The RMU20 is designed to operate in an environment whose degree of pollution is 2.
When installing it in the robot controller, use a hermetically sealed structure for the
IMPORTANT
controller, and take measures to make it dust-proof and water-proof.
The degree of pollution of 2 is defined as follows.
"Environments in which electrically conductive dust and dirt are not normally generated, but in which electrical
conduction may be temporarily caused by the build-up of dust and dirt; approximate environments inside a
control panel equivalent to IP54 in the control rooms or on the floors of average factories."
