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.
