2.2.5 Protection specifications and working environment
(1) Types of protection specifications
The robot arm has protection specifications that comply with the IEC Standards. The protection specifications
and applicable fields are shown in
Table 2-2
.
Even oil mist environment can be used in addition to the general environment.
Table 2-2 ： Protection specifications and applicable fields
The IEC IP symbols define the degree of protection against solids and fluids, and do not indicate a protective
structure against the entry of oil or water.
The evaluation regarding oil mist specifications has been confirmed with Mitsubishi's standard testing methods
using the cutting oils shown in
Table 2-3
Table 2-3 ： Tested cutting oil for oil mist specifications
【Information】
・ 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.
・ The IEC IP65
Protection against water infiltration as specified in IP65 indicates a protective structure that is not harmfully
affected when 12.5 ± 5% liters of water is supplied from a test device at a position approx. 3m away in various
directions and a water pressure of 30kPa at the nozzle section. The water is filled one minute per 1m
2
of test
device surface area for a total of three minutes.
(2) About the use with the bad environment
This robot has protection methods that conform to IEC'sIP54 (for J1 to J3 axis) and IP65 (for J4 to J6 axis) stan

dards (splashproof type). Recommended usage conditions.
1) The robot is designed for use in combination with machining device.
2) Please examine cutting oil referring to
Table 2-3
used by a standard examination of our company.
3) Take measures so that the robot will not be exposed to water, oil and/or chips for a long period of time.
4) Protection performance can be improved by pressurizing the inside of the robot arm. Since the joint (AIR
PURGE) of phi 8 is prepared at the rear of the base section, please supply the dry air for pressurization from
The specification of the dry air for pressurization is shown in
Table 2-4
.
