Change out the AF Cards (if present)
If your rack supports Advanced Features (AF) you will need to replace the AF cards as well.
AF cards are located on the right side of the dimmer module slot between the copper
neutral busses and the dimming circuitry cards.
To replace the AF cards:
Step 1:
Remove the old AF cards by flipping the white
retainer tab on the cards into the down
position.
Step 2:
Pull the old cards out of the slots.
Step 3:
Set the DIP switches on the new cards
according to the chart below. Only the first two
DIP switches are used.
Step 4:
Slide the new AF cards completely into the
vacant slots starting with card #1 in the top.
The number of cards depends on rack size.
Step 5:
Flip the white tab up to lock the new card in
place.
N o t e :
You cannot use the old screws without the additional shoulder-sleeve as they will
block the CEM3 from being fully inserted.
