Cut Key Slots for Modules
Sensor3 dimming and control modules are easily slid into place by hand. Each module slot
is keyed to accept only a module with the correct current rating for the slot.
Cutting Key Slots for 25A and 50A Modules
Modules with current capacities higher than 15A are prevented from fitting into incorrect
slots by the module cutout bar to the left of the rack. If you have supplied a configuration
chart to ETC these should be cut out correctly for you; otherwise you will have to cut the
bar on site.
Step 1: Ensure power to the rack is turned off and the modules are removed
Step 2: Locate which slots will be fitted with 25A and 50A modules
Step 3: Using a pair of large wire cutters, open the required notch in the bar
•
For 25A modules, open the top notch
• For 50A modules, open the bottom notch
C A U T I O N : Ensure that the metal swarf created by cutting the key slots does not cause any
shorting within the rack. Clean the rack after cutting key slots.
