IP (Industrial Protection) code
A cording system to indicate the degrees of protection provided by an enclosure against access to hazardous parts,
ingress of solid foreign objects, ingress of water and to give additional protection in connection with such
protection. Elements of the IP54 level and their meanings are as follows.
IP5x
Represents dust proof to level 5. This level of IP code means that the terminal is protected against solid foreign
objects including dust to penetrate the enclosure.
IPx4
Represents water-splash proof to level 4. No detrimental effect is observed even with exposure to water splashed
from any direction.
“x” represents that a characteristic numeral is not required to be specified.
