1.2 How to Install

NOTE

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) temperature can be maintained at about 23°C

and the fluctuation is minimal,

(5) no direct radiant heat is present,

(6) no magnetic disturbances are caused,

(7) no wind blows against the terminal board (reference junction compensation element),

(8) no water is splashed,

(9) no flammable materials are around,

Never place the controller directly on flammable items or equipment.

If the controller has to be installed close to flammable items or equipment, be sure to

provide shielding panels all around the controller, at least 150mm away from every side;

the panels should be made of either 1.43mm-thick metal-plated steel plates or 1.6mm-thick

uncoated steel plates.

●Installation Position

Install the controller at an angle within 30°from horizontal with the front panel facing up-

ward. Do not install it facing downward. The position of right and left sides should be hori-

zontal.
