(3) Precautions for braking resistor

CAUTION

• Install the braking resistor on a noncombustible object, such as metal.

Failure to do so may cause ﬁ re.

• Do not place the braking resistor close to a combustible object. Doing so

may cause ﬁ re.

• Do not install the braking resistor in an ambient environment where the

temperature is high, the humidity is high, or dew condensation occurs

easily or a place where dust, corrosive gas, explosive gas, ﬂ ammable gas,

coolant mist, or salt damage exists. Always install the braking resistor in a

well-ventilated indoor place where it is not exposed to the direct sunlight.

Failure to do so may cause ﬁ re.

• The braking resistor generates heat by itself. So, install the braking resistor

far away from the robot driver or cables.

Additionally, carefully check the ventilation and dimensions so that the

ambient temperature of the robot driver does not exceed its operating

range. Failure to do so may cause ﬁ re.

• When installing the braking resistor in a place where it may be in contact

with a human body, cover it with breathable protective metal ﬁ xtures so

that it is not directly in contact with a human body. Failure to do so may

cause personal injury.
