DC Source Input (DC Power Type)
Warning
• Emergency and interlocking circuits must be configured outside the MICRO
3
. If such a circuit is
configured inside the
MICRO
3
, failure of the MICRO
3
may cause disorder of the control system,
damage, or accidents.
Caution
• Use a power supply of the rated value. Use of a wrong power supply may cause fire hazard.
• Use an IEC127-approved fuse on the power line outside the MICRO
3
. This is required when
exporting equipment containing MICRO
3
to Europe.
• Use an EU-approved circuit breaker. This is required when exporting equipment containing
MICRO
3
to Europe.
• Do not connect to the ground directly from the MICRO
3
. Connect a protective ground to the equip-
ment containing MICRO
3
using an M4 or larger screw. This is required when exporting equipment
containing MICRO
3
to Europe.
• If relays or transistors in the MICRO
3
output circuit fail, outputs may remain on or off. For output
signals which may cause heavy accidents, provide a monitor circuit outside of the MICRO
3
.
• Use an IEC127-approved fuse on the output circuit. This is required when exporting equipment
containing MICRO
3
to Europe.
