Also check for suppliedaccessories,
and test
the electrical
performance
of the instrument,
using
the procedure
outlined in Paragraph 5-3.
If there is
damage or deficiency,
see the warranty on the inside
front cover of this manual.
2-3.
INSTALLATION.
2-4.
The Model 415E is fully transistorized; therefore
no special cooling is required.
However,
the instru-
ment should not be operated where the ambient tem-
perature exceeds 55°C (140°F).
2-5.
RACK
MOUNTING.
2-6.
The Model 415E is a submodular unit that when
used alone canbe bench mounted only. However, when
used in combination with other submodular units it can
be benchand/or rack mounted.
The hp combining case
and adapter frame
are designed specifically for this
purpose.
2-7.
COMBINING
CASE.
The combining case
is a
full-module
unit which accepts varying combinations
of submodular units.
Being a full-module unit, it can
be bench ог rack mounted analogous to any full-module
instrument.
An illustration of the combining case is
shown in Figure 2-1.
Instructions for installing the
Model 415E in a combining case are given graphically
in Figure 2-2.
2-8.
ADAPTER
FRAME.
The adapter frameis a rack
frame
that accepts
any combination
of sub-modular
units.
It can be rack mounted only. Ап illustration of
the adapter frame is given in Figure 2-3. Instructions
are given below:
a.
Placethe adapter frame on edge of benchas
shown
іп step 1, Figure 2-4.
b.
Stackthe sub-modularunits inthe frame as shown
in step 2, Figure 2-4.
Place the spacer clamps be-
tween instruments as shown in step 3, Figure 2-4.
c.
Place spacer clamps on thetwo end instruments
(see step 4, Figure 2-4) and push the combination into
the frame.
d. Insert screws oneither side of frame, andtighten
until sub-modular instruments are tight in the frame.
е.
The complete assembly is ready for rack mounting.

2-10.
To
protect
operating
personnel,
the National
Electrical
Manufacturers'
Association
(NEMA)
rec-
ommends
that
the instrument
panel and cabinet
be
grounded.
А11 Hewlett-Packard
instruments
are
02152-1
equipped with a three-conductor
power
cable which,
when plugged into an appropriate receptacle,
grounds
the instrument.
The
offest pin on the power
cable
three-prong connector is the ground wire.
2-11.
To preserve the protection feature
when орег-
ating the instrument
from a two-contact outlet, use a
three -prong to two-prong adapter and connect the green
pigtail on the adapter to ground.
2-12.
PRIMARY
POWER
REQUIREMENTS.
2-13.
The Model 415E can be operated from anAC or
DC primary power source. The AC source canbe either
115 or 230 volts, 50 to 400 cps.
TheDC sourceis a
24-volt rechargeable battery.
The rechargeable bat-
tery is supplied with option 01 instruments only.
2-14.
For operation from AC primary power, the in-
strument can be easily converted
from
115- to 230-
volt operation.
The LINE
VOLTAGE
switch,
51, а
two-position slide switch located at the rear of the in-
strument,
selects the mode of AC operation.
The line
voltage for which the instrument is set to operate ap-
pears onthe slider of the switch.
А 1/16-ampere,
250
volt fuse is used for both 115- and 230-volt operation.
CAUTION
DO NOT

The following applies to option 01 instruments
or instruments
that
have
