ACC-72EX
Prior to installation, make sure that you have set the jumpers and address settings to your desired
requirements. Use the guide tracks that have been installed in the empty slots of your UMAC system
when installing a board.
As you slide the board into the rack, use caution to ensure none of the components on the board make
contact with the front plates of the boards on either side. Getting the front plate flush with the front of the
rack and turning the front screws firmly will ensure a good connection with the backplane.
When removing a board from the system, the user must first pull out any wired connections from the top,
bottom, and front panels then loosen the pem-nuts on the front of the rack. Next, the user can gently pull
the board from the rack and use caution to ensure that none of the components on the board make contact
with the boards on either side.
System malfunction can occur due to noise/chatter if the ACC-72EX
is placed outside of the recommended order as seen in the illustration
above. Note that the ACC-72EX is a Fieldbus device and should be
placed adjacent to the CPU, and as close as possible to ensure smooth
communication.
