The Retrofit
Preparation
Step 1: Use Sensor Configuration Editor and a SLTA to download and save the current
Sensor configuration out of racks for later reference.
Step 2: Turn off the main breaker and disconnect all of the Cam-Lok® connectors from
the touring rack.
Step 3: Pull the modules out of the rack. Note and document the module’s
order/positioning in the rack for proper insertion and configuration later.
Step 4: Use a digital voltmeter and VERIFY that power is off by checking voltages for all
combinations between the phase bars, neutral and ground.
Step 5: Remove the rack door in front of the CEM
by pushing down on the tab in top hinged
corner.
Step 6: Remove the left side of the touring rack
(10 Phillips head screws) and set it aside.
Remove the Old
Step 1: Unscrew the dimmer output edge connectors from the backplane metal.
Step 2: Carefully feed the dimmer output ribbon cables through the backplane
individually. As you remove the ribbon cables, mark them with a permanent
marker them as illustrated above in the hexagons. There may be stickers on the
ribbon cables already, however these refer to cable length and not dimmer
outputs. They should not be used as a reference to these instructions.
Step 3: Examine each ribbon cable for any nicks or cuts due to backplane scrapes.
Step 4: Unscrew and remove the control data cable connector (J3) from the backplane
and feed it through the metal work.
Step 5: Unscrew the power edge connector (J1). Remove it from the backplane by
sliding it out of the notch in the rack and carefully pushing it through the
Note:
The order/layout of the dimmer output edge connectors is different on the CEM+
backplane.

backplane metal. This connector will be used in the upgrade.
Step 6: Unscrew the backplane metal from the rack. (One screw in each side upper-
corner - two screws total.) Discard these screws. Replacement screws with
thread locker are provided (ETC Part# HW377).
Step 7: Push the backplane towards the back of the rack to free the backplane side tabs
Step 8: Bend the sides into the center (out of the sides of the rack).
Step 9: Slide backplane metal forward in order to
allow easier working space while
removing data terminations.
Step 10: Finish removing the old backplane
metalwork. Discard the old backplane.
Control Input Panel Replacement
Step 1: From the open left side of the rack,
remove the control data ribbon cable from
the clips inside the rack.
Step 2: Remove the tour guides on the rear of the
rack by loosening (not removing) the
three screws behind each tour guide.
Once the screws are loose, slide the tour
guide toward the center of the rack to
remove it.
Step 3: Remove the two screws that hold in the
breaker on the left side of the control
panel.
Step 4: Remove the screw on each side of the old control input panel.
Step 5: Pull the control input panel out a couple inches.
a: Unplug the beacon connector (twisted red & black wire).
b: Completely pull the panel out of the rack.

Step 6: Connect the data cables
to the new control input
panel.
a: Insert the Ethernet
cable in the RJ45 jack
on the rear of the
control input panel.
b: Connect the new
control data ribbon
cable connector (the
connector is keyed - the
ribbon cable will go up)
in the new control input
panel ribbon cable
header. Both ends of
the control data
ribbon cable are the
same.
c: Connect the beacon
connector to either the
first or last pair of the
beacon header (show
here).
Step 7: Feed the cables into the rack where the control input panel will go and reinstall
the breaker with the same two screws. Be sure to note the proper on/off
orientation of the breaker to the panel labeling (The new panel and the old
panel are the same).
Step 8: Install the new control input panel in the rack. Leave the screw on each end of
the panel a bit loose for the next step.
Step 9: Reinstall the tour guides (under the screw heads still in the rack) and fully tighten
the screws for each side.

Power Termination
Step 1: Clip the first wire-tie behind the existing J1 power connector to give the harness
more room to move while you work.
Step 2: Install the power adapter harness to edge connector (straight thru PCB) to old
power connector (match the wire colors)
.
Step 3: Secure the power connectors together with provided 4"-wire-ties. Clip wire tie
ends for neatness.
Step 4: In line with where the backplane will go and all the way back of that sheet metal,
mount a sticky-back tie wrap mount.
Step 5: Use that tie wrap mount to loosely secure the power harness to the side of the
rack. Leave the tie wrap loose enough for the power harness to slide backwards
when the backplane is installed.
Data Cabling Preparation
Step 1: Identify the different dimmer output ribbon cable transition cards. An SP24 will
only use a single upper and lower card.
Note:
There are two different types. An “upper” card and a “lower” card. The transition
card is marked for both the type and which side is up when installed.
