Removal of the Old Processor Module and Backplane
• Open the DE90 dimmer rack door, lift it off the hinges and carefully set it aside.
• Remove the inner metal panel. There are eight (8) #8-18 x 1/2" mounting screws (four (4) on
each side) that need to be removed. Once the screws are removed, carefully pull the metal
panel out and set it aside. Replacement mounting screws are provided to secure the panel
once the retrot is complete.
• If you are not familiar with the Strand DE90 dimmer rack processor electronics and wiring, it is
strongly advised that you take a few minutes to inspect the low voltage eld wiring connected
to analog inputs on top of the Processor Module (if applicable) and the connections on the
backplane. Some of this eld wiring may be reused to connect to the DE90-3000 retrot. Refer
to the Control Input/Output Connections (page 15) section of this manual for details.
• All of the internal OEM (Original Equipment Manufacturer) wiring must remain intact to complete
the retrot. Compare these connections to the ones on the DE90-3000 backplane. Do not
disconnect any wiring until you are completely satised with how easy this is going to be.
NOTE: Never pull directly on the wires to remove connectors.

• Disconnect the JP2 connector labeled “TO LOCAL PANIC BRACKET” from the backplane.
The entire panic bracket can now be removed. There are four (4) #10-32 mounting nuts
securing the bracket in place that need to be removed using a 3/8" nut driver. Once the nuts
are removed, the bracket can be pulled out and set aside.
• Disconnect all of the eld wiring connected to the top connectors on the backplane (JP1,
JP6, JP10 thru JP16 and JP18). These cables may be reused in some applications. Any
unused cables should be coiled up and wire-tied. Carefully set them aside inside the rack
and keep them isolated from any AC line voltage.
• Remove the Analog Input connectors (if applicable) from the top of the Processor Module.
These cables may be reused in some applications. Any unused cables should be coiled up
and wire-tied. Carefully set them aside inside the rack and keep them isolated from any AC
line voltage.
• Remove the two (2) screws located on each end of the processor module.
• Slide the processor module partially out (approximately 3" (75mm)) until you have enough
space to disconnect the control cables on the right-hand side (if applicable) and 3-Phase AC
Power Cable on the left-hand side.
Some of the control cables may be reused in some applications. Any unused cables should
be coiled up and wire-tied. Carefully set them aside inside the rack and keep them isolated
from any AC line voltage.
The 3-Phase AC Power Cable must be left intact and reconnected to the backplane on the
DE90-3000 retrot. Do not remove any of the wires from the connector.
• Slide the processor module out completely and set it aside.
• Disconnect the OEM fan power cables from JP5 connector located on the lower right-hand
side of the backplane. You will need a small at head screwdriver to loosen the connections
and pull the wires out. The OEM fan power cables will need to be reconnected to the
2-position breakaway connector on the backplane of the DE90-3000 retrot.
Inspect the fans and make sure they spin freely. Overheating of the dimmer modules is one
of the main causes of failure. Replacement fans are available from JSI upon request.
• Disconnect the OEM thermostat and power supplies cable from the JP8 connector. The
wires and connector must be left intact and reconnected to the backplane on the DE90-3000
retrot. Do not remove any of the wires from the connector. There is an OEM thermostat
located at the top of the rack and is wired in via this cable and connector. The thermostat
is a normally closed contact and opens at 185°F ±7°F (85°C ±4°C). The thermostat must
be left intact and operational for the DE90-3000 retrot to function properly. Replacement
thermostats are available from JSI upon request. There are two (2) OEM 12 Volt DC power
supplies located on right-hand side of the dimmer rack. The power supplies are used to
power the 24 Volt DC fans. The power supplies must be left intact and operational for the
DE90-3000 retrot to function properly. Replacement power supplies are available from JSI
upon request.
• Disconnect the two (2) OEM SSR control cables from the JP3 and JP4 connectors. Note
that the small 36" DE90 dimmer racks may only contain one (1) OEM SSR control cable
connected to JP3. Do not pull on the wire to disconnect. Carefully apply pressure to the
connector itself with either your ngers or preferably a small at head screwdriver. Do
not mix up the cable order or polarity. The wires and connector must be left intact and
reconnected to the backplane on the DE90-3000 retrot.
• The backplane should now be free and clear of any connections. Unscrew the ten (10) #6-32
x 1/4" mounting screws. Remove the backplane from the dimmer rack and set it aside.
• All of the electronics out of the dimmer rack present a great opportunity to do some
preventative maintenance. The rack should be thoroughly cleaned, vacuumed and sprayed
out using compressed air. All of the AC line and load connections should be inspected and
tightened if necessary.

#6-32 x 1/4" mounting screws provided.
• Terminate and connect the OEM fan power cables to the 2-position
breakaway JP5 connector provided located on the lower right-hand side
of the backplane. Be sure that the red wires go to the V+ terminal and the
black wires go to the V- terminal.
• Connect the OEM thermostat and power supplies cable to the 6-position
JP8 connector located on the lower right-hand side of the backplane.
A replacement connector has been provided in the event the OEM
connector has been damaged. Ensure all wire terminations are tight.
• Connect the two (2) OEM SSR control cables to the 18-position JP3 and
JP4 connectors located on the lower left-hand side of the backplane. If
the dimmer rack only contains one (1) OEM SSR control cable, connect it
to JP3. Be sure the cables are connected in the same order and polarity
in which they were disconnected. Extra care should be taken not to bend
or break any of the connector/header pins. Damage to these pins may
require replacement of the entire DE90-3000 backplane and will not be
considered warranty!
• Connect the OEM 3-Phase AC Power Cable to the JP7 connector located
at the lower center of the backplane. Ensure all wire terminations are tight
and the connector is fully seated with the correct polarity.
• Dress out, terminate and connect all other low voltage connections to the
backplane using the breakaway connectors provided. Be sure to isolate
and protect all shield wires. Refer to the Control Input/Output Connections
(page 15) section of this manual for details.
• All of the OEM and eld wiring connections should now be complete.
• Ensure the provided 26-conductor ribbon cable is connected to the User
Interface Board mounted on the DE90-3000 Front Panel (Faceplate).
• Ensure the provided 3-conductor cable is connected to the Front Panel
DMX-B Input receptacle located on the right-hand side of the DE90-3000
Front Panel (Faceplate).
• Ensure the provided 2-conductor cable is connected to the Panic Switch
located on the right-hand side of the DE90-3000 Front Panel (Faceplate).
• The DE90-3000 Front Panel (Faceplate) can now be installed in the
dimmer rack. Place the two (2) mounting holes on the right-hand side
over the studs that used to secure the panic bracket and nger-tighten on
the two (2) #10-32 locking nuts provided. Finger-start the two (2) #6-32
x 3/8” mounting screws provided in the locations that used to secure the
processor module. Once all the mounting hardware is in place they can be
tightened down.

• The inner metal panel can now be carefully set into place and secured
using the eight (8) #8-18 x 1/2" mounting screws provided. Two (2) #8
speed clips are provided to replace any missing or damaged.
WARNING! Never connect (turn on) power with inner metal panel removed.
• Connect (turn on) the power supply to the Strand DE90 dimmer rack.
• Verify the operation of the system status LED indicators, LCD display
and programming switches. Refer to page 18 to 20 for details.
• Refer to the programming section of this manual for system
conguration. Refer to page 22 to 37 for details.
• Test the system thoroughly to ensure all wiring terminations are
functioning.
• Verify all of the dimmer control outputs have the correct phase
referencing. If a dimmer control output is patched to the incorrect phase
reference, the dimmer will not dim correctly and will go to full output
at around 1% DMX input. The factory conguration for DE90-3000
Series retrot systems is for three-phase applications. The defaults
(DEFAULTS) menu is used to recongure the phase patch for standard
single-phase applications and the phase patch (Ø-PATCH) menu is
used to congure non-standard applications. Refer to page 31 and 36
for programming details. Refer to the charts on page 8 for the standard
dimmer to phase patch conguration for DE90 dimmer racks.
• Verify all dimmers are controlled sequentially. The Dimmer to Channel
Patch (DC-PATCH) will need to be modied (programmed) to
compensate for a mixture of single, dual and quad dimmer modules.
Refer to page 27 for programming details. Examples of DC-PATCH
congurations can be found on page 9 and 10. Charts used to
determine the DC-PATCH can be found on page 11 and 12.
• Verify fan operation. The fans are triggered on at 6% DMX input control,
and stay on as long as the DMX is at 6% or greater. When the DMX
input is brought down below 6%, there is a 5 minute timeout for the fans
to turn off. When the Panic Switch is turned on the fans turn on; when
the Panic Switch is turned off the fans turn off.
• Verify Front Panel (Faceplate) Panic Switch operation. When the Panic
Switch is turned on, all of the dimmer outputs are full-on.
• Verify Front Panel (Faceplate) DMX-B Input operation. The DMX B
LED will illuminate and the LCD will show the number of DMX channels
received.
• Once the DE90-3000 retrot system has been thoroughly tested the
dimmer rack door can be carefully set back on the hinges and closed.
