230-voltoperation (“230” mar-
king exposed). The Model 4342A is supplied with 115-
volt fuse; for 230-volt operation, be sure to replace
this fuse with that listed in Table 2-I.

To avoiddamage to theinstrument, before
connecting the power cable, set the 115/
230-volt switch for the line voltage to be
used.
2-16. POWER CABLE, To protect operating per-
sonnel, the National Electrical Manufacturers Associ-
ation (NEMA) recommends that instrument panels and
cabinets be grounded. Accordingly, the Model 4342A
is equipped with a detachable three.-conductor power
cable which, when plugged into an appropriate recepta-
cle, grounds panel and cabinet. The offset pin of the
three-prong connector is the ground pin. Proceed as
follows for power cable installation.
a. Connect flatplug (3-terminal connector) to LINE
jack at rear of instrument.
b. Connect plug (a-blade with round grounding pin)
to J-wire (grounded) power outlet. Exposed
