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.
