Introduction
This chapter describes the methods and precautions for installing and wiring
OpenNet Controller
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.
Installation Location
The
OpenNet Controller
must be installed correctly for optimum performance.
The environment for using the
OpenNet Controller
is “Pollution degree 2.” Use the
OpenNet Controller
in environments of
pollution degree 2 (according 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
OpenNet Controller
on a vertical plane.
To eliminate excessive temperature build-up, provide ample venti-
lation. Do not install the
OpenNet Controller
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
OpenNet Controller
should not be exposed to excessive dust,
dirt, salt, direct sunlight, vibrations, or shocks. Do not use the
OpenNet Controller
in an area where corrosive chemicals or flam-
mable gases are present. The modules should not be exposed to
chemical, oil, or water splashes.
•
Turn power off to the
OpenNet Controller
before starting installation, removal, wiring, mainte-
nance, and inspection of the
OpenNet Controller
. Failure to turn power off may cause electrical
shocks or fire hazard.
•
Emergency stop and interlocking circuits must be configured outside the
OpenNet Controller
. If
such a circuit is configured inside the
OpenNet Controller
, failure of the
OpenNet Controller
may
cause disorder of the control system, damage, or accidents.
•
Special expertise is required to install, wire, program, and operate the
OpenNet Controller
. People
without such expertise must not use the
OpenNet Controller
.
Warning
Caution
•
Prevent metal fragments and pieces of wire from dropping inside the
OpenNet Controller
hous-
ing. Put a cover on the
OpenNet Controller
modules during installation and wiring. Ingress of
such fragments and chips may cause fire hazard, damage, or malfunction.
