RECAUTIONS
• Read this user’s manual to make sure of correct operation before starting installation, wiring, operation, maintenance, and
inspection of the
MICRO
3
.
• All
MICRO
3
’s are manufactured under IDEC’s rigorous quality control system, but users must add a backup or failsafe pro-
vision to the control system using the
MICRO
3
in applications where heavy damage or personal injury may be caused in
case the
MICRO
3
should fail.
• In this user’s manual, safety precautions are categorized in order of importance to Warning and Caution:
• Turn power off to the
MICRO
3
before starting installation, removal, wiring, maintenance, and inspection on the
MICRO
3
.
Failure to turn power off may cause electrical shocks or fire hazard.
• Special expertise is required to install, wire, program, and operate the
MICRO
3
. People without such expertise must not use
the
MICRO
3
.
• 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.
• Install the
MICRO
3
according to instructions described in this user’s manual. Improper installation will result in falling, fail-
ure, or malfunction of the
MICRO
3
.
•
MICRO
3
is designed for installation in equipment. Do not install the
MICRO
3
outside of equipment.
• Install the
MICRO
3
in environments described in this user’s manual. If the
MICRO
3
is used in places where the
MICRO
3
is
subjected to high-temperature, high-humidity, condensation, corrosive gases, excessive vibrations, and excessive shocks,
then electrical shocks, fire hazard, or malfunction will result.
• The pollution degree of the
MICRO
3
is “Pollution degree 2.” Use the
MICRO
3
in environments of pollution degree 2 (accord-
ing to IEC664-1).
• All DC power type
MICRO
3
units are “PS2” type (according to EN61131).
• Prevent the
MICRO
3
from falling while moving or transporting the
MICRO
3
, otherwise damage or malfunction of the
MICRO
3
will result.
• Prevent metal fragments and pieces of wire from dropping inside the
MICRO
3
housing. Put a cover on the
MICRO
3
during
installation and wiring. Ingress of such fragments and chips may cause fire hazard, damage, or malfunction.
• Use a power supply of the rated value. Use of a wrong power supply may cause fire hazard.
• Use wires of a proper size to meet voltage and current requirements. Tighten M3 terminal screws to a proper tightening
torque of 0.3 to 0.5 N-m.
• 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 IEC127-approved fuse on the output circuit. 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.
• Make sure of safety before starting and stopping the
MICRO
3
or when operating the
MICRO
3
to force outputs on or off.
Incorrect operation on the
MICRO
3
may cause machine damage or accidents.
• 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
.
• Do not connect to the ground directly from the
MICRO
3
. Connect a protective ground to the equipment containing
MICRO
3
using an M4 or larger screw. This is required when exporting equipment containing
MICRO
3
to Europe.
• Do not disassemble, repair, or modify the
MICRO
3
.
• Dispose of the battery in the
MICRO
3
when the battery is dead in accordance with pertaining regulations. When storing or
disposing of the battery, use a proper container prepared for this purpose. This is required when exporting equipment con-
taining
MICRO
3
to Europe.
• When disposing of the
MICRO
3
, do so as an industrial waste.
• Dispose of the battery in the memory card when the battery is dead in accordance with pertaining regulations.
