Connecting the 4253 I/O module
External connections are made to the Controller via cables which can
enter through holes in any part of the case using the knockouts
provided. Cables connecting to modules plugged into the
motherboard should be routed to each side of the chassis plate where
there are cable guides provided. This ensures modules can be
removed easily without cables snagging.
All connections to the module are made to the strip of green
connectors along the front edge of the module circuit board. The
connectors can be unplugged from the module so you can gain access
to the screw terminals with a screwdriver. Unplugging the connectors
also enables the module to be removed at a later date, leaving the
wiring intact.
