Rack Geography
Throughout this manual directions are given which refer to the front, back, left, and right
sides of the rack. For clarification, these references are detailed below.
Front - face of the rack with the dimmer modules and CEM.
Back - face of the rack with output and control connections (VEAM, DMX).
Left - when facing the front of the rack, this is the side to your left.
Right - when facing the front of the rack, this is the side to your right.
Preparation
Step 1: Use Sensor Configuration Editor and a SLTA if you wish to download and save
the current Sensor configuration out of the rack for later reference. For
information on this process contact ETC Technical Services (see page 1 ).
Step 2: Turn off the main breaker and disconnect all of the Cam-Lok ® connectors from
the touring rack.
Step 3: Remove the top eight or more dimmer modules from the rack. Note and
document the modules’ order/positioning in the rack for proper insertion and
configuration later.
Step 4: Use a digital voltmeter to VERIFY that power is off by checking voltages for all
combinations between the phase bars, neutral and ground.
Step 5: Remove the CEM from the rack.
Step 6: Remove the rack door in front of the CEM
by pushing down on the tab in the top
hinged corner.
Step 7: Remove the left side panel of the touring
rack (10 Phillips head screws) and set it
aside.
N o t e : You may find it necessary to remove the right side panel as well, depending on
your preferred method of performing some of the following steps. Feel free to do
so as needed.
