Rackmount/Benchtop Versions—492/492P Service Vol. 1 (SN B030000 & up)
Fig. 6-3. Complete slide-out track assemblies.
5) position the instrument so the pivot screws (widest part
of instrument) are approximately even with the front rails;
6) adjust the alignment of the stationary sections according
to the procedure outlined in Fig. 6-7;
7) after the tracks operate smoothly, connect the power
cord to the power source;
8) push the instrument fully into the rack and latch.
9) Instruments are shipped with vinyl trim strips on the cabi­
net flange. These strips cover two holes in the flange that
can be used to insert screws to secure the rackmount cabi­
net to the rack frame. If you need the rackmounted instru­
ment secured better than the latches on each side provide,
cut out the vinyl cover around the hole with a sharp knife.
Install the securing screws as shown in Fig. 6-2A.
if the rackmount version is extended out of the rack
and tipped up to gain access to the bottom or back
panels of the instrument, it can swing past center and
fall back into the rack unless it is held. Use care when
doing this to avoid damaging the front pane! or equip­
ment that may be mounted above the 492/492P.
A lte rn a te R e ar M ounting M ethods
The following methods provide satisfactory mounting
under normal conditons; however, they do not provide
solid support for the rear of the instrument. If the in­
strument should be subjected to severe shock or vi­
bration consult your local Tektronix Field Engineer for
better rear support mounting information.
