The
following
paragraphs
describe various
conditions that should be considered before
operating
the
732A. If the 732A is brand new, set the rear panel

Input Power
Requirements
2-1
5. The 732A is designed to
be
powered
continuously
(including
storage
or shipment) to
maintain
standardization. Normally,
power is continuously
applied, either to the ac line input
connector
or to the low
voltage
ac
or
dc input
connectors.
The ac
line
power
requirements are:
lOOV,
120V, 220V
or
240V
ac±
10%,
at
50
or
60
Hz. Low voltage, 24-40V
dc or
24-30V
ac,
50-400
Hz
may be connected
to supply instrument
power
and
charge the internal backup battery through
connectors
on
the rear panel. The internal, rechargeable
gell-cell
(sealed,
gelled
electrolyte
lead-acid)
battery
provides
approximately 12 hours of continuous
operation
when
ac
power
is not available.
2-16.

For ac line
voltages
from
iOOV
to 120V use
a
3/

fuse.
Forac line voltages from
220V
to
240V
use a
I/4A
Slow-Blow
