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.
