Safety
Please note the following safety warnings before use:
• Disconnect power from the enclosures before all maintenance.
Note:
Notes are helpful hints and information that is supplemental to the main text.
CAUTION:
A Caution statement indicates situations where there may be undefined or
unwanted consequences of an action, potential for data loss or an equipment
problem.
WARNING: A Warning statement indicates situations where damage may occur, people
may be harmed, or there are serious or dangerous consequences of an action.
WARNING: RISK OF ELECTRIC SHOCK! This warning statement indicates situations where
there is a risk of electric shock.
WARNING: RISK OF ELECTRIC SHOCK! Enclosures without an accessible power disconnect
device cannot be serviced safely. Before removing dimmer or control modules
for service, de-energize main feed to dimmer enclosure and follow
appropriate Lockout/Tagout procedures as described in NFPA Standard 70E.
It is important to note that electrical equipment such as enclosures can
present an arc flash safety hazard if improperly serviced. This is due to
available large short circuit currents on the feeders of the equipment. Any
work on energized equipment must comply with OSHA Electrical Safe
Working Practices.

The Retrofit 5
The Retrofit
Preparation
1: Use Sensor Configuration Editor and an SLTA (Serial LonTalk®Adaptor) if you want to download
and save the current Sensor configuration out of the enclosures for later reference. For
information on this process contact ETC Technical Services (see
Help from ETC Technical Services
on
page 2 ).
2: Turn off main power to the enclosure(s).
3: Remove all of the dimmer modules above the CEM (if retrofitting an SR or HSR 48 enclosure,
remove the eight modules below the CEM as well). Note and document the modules’ order/
positioning in the enclosure for proper insertion and configuration later.
4: Use a digital voltmeter to verify that power is “Off” by checking voltages for all combinations
between the phase bars, neutral and ground.
5: Remove the CEM from the enclosure.
WARNING: RISK OF ELECTRIC SHOCK! Enclosures without an accessible power disconnect
device cannot be serviced safely. Before removing dimmer or control modules
for service, de-energize main feed to enclosure and follow appropriate
Lockout/Tagout procedures as described in NFPA Standard 70E. It is
important to note that electrical equipment such as enclosures can present an
arc flash safety hazard if improperly serviced. This is due to available large
short circuit currents on the feeders of the equipment. Any work on
energized equipment must comply with OSHA Electrical Safe Working
Practices.

Remove the Old CEM
1: Mark the edge connector of each dimmer output ribbon cable (1, 2, 3, and 4) as illustrated below
in the hexagons. There may be stickers on the ribbon cables already; however, these may refer
to cable length and not dimmer outputs. They should not be used as a reference for these
instructions.
Note:
The order/layout of the dimmer output edge connectors is different on the CEM3
backplane.

The Retrofit 7
2: Document and/or label each wire that is currently landed on the J2 edge connector.
3: Unscrew the dimmer output edge connectors from the backplane metal.
4: Remove the ribbon cables from the cable clamp immediately above the CEM. For SR or
HSR 48 enclosures, also remove the ribbon cabling from the clamp immediately below the CEM.
5: Carefully feed the dimmer output ribbon cables through the backplane.
6: Examine each ribbon cable for any nicks or cuts that may have resulted from scraping against the
backplane.
7: Unscrew the power edge connector (J1). Remove it from the backplane by sliding it out of the
notch in the enclosure and carefully pushing it through the backplane metal. This connector will
be used in the upgrade.
8: Unscrew the backplane metal from the enclosure. (There are two screws total—one screw in the
upper corner of each side.) Discard these screws. Replacement screws with thread locker are
provided (ETC part# HW377) for later use.
9: Push the backplane toward the back of the enclosure to free the backplane side tabs.
10: Bend the sides toward the center (out of the sides of the enclosure).
11: Slide the backplane metal forward as far as the wires allow in order to allow easier working space
while removing data terminations.
Note:
If the power edge connector is damaged, the power harness will have to be replaced.
Contact ETC to obtain a replacement CEM3 harness.

Data Terminations
1: Unscrew the control data connector (J2) to release it from the backplane.
Transfer beacon wires
2: Remove beacon wires 5, 6, and 7 from the J2 connector using a precision 3/32"
(2.5 mm) flat-blade screwdriver. The wires are the beacon wires and will be
transferred to a new Phoenix connector that ships attached to the back of the new
CEM3 backplane. Carefully cut any zip ties that secure these wires to other wires
in the J2 connector or to the backplane.
3: Connect the three wires to the new Phoenix connector in the order shown at right
using a precision 3/32" (2.5 mm) flat-blade screwdriver. Pin 1 will be the top of the
connector in the new backplane.
4: Disconnect the DMXA wires from terminals 1, 2, and 3 of the J2 connector.
5: Connect the DMXA wires to an 8-pin connector using a precision 3/32” (2.5 mm) flat-blade
screwdriver. DMXA wires connect to the following terminals:
• J2-3 = (DMXA common)
• J2-1 = DMXA-2 (DMX-)
• J2-2 = DMXA-3 (DMX+).
Note:
Transfer DMX Wires
When transferring wire groups be sure to transfer all wire groups (except those
designated as ETCLink) to the new connectors separately to avoid confusion.
• In most cases stranded wire has been used for the data terminations. If so,
terminate the DMX wiring to the new connectors (found in the kit) in the same
manner as they were terminated to the old backplane. Double-up the DMXA
wiring to the same terminals as the DMXA pass-thru wires. (The DMX pass-thru
connector on the CEM3 backplane will not be used.)
• If Category 5 type cabling has been used for the DMX wire runs, IDC connectors
must be used (ordered separately) for the new terminations. Connect the DMXA
wires to an IDC connector and land the enclosure-to-enclosure jumper
connections on the separate “DMX PASS-THRU” connector (J12) on the new
backplane.
DMXA PASS-THRU: Common=1, Negative=2, Positive=3
DMXB PASS-THRU: Common=4, Negative=5, Positive=6
Note:
There are two different connectors available for CEM3 DMX data terminations.
One is for stranded wire as found in Belden 9729 and contains screw terminals
(ETC part# J3407-F included with the kits). The other style is an IDC connector
(ETC part# J3409-F must be ordered separately) for solid-core wire such as
Category 5 cabling.
CAUTION:
If using the IDC connector for Cat 5 solid-core wiring, you must start with
clean wire ends (clip the old punched end). Re-punching the old ends could
result in an intermittent or failed connection.
