3.1.2 Protection specifications and operating supply
The standard drive unit has used the protection method which fitted IP20 (open type) of the IEC standard.
Oil mist environment also prepares the drive unit (IP54 of the IEC standard (encapsulated type)) of the protection
specification which can be used.
The IEC IP symbols refer only to the degree of protection between the solid and the fluids, and don't indicated
that any special protection has been constructed for the prevention against oil and water.
【Information】
・ The IEC IP20
It indicates the protective structure that prevents an iron ball 12

mm diameter, which is being pressed with
the power of 3.1 kg±10%, from going through the opening in the outer sheath of the supplied equipment.
・ The IEC IP54
The IEC IP54 standard refers to protection structure designed to prevent any harmful effects by fresh water
scattering vertically onto the testing equipment in a radius of 180 degrees from a distance of 300 to 500 mm, with
10 ± 0.5 liters of water every minute, at a water pressure of 80 to 100kPa , covering the entire area of the robot
with the exception of the installation section at 1 ㎡ per minute, for a total of 5 minutes or more.
Refer to the section Page 104, "6.2 Working environment"for details on the working environment.
If the robot is used in an oil mist environment, use the optional controller protection box
(CR1D-MB) to protect the controller from the oil mist environment(DU1A-700 drive unit
only).
