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 ： Protection specifications and applicable fields
Type
RV-3S
RV-3SJ
Note1)
RV-3S-SM
RV-3SJ-SM
Note1) The "-SM" specification (specification with the controller protection box) comes with the controller
protection box (CR1B-MB) as standard.
CAUTION
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 ： Tested cutting oil for oil mist specifications

【Information】
・ The IEC IP20
It indicates the protective structure that prevents an iron ball 12
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.
・ 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
device surface area for a total of three minutes.
