NOTES:
1. Only red and black wires need be connected to power.
2. Be sure polarity is correct: RVFR "red., wire is positive (+), and "black" is negative.
3. Nominal voltage at red and black wires will be approximately 0.1 VDC.
4. See Note on Figure 3-1.
2-13. Alternate methods which provide effective protec­
tion for the i nstrument can also be used, however, the pre­
viously described method is considered the better one.

CAUTION
The Model 5065A has the negative side
of its power supply grounded. When
operating with auxiliary equipment such
as an external battery or clock, check to
ensure that the equipment can be con­
nected together.
2-16. LINE VOLTAGE. The Model 5065A can be oper­
ated from either 115- or 230-volt (±10%) ac power
lines. A slide switch on the rear panel permits quick
conversion for operation from either voltage. Insert a
narrow-blade screwdriver in the switch slot and set the
switch to expose the correct numbers to correspond
to the line voltage used (Table 2-1). The instrument is
supplied with a 115-volt fuse; change this fuse for
230-volt operation (Table 2-1).
IMPORTANT
Before connecting ac power to the
instrument, be certain slide switch is
properly positioned for 115 or 230 volt
operation.

2-17. POWER CABLE. The Model 5065A is equipped
with a detachable three-conductor power cable. In­
stall as follows:
a. Connect the round, three-conductor female
plug to the ac line jack on the instrument rear panel.
b. Connect male plug (two-blade with round
grounding pin) to three-conductor (grounded) outlet.
Exposed portions of the instrument are grounded
through the round pin for safety; when only two-
conductor outlets are available, use connector adapter
(HP Stock No. 1251-0048) and connect short wire from
adapter to a suitable ground.

2-19. Table 2-2 lists the Model 5065A front and rear
panel connectors and their respective mating con­
nectors. Not all connectors listed are shipped with the
instrument but are included in the table as useful
information for installation.
