16 Sensor3 CE Rack (ESR3) Installation Manual
Converting Neutral Disconnect Slots
There are two classes of modules available for Sensor3 CE racks - modules which break
the neutral, such as RCD or ND modules, and single pole modules that do not. Normally
your rack will be configured by ETC at the factory for the correct module types, however if
you have a mixture of modules or you have not been able to supply details of slot
allocations you may need to configure some slots on site.
Step 1: Determine which dimmer slots you will be converting. You can convert either
individual slots or a three-slot strip at a time.
Step 2: Gently bend the neutral lug retraining tab out with a
small flat blade screwdriver until the lug releases and
you are able to pull it out. See Figure 15.
Step 3: Use a flat blade screwdriver to loosen the threaded
inserts until the contact plates can slide out of both
lugs.
Step 4: Repeat Step 2 and Step 3 for the other dimmer slot
lug.
Step 5: Install a Neutral lug jumper into the lugs and tighten
the threaded inserts.
Step 6: Slide the jumpers into the plastic lug strip until the lug tab clicks into place.
Step 7: Secure the jumper to the thread on the Neutral bus bar using the provided
M3x8mm screw.
Repeat Steps 1 through 6 for any other lugs you want to convert
C A U T I O N : Lug catches will break if bent too far. Only bend the
catch until the lug releases.
Figure 15: Removing a lug
Use a small flat screwdriver
to lift the lug tab enough to
release the lug from the strip
and pull it out.
