Introduction
This chapter describes the methods and precautions for installing and wiring
MicroSmart
modules.
Before starting installation and wiring, be sure to read “Safety Precautions” in the beginning of this manual and under-
stand precautions described under Warning and Caution.
•
Turn off the power to the
MicroSmart
before starting installation, removal, wiring, maintenance,
and inspection of the
MicroSmart
. Failure to turn power off may cause electrical shocks or fire
hazard.
•
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.
•
Special expertise is required to install, wire, program, and operate the
MicroSmart
. People with-
out such expertise must not use the
MicroSmart
.
Warning
Caution
•
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 malfunction.
•
Do not touch the connector pins with hand, otherwise electrostatic discharge may damage the
internal elements.
Installation Location
The
MicroSmart
must be installed correctly for optimum perfor-
mance.
The
MicroSmart
is designed for installation in a cabinet. Do not
install the
MicroSmart
outside a cabinet.
The environment for using the
MicroSmart
is “Pollution degree 2.”
Use the
MicroSmart
in environments of pollution degree 2 (accord-
ing to IEC 60664-1).
Make sure that the operating temperature does not drop below 0°C
or exceed 55°C. If the temperature does exceed 55°C, use a fan or
cooler.
Mount the
MicroSmart
on a vertical plane as shown at right.
To eliminate excessive temperature build-up, provide ample venti-
lation. Do not install the
MicroSmart
near, and especially above,
any device which generates considerable heat, such as a heater,
transformer, or large-capacity resistor. The relative humidity should
be above 30% and below 95%.
The
MicroSmart
should not be exposed to excessive dust, dirt, salt,
direct sunlight, vibrations, or shocks. Do not use the
MicroSmart
in
an area where corrosive chemicals or flammable gases are present.
The modules should not be exposed to chemical, oil, or water
splashes.
