RECAUTIONS
• Read this user’s manual to make sure of correct operation before starting installation, wiring, operation, maintenance, and
inspection of the FC4A series
MicroSmart
analog I/O modules
.
• 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 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 the power to the
MicroSmart
before starting installation, removal, wiring, maintenance, and inspection of the
MicroSmar 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.
• 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.
