3. Installing the Controller
WARNING
● To prevent electric shock, the source of power to the controller must be turned off
when mounting the controller on to a panel.
● Since the controller is not of explosion-proof type, do not use this controller in
combustible or explosive gas atmospheres.
CAUTION
To install the controller, select a location where:
1. No-one may accidentally touch the terminals;
2. Mechanical vibrations are minimal;
3. Corrosive gas is minimal;
4. The temperature can be maintained at about 23°C
with minimal fluctuation;
5. There is no direct heat radiation;
6. There are no resulting magnetic disturbances;
7. The terminal board (reference junction
compensation element, etc.) is protected from wind;
8. There is no splashing of water; and
9. T here are no flammable materials.
Never place the controller directly on flammable items.
If the controller has to be installed close to flammable items or
equipment, be sure to enclose the controller in shielding panels
positioned at least 150mm away from each side. These panels
should be made of either 1.43mm thick metal-plated steel plates
or 1.6mm thick uncoated steel plates.
