The Retrofit
Preparation
Step 1: Use the Sensor+ Connect web interface to download and save the current
configuration out of the pack for later reference. Instructions on saving your
configuration from this interface can be found in any CEM+ Software Release
Note or any CEM+ Configuration Manual available for download from the ETC
website (www.etcconnect.com
).
Step 2: Disconnect all of the Cam-Lok
®
connectors and data connections from the
portable pack.
Step 3: Remove the dimmer modules from the pack. Note and document the modules’
order/positioning in the pack 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 CEM+ from the pack.
Step 6: Remove the pack door using a #2 phillips-head screwdriver.
Step 7: Remove the four black side covers. They are held in place by 24 5/32” allen
screws (three on each corner of the pack, on both the top and bottom).
Note:
If your pack has the Cam-Lok pass thru option, the side panels are secured at the
bottom with extra long hex head bolts. These are in place of the bottom allen
screws and require a 7/16” socket to remove.
