How to mount boards on a FC702S panel
You can mount the PNI800, IOB800, and the FB800
boards on the FC702S panel using the pillars, washers
and nuts that are supplied with the boards. The adapter
plate is supplied with the FC702S panel. A maximum of
three of these boards can be fitted. Ensure that you fit
the larger boards (such as the PNI800) before small
boards (IOB and FB800). Refer to Fig. 28 and complete
these steps:
1 The larger type of boards are supplied with a plastic
bezel that must be removed in this arrangement. To
do this, remove the two self-tapping screws that
secure this part.
2 If fitting a PNI800, connect the larger 64way connec-
tor of the ribbon cable to XP5 INT NBUS on the FC-
FI. Lead the cable across the mounting plate at the
back of the housing toward the PSU. Position the
cable so that it is not trapped between the mounting
pillars and the PCB.
3 Put the first board on top of the pillars provided (item
1 in Fig 28). Secure the board using washers and
screws if this is the only board being used, or a pillar,
if you are inserting more boards. If fitting a PNI800,
connect the 50way connector closest to the FC-FI to
the connector on the PNI800 PCB. If you fit a second
board of this type, use the next 50way connector for
this board.
4 If you are using one or more small boards (for exam-
ple, the IOB800 or FB800), use the adapter plate
supplied (item 3 in Fig. 28). Screw the adapter plate
into the last big board in the sequence, or directly
onto the back wall of the housing panel if there are
no larger boards. Use the washers and screws pro-
vided.
5 The smaller board can then be mounted on to the
adapter plate. Keep it in place using either a screw or
a pillar, if more boards are necessary. You can stack
up to three boards in total in this way
