OPENNET CONTROLLER USER’S MANUAL 3-1
3: INSTALLATION AND WIRING
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.
