GROUNDING. This irtstrument la safely class I
equipment (lEC designation). All accessible con-
ductive parts are directly connected through the
grounding conductor of the power cord to the
grounding contact of the powar plug.
The powar input plug must only be inserted in a
mating receptacle with agrounding contact Do not
defeat the grounding connection. Any intenuption
of the grounding connection can create an electric
shock hazard.
For electric shock protectfon, the grouttding con-
nection must be made before making connection to
the instrument's input or output terminals
See Rg. 2*1. RefertothelinevoRage andfuse data label
on the rear panel.
Fuse Replacement
Turn the slotted section of the line fuse holder
counterclockwise and remove the fuse. Replace the fuse
with the proper type as shown on the rear panel label.
Cabling
Remove power cord before attempting cable in-
stallation.
For convenience, cabling from the front of the power
module to the rear par>el may be run through the air intake
and cable raceway as shown in Rg. 2>2. To install this
cabling first remove the access panel on the rear of the
power module. See Rg. 2-1. Next remove the two bottom
panel retainer screws and the bottom panel retainers.
Slide the bottom panel outfromtherearofthelnstrument.
Pass the cable through the front air Intake, across the
bottom of the plug-in support rails and out the access
panel. Replace the power module bottom cover.
To ensure proper cooling, do not operate the power
module with any cover removed.
Table Top Use
The power module may be operated with the front
raised. To raise the front of theinstrument extend the front
ball as shown in Rg. 2-3.
Rackmounting Instructions
Cooling. Examine the side panels of the TM 5006,
Option 10, power module. If there are no cooling holes in the
$i^ panels, at least 1-inch clearance must be maintairted
between the bottom of the power module artd the in-
strument below it. This is necessary to insure proper
cooling. If the side panels have cooling holes, no special
precautions are necessary.
If the rack has positive internal pressure for cooling
purposes, the mainframes must have aH compartments filled
with plug-ins or blank front panels (available from Tektronix,
Inc.) must be installed in the unused plug-in openings. If
greater interrtal air flow is desired in arelatively highly
pressurized rack, the grill opening at the bottom front of the
TM 5006 may also be blocked.
Rack Dimensions. The TM S(X>6. Option 10, is shipped
from the factory ready for rack mounting. Rgure 2-4 shows
major dimensions. Rture 2-5 shows the spring-latch cutout
in the stationary section.
NOTE
The slide tracks supplied with the TM 5006, Option
10, have holes in the stationary sections to
accomodate the spring latches. The TM 5006, Option
10. should not be mounted with rack slides that do not
have the rack-latch holes.
The TM 5006, Option 10, fits the standard 19-inch side
cabinet, rack or console. Spacing inside the flt}nt rails must
be at least 17 3/4 inches. This allows clearance for the
stationary section of the slideout backs to permit the
assembly to slide freely on the sikMxjt tracks.

The slide-out tracks, with existing hardware supplied,
will conveniently mount in any rack with the front and rear
rails spaced Irom 10 1/2 inches to 24 1/2 inches.
Mounting the Slide Tracks. Locate the proper rack
holes tor mounting as shown in Fig. 2-6. Notice that the
hole spacing in the racks varies. When installing theslides
In the EIA type racks, make certain the slides are attached
to the 1/2-inch spaced holes. Figure 2-6also shows details
for determining position of the slides in the rack. Mount
the rails using enclosed hardware as shown in Figs 2-7
and 2-6. rigures2-8BandCshow rail-mounting details for
deep and shallow racks Make sure the stationary sections
are horizontally aligned so they are level and parallel with
each other.
Installing the TM 5006. Option 10, In the Rack Slides.
Make certain all plug-ins are removed from (he power
module Pull the slide-out track intermediate sections out
as far as they will go See Fig 2-9. insert the instrument
chassis sections into the intermediate section and push
the instrument forward until the instrument chassis sec-
tion locks into the intermediate section. Now press both
buttons protruding from the stop-latch holes in the
intermediate sections while pushing the instrument The
instrument can now be pushed Into the rack, cabinet, or
console. The latches holding the intermediate sections to
the stationary sections are automatically operated by the
instrument as it is pushed into the rack or cabinet. The
quick-release latches automatically engage the rack-latch
holes in the stationary sections of the rails as the
instrument is pushed fully into the rack.
Removing the Instrument. Remove all plug-ins Irom
power module Unscrew the two thumb saews at the top
of the front panel Pull the rectangular latches on both
sides of the front panel. Using the latches pull the
instrument from the enclosure until the slide intermediate
sections latch with the instrument sections and the
stationary sections The instrument is firmly held In this
position To completely removethe instrument, press both
release-latch buttorts visible in the stop-latch holes and
carefully slide the instrument from the rack or cabinet.
Rack Adjustments. After installing the instrument In the
rack, binding in the rack slides may occur if the slides are
not properly adjusted. Slide the instrument from the rack
until the front panel is about 10 inches from the front of the
rack. Slightly loosen the screws holding the right and left
tracks to the front rails. Allow the tracks to seek their
normal position. Retighten the screws and check the
tracks for smooth operation by sliding the instrument in
and out of the rack.

NOTE
The DC SOS. DC SOSA and LAS01 Wplug-ins are not
compatible with this power module.
Check to see that the plastic barriers on the inter-
connecting jack of the selected power module compart-
ment match the cutouts in the plug-in circuit board edge
connector The right-most compartment isthe high power
compartment. Align the plug-in chassis with the upper and
lower guides (see Fig. 2-10) of the selected compartment.
Push the plug-in chassis in and press firmly to seat the
circuit board edge connector in the Interconnecting jack.
Turn the power module on.
Family Compatibility
Mechanically. TM 5000 plug-in modules are very
similar to other Tektronix product families. However, they
are not electrically compatible Therefore, the TM 5006
interface has barriers on the mating connectors between
pins 6and 7to ensure that incompatible plug-ins cannot
be inserted. SeeFig. 2-11- Acompatible module will have a
matching slot between pins 6and 7of its main circuit
board edge connector. This slot and barrier combination
is the primary keying assignment.
Customizing the Interface
The modularity of this instrumentation system provides
lor many different functions to be performed by the plug-
in modules. Specificfunctionsare grouped intof amilles or
classes, of which there may be several plug-in module
members. For instance, some classes are Power Supplies.
Signal Sources, Measurement, and soforth. Each modular
member of afunctional family will have asecond slot,
peculiar to its family assignment, located in Its edge
connector. The TM 5006 user can select one or more
