PROCEDURE
Before you start . . .
1 . Check the rear panel markings . If the factory settings are compatible with
the available line voltage and frequency, insert
the desired plug-ins . Use the bail to raise the front of the instrument .
2 .
If a
change
is
needed, follow these steps :
a . Line Selector Block(s)
Remove the four hold-down screws on the top of the dust cover cabinet and lift the
cabinet off . This gives easy access
to the Line Selector blocks located on the main circuit board .

Installation
Procedure-TM 506
The rackmount version of
the TM 506 Power Module is
designed
for operation in a standard 19-inch wide
rack
that has Universal, EIA, RETMA, or
Western Electric hole
spacing . When properly
mounted, this instrument will
meet all electrical and
environmental specifications given
in Section
1 .
Mounting Method
This instrument
will fit most 19-inch wide racks
whose
front and rear holes conform to Universal hole
spacing ;
some drilling may be required on racks
having EIA,
RETMA, or Western Electric hole
spacing . The slide-out
tracks easily mount to the cabinet
rack front and rear
vertical
mounting rails if the inside distance between
the
front

and

rear

rails

is

within

10 9/16 inches

to
24 3/8 inches .

If

the

inside

distance

exceeds
24 .3/8 inches, some
means of support is required for the
rear ends of the
slide-out tracks . (For example, make
extensions
for the rear mounting brackets .)
RackDimensions
Height . At least 5 1/4 inches of
vertical space is re-
quired to mount this
instrument in a rack : If other
instruments are
operated in the rack, an
additional
1/4 inch is required, both above and below
the TM 506, to
allow space for proper circulation of cooling
air .
Width
. A standard 19 inch wide rack may be used .
The
dimension of opening between the
front rails mustbe at
least 17 5/8 inches for a cabinet in which
the front lip of
the stationary section is
mounted behind an untapped
front rail as shown
in Fig . 0-2A . If the front rails aretapped,
and the
stationary section is mounted in front of the
front
rails as shown in Fig . 0-2B, the dimension
between the
front rails should be at least 17 3/4 inches .
These dimen-
sions allow room on each
side of the instrument for the
slide-out
tracks to operate so the instrument can move
freely in and out of the rack .
Depth . For proper circulation of
cooling air, allow at
least two inches clearance behind the
rear of the instru-
ment andany enclosue on
the rack .
Installing the
Slide-Out Tracks
The
slide-out tracks for the instrument consists
of two
assemblies, one for the left side of the instrument
andone
for the right side . Each assembly
consists of three
sections . A stationary
section attaches to the front and
rear rails of
the rack ; the frame section installed at
the
factory
attaches to the instrument and the
intermediate
section fits between the other two
sections to allow the
instrument to fully extend
out of the rack .
0- 3
RACKMOUNTING
Hardware . The small hardware
components included
with the slide-out track
assemblies are used to mount
the
tracks to most standard
19-inch vertical rack rails
having
this compatibility .
NOTE
1 .

Front and rear rail holes
mustbe large enough to
allow inserting a 10-32
screw through
the rail
mounting hole
if the rails are untapped
(see Fig . 0-
1A) .
2 .
Or, front and rear rail holes
must be tapped to
accept a 10-32 screw if
Fig . 0-18mounting method is
used . Ncte in Fig . 0-18
right illustration that a No .
10
washer (not supplied)
may be added to
provide
increased
bearing surface for the slide-out
track
stationary
section front flange .
Because of the above
compatibility, there will be some
small parts left over .
The stationary and
intermediate
sections for both
sides of the rack are
shipped as a
matched
set and should not be
separated . The matched
sets of
both sides including hardware
are marked 351-
0195-00
on the package . To
identify the assemblies,
note
that the automatic
latch and intermediate section
stop is
located near
the top of the matched set
.
Mounting
Procedure . Use the
following procedure to
mount both sides . See Fig .
0-1 for installation details .
1 . To mount
the instrument directly
above or below
another
instrument in a cabinet
rack, select the ap-
propriate holes in the front
rack rails for the stationary
sections, using Fig . 0-2 as a
guide .
2 .

Mount the stationary slide-out
track sections to the
front
rack rails using either of
these methods :
(a)

If the front flanges of
the stationary sections
are to
be mounted
behind the front rails (rails
are counter-
sunk
or not tapped), mount
the stationary sections as
shown in Fig . 0-2A, right
illustration .
(b)

If the front flanges of the
stationary sections are to
be
mounted in front of the
front rails (rails are tapped
for 10-32 screws) mount
the stationary sections as
shown in Fig .
0-1B, right illustration . To
provide
increased bearing surface
for
the screw head to
securely fasten the front
flange to the rails, a flat
washer
(not supplied)
may be addedunder the screw
head .

However,
if this mounting method is used, the front
panel will not fit flush against the front rail because of
the stationary section andwasher thickness .
If
aflush
fit is preferred, method 1(a) should be
used .
3 . Mount the stationary slide-out sections to
the rear
rack rails using either of these methods
.
(a)

If the rear rack rail holes are not tapped to
accept
10-32 machine screws,
mount the left stationary sec-
tion with hardware
provided as shown in the left or
center illustration of Fig . 0-1A . Note that the rear
mounting bracket can be installed either
way so the
slide-out tracks will fit a deep or
shallow cabinet rack .
Installation Procedure-TM 506
Use Fig . 0-1A
as a guide for mounting the right
stationary
section . Make sure that the stationary
sec-
tions are horizontally aligned so they
are level and
parallel with each other
.
(b)

If the rear rack rail holes
are tapped to accept 10-32
machine
screws, mount the left stationary section
with
hardware provided as shown in the left or center
illustration of Fig . 0-1B . Note that the rear
mounting
bracket can be installed either way so
the slide-out
tracks will fit a deep or
shallow cabinet track . Use Fig . 0-
1 B as a guide
for mounting the right stationary section .
Make sure the stationary sections are horizontally
aligned so they are level and parallel with each
other .

TM 506 Installation and Adjustment
follows :
To insert the instrument
into the rack, proceed as
1 .

Pull the slide-out track intermediate
sections out to
the fully extended position .
2 . Insert the instrument chassis
sections into the
intermediate
sections .
3 . Press the stop
latches on the chassis sections and
push the instrument
toward the rack until the
latches snap
into
their holes .
4 . Again press the stop
latches and push the
instru-
ment into
the rack .
To secure the instrument
front-panel to the rack, the
rack must either have
universal hole spacing, or a hole
mustbe
drilled and tapped for a 10-32 screw, see
Fig . 0-2 .
Using the hardware (not furnished) indicated
in Fig . 0-2,
secure the TM 506 to the front
rails of the rack .
Slide-Out TrackMaintenance
Installation Procedure-TM
506
To adjust the slide-out
tracks forsmooth sliding action,
loosen thescrews
used to join the stationary sections to
the rails of
the rack . Center the instrument,
allowing the
slide-out tracks to seek the proper
width, then tighten the
screws .
The slide-out tracks require no
lubrication . The special
dark gray finish on
the sliding parts is a permanent
lubrication
.
