13.6 Precautions

(1) The controller protective box is a dust-proof, splash-proof structure equivalent to

JIS IP53.

The controller protective box is not explosion-proof and must not be installed in

the following environments and locations to ensure safety:

• in an environment full of combustible gas, flammable liquid, etc;

• in an environment full of acid or alkali corrosive gas;

• in a location close to electric noise sources, such as large inverters, high-

output high-frequency generators, large conductors and welders;

• in a location where the controller protective box will not be used outside the

ambient temperature range from 0°C to 40°C;

• in a location where the controller protective box will be exposed to rain or dew;

• in an environment where the controller protective box will be exposed directly

to water, oil or chips;

• in an environment where fine chips will be produced from cutting, etc;

• in an environment using oil not specified in this manual.

(YUSHIRON OIL No. 4 is specified.)

(2) Seal the mounting face and screws of the controller protective box when using it

in an environment full of oil mist. Otherwise oil mist may accumulate on the fin,

resulting in a collection of oil. Periodically clean the controller protective box.

(3) If oil mist, etc. collects in the controller protective box, remove the drain hole

screw and drain off the oil.

(4) The controller protective box is not equipped with a power switch. Use external

means to turn the controller on or off.

(5) The controller protective box must be installed horizontally. Vertical installation

will cause accidents.
