Two power
transformers
(Tl) are available
for this
instrument, 100/1 15 vac or 1
15/230
vac.
On the rear panel
of each instrument
a decal indicates
the operating voltage
can be changed
by altering the wiring
configuration of the
transformer. To
change the operating voltage
of the
1
15/230
vac
transformer, refer
to paragraph 2-8.
Refer to
Figure
2-2
for changing
the
operating voltage
of the
100/115 vac power
transformer.
To
gain
access
to the
power transformer,
remove the
instrument’s top cover.
The
power
required to
operate the
instrument
is approximately
300 volt
amperes at full-load output.
2-8.
Should it
be necessary
to convert
the
instrument
from
115 to
230
volt
operation,
proceed
as follows.
Electrical changes
are shown
on the decal
on
the
underside
of the
top cover
and on
the schematic in
the
back
of this
manual.

INITIAL
OPERATION
2-10.
The following
procedure
is recommended
when
operating
the
Model
415B for the first
time after
ship-
ping
or a long
period
of idleness.
This
procedure will
minimize
the
possibility
of damage
resulting
from a
faulty
component.
a.
Connect
the line
plug to a
115 volts
ac power
source.
If the
instrument
has been wired
for
230
volt opera-
tion,
connect
to 230 volts
ac.
WARNING!
This instrument
is
equipped
with a
3-wire line
cord, one lead
of which is
connected
to the
metal chassis.
Connection
to a
properly-wired
outlet automatically
connects
the chassis
of the
instrument
to earth
ground. If an
adapter is
used to connect
the line
to a two-contact
outlet,
the
green lead extending
from the
adapter
should
be connected to
a
suitable
ground.
b.
Set the
HIGH VOLTAGE switch
to
STDBY/RESET.
c.
Set
the POWER switch to
ON.
The
ON
lamp will
illuminate. After
approximately
30
seconds, the
time-delay relay will
close
and
the
STDBY/RESET
lamp will illuminate.
d.
Set the
second
OUTPUT
VOLTAGE
dial to 500.
e.
After the
STDBY/RESET
lamp
illuminates,
set
the
HIGH VOLTAGE
switch
to ON.
Carefully
observe
if the
HIGH VOLTAGE
ON
lamp illuminates
and if
the panel meter
indicates
500
(±
15)
volts.
