Installation instructions
Remove covers
NOTE. Right-side or left-side references in these instructions assume you are
viewing the instrument from the front panel.
WARNING. To avoid electric shock, switch off the instrument power, then
disconnect the power cord from the mains power. Failure to do so can cause
injury or death.
1. Remove the power cord.
2. If it is installed, pull the front cover off the instrument.
3. Remove the two T-15 Torx-head screws that attach the plastic carrying handle
to the side of the instrument. (It is not necessary to remove the black metal
handles.) (See Figure 1.)
4. Remove four T15 Torx-head screws along each side that attach the top and
bottom covers to the instrument, and two T20 screws near the front edge of
the top cover (next to the folding handles).
5. Remove the top and bottom covers. Remove the top cover by pulling it
straight back about 1 inch. Pull out on the sides of the top cover, flexing the
sides slightly to clear the instrument chassis, and pull the top cover away
from the instrument.
6. Turn the instrument over so it is resting on its top.
7. Remove the three T-15 Torx-head screws that attach the lower trim panel to
the chassis, and lift the lower trim panel from the instrument.
8. Remove the 18 T15 Torx-head screws that attach the internal bottom cover to
the chassis, and then lift the internal bottom cover away.

Installation instructions
Install Preamp option board (Options 50 and PFR50)
These options only apply to the RSA5103B and RSA5106B instruments.
1. Disconnect the semi-rigid cable connecting the ATT OUT connector to the
1ST CONV IN connector:
a. Loosen the semi-rigid cable connecting to the ATT OUT connector. Do
not pull the cable connector away from the ATT OUT connector.
b. Loosen the semi–rigid cable connecting to the 1ST CONV IN connector
completely. Rotate the semi-rigid cable upward. Now remove the
semi-rigid cable from the ATT OUT connector.

Installation instructions
2. Remove the two screws from the chassis and set aside for later reuse.
3. Remove semi-rigid feed-through cable from preamp assembly before
installing assembly. This allows access to the connectors below if needed.
a. Loosen one side (either side is okay) of the semi-rigid feed-through cable
so the nut turns easily.
b. Loosen the nut on the opposite end of the semi-rigid feed-through cable.
c. Pull on one end of the semi-rigid feed-through cable straight out from
the relay until the nut on the semi-rigid feed-through cable clears the
connector on the relay.
d. Loosen the opposite end of the semi-rigid feed-through cable and remove
the semi-rigid feed-through cable from the preamp assembly.
RSA5100B Series Options 50, PFR, PFR50 Upgrades 7

Installation instructions
4. Set the preamp assembly on the 1st Converter. Align the semi-rigid cables
with the ATT OUT and 1ST CONV IN connectors.
5. Use the two screws, previously set aside, to attach the preamp assembly to
the 1st Converter. Do not tighten the screws yet.
6. Screw the nuts on the end of the semi-rigid cables on to the ATT OUT
connector and 1ST CONV IN connector. Finger tighten the nut. If you
encounter any difficulty securing the nut to the connector, loosen the nut from
the connector and try connecting it again. It is critical that the alignment
between the semi-rigid cable and the connector be kept as straight as possible
to avoid possible calibration failure.
7. Tighten the screws securing the preamp assembly to the 1st Converter.
8. Torque the semi-rigid cable nut on the relay for the 1st Converter Out
connection to 10 in-lbs. Do not over-torque the nut. Stop tightening the nut as
soon as the torque wrench first “breaks”.
CAUTION. To avoid damaging the relay connector on the preamp assembly, be
careful not to touch the connector on the relay with the torque wrench while
tightening the nuts.
