Output Wiring
Caution
If output relays or transistors in the MicroSmart CPU or output modules should fail, outputs may
remain on or off. For output signals which may cause heavy accidents, provide a monitor circuit
outside the MicroSmart.
Connect a fuse to the output module, selecting a fuse appropriate for the load.
Use proper wires for output wiring.
All-in-one type CPU modules:
UL1015 AWG22 or UL1007 AWG18
Slim type CPU and I/O modules:
UL1015 AWG22
When equipment containing the MicroSmart is intended for use in European countries, insert an
IEC 60127-approved fuse to each output of every module for protection against overload or
short-circuit. This is required when equipment containing the MicroSmart is destined for Europe.
