!Caution Leave the protective label in place while wiring. The Unit may malfunction if
strands of wire get inside the Unit. After completing wiring be sure to remove
the label to avoid overheating.
I/O Line Noise Do not run CPM2C-S I/O lines in the same duct or conduit as power lines.
!Caution If flat cables are connected for more than one CompoBus/S network, interfer-
ence between the flat cables can cause unstable operation. If you are using
more than one network, be sure the flat cables are separated by at least
5 mm.
