RECAUTIONS

• Read this user’s manual to make sure of correct operation before starting installation, wiring, operation, maintenance, and

inspection of the

MicroSmart

• All

MicroSmart

modules are manufactured under IDEC’s rigorous quality control system, but users must add a backup or

failsafe provision to the control system when using the

MicroSmart

in applications where heavy damage or personal injury

may be caused in case the

MicroSmart

should fail.

• In this user’s manual, safety precautions are categorized in order of importance to Warning and Caution:

• Turn off power to the

MicroSmart

before starting installation, removal, wiring, maintenance, and inspection of the

Micro-

Smar t

. Failure to turn power off may cause electrical shocks or ﬁre hazard.

• Special expertise is required to install, wire, program, and operate the

MicroSmart

. People without such expertise must not

use the

MicroSmart

• Emergency stop and interlocking circuits must be conﬁgured outside the

MicroSmart

. If such a circuit is conﬁgured inside

the

MicroSmart

, failure of the

MicroSmart

may cause disorder of the control system, damage, or accidents.

• Install the

MicroSmart

according to the instructions described in this user’s manual. Improper installation will result in fall-

ing, failure, or malfunction of the

MicroSmart

• The

MicroSmart

is designed for installation in a cabinet. Do not install the

MicroSmart

outside a cabinet.

• Install the

MicroSmart

in environments described in this user’s manual. If the

MicroSmart

is used in places where the

MicroSmart

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 environment for using the

MicroSmart

is “Pollution degree 2.” Use the

MicroSmart

in environments of pollution

degree 2 (according to IEC 60664-1).

• Prevent the

MicroSmart

from falling while moving or transporting the

MicroSmart

, otherwise damage or malfunction of

the

MicroSmart

will result.

• Prevent metal fragments and pieces of wire from dropping inside the

MicroSmart

housing. Put a cover on the

MicroSmart

modules during installation and wiring. Ingress of such fragments and chips may cause ﬁre hazard, damage, or malfunc-
tion.

• Use a power supply of the rated value. Use of a wrong power supply may cause ﬁre hazard.

• Use an IEC 60127-approved fuse on the power line outside the

MicroSmart

. This is required when equipment containing

the

MicroSmart

is destined for Europe.

• Use an IEC 60127-approved fuse on the output circuit. This is required when equipment containing the

MicroSmar t

is des-

tined for Europe.

• Use an EU-approved circuit breaker. This is required when equipment containing the

MicroSmart

is destined for Europe.

• Make sure of safety before starting and stopping the

MicroSmart

or when operating the

MicroSmart

to force outputs on or

off. Incorrect operation on the

MicroSmart

may cause machine damage or accidents.

• If relays or transistors in the

MicroSmart

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

• Do not connect the ground wire directly to the

MicroSmart

. Connect a protective ground to the cabinet containing the

MicroSmart

using an M4 or larger screw. This is required when equipment containing the

MicroSmart

is destined for

Europe.

• Do not disassemble, repair, or modify the

MicroSmart

modules.

• Dispose of the battery in the

MicroSmart

modules 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 equipment
containing the

MicroSmart

is destined for Europe.

• When disposing of the

MicroSmart

, do so as an industrial waste.

Warning

Warning notices are used to emphasize that improper operation may cause
severe personal injury or death.

Caution

Caution notices are used where inattention might cause personal injury or
damage to equipment.
