If output relays or transistors in the SmartAXIS 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 SmartAXIS.
Connect a fuse to the output module, selecting a fuse appropriate for the load.
Use proper wires for output wiring.
UL1015 AWG22 or UL1007 AWG18
When equipment containing the SmartAXIS 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 SmartAXIS is destined for Europe.
When driving an inductive load that emits noise like a magnet or a valve, to reduce noise and protect circuits, use a
diode for the output on DC power type models and a surge absorber for the output on AC power type models.
Turn off the power to the SmartAXIS when wiring input/output terminals.
Emergency stop and interlocking circuits must be configured outside the SmartAXIS.
Use the input/output terminals within the SmartAXIS ratings and specifications.
Tighten mounting screws with torque of 0.5N·m (5 gf·cm).
