3.2
Degree of protection
The degree of protection designation in accordance with EN 60034-5 (IEC 60034-5) is
described using the letters IP and two digits, e.g. IP64.
IP = International Protection
1st digit = protection against the ingress of foreign bodies
2nd digit = protection against water
The validity of DIN 60034-5 refers to water as a medium that can potentially enter, and not
oil. Since machine tools, for example, use oil-containing, creep-capable and/or aggressive
cooling lubricants, protection only against water is not sufficient.
Configure the motor in the environment of creep-capable oils with the appropriate degree of
protection.
