RECAUTIONS

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

inspection of the

MicroSmart

AS-Interface master module.

• All

MicroSmart

AS-Interface master modules are manufactured under IDEC’s rigorous quality control system, but users

must add a backup or failsafe provision to the control system using the

MicroSmart

AS-Interface master module in appli-

cations where heavy damage or personal injury may be caused in case the

MicroSmart

AS-Interface master module should

fail.

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

• Turn off the power to the

MicroSmart

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

MicroSmar t

AS-Interface master module. Failure to turn power off may cause electrical shocks or fire hazard.

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

MicroSmart

AS-Interface master module. People

without such expertise must not use the

MicroSmart

AS-Interface master module.

• 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

AS-Interface master module according to the instructions described in this user’s manual. Improper

installation will result in falling, failure, or malfunction of the

MicroSmart

AS-Interface master module.

• The

MicroSmart

AS-Interface master module is designed for installation in a cabinet. Do not install the

MicroSmart

AS-

Interface master module outside a cabinet.

• Install the

MicroSmart

AS-Interface master module in environments described in this user’s manual. If the

MicroSmart

AS-Interface master module

is used in places where the

MicroSmart

AS-Interface master module is subjected to high-tem-

perature, 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

AS-Interface master module is “Pollution degree 2.” Use the

MicroSmart

AS-

Interface master module in environments of pollution degree 2 (according to IEC 60664-1).

• Prevent the

MicroSmart

AS-Interface master module from falling while moving or transporting the

MicroSmart

AS-Inter-

face master module, otherwise damage or malfunction of the

MicroSmart

AS-Interface master module will result.

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

MicroSmart

AS-Interface master module housing.

Put a cover on the

MicroSmart

AS-Interface master module 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 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.

• 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.

• When disposing of the

MicroSmart

modules, 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.
