5.1 General operating conditions
Protection degrees (IP-Code)
The standard IEC 60529 (DIN EN 60529) defines the degrees of protection in different classes.
1. Number: dust protection and
touch guard Definition
0 Non-protected
1 Protected against access to hazardous parts with the back of a hand. Protected against solid
foreign objects of Ø 50 mm
2 Protected against access to hazardous parts with a finger. Protected against solid foreign ob-
jects of Ø 12.5 mm.
3 Protected against access to hazardous parts with a tool. Protected against solid foreign objects
Ø 2.5 mm.
4 Protected against access to hazardous parts with a wire. Protected against solid foreign objects
Ø 1 mm.
5 Protected against access to hazardous parts with a wire. Dust-protected. Intrusion of dust is not
totally prevented, but dust shall not penetrate in a quantity to interfere with satisfactory operation
of the device or to impair safety.
6 Protected against access to hazardous parts with a wire. Dust-tight. No intrusion of dust.
2. Number: water* protection Definition
0 Non-protected
1 Protected against water drops
2 Protected against water drops when enclosure tilted up to 15°.
3 Protected against spraying water. Water sprayed at an angle up to 60° on either side of the ver-
tical shall have no harmful effects.
4 Protected against splashing water. Water splashed against the disclosure from any direction
shall have no harmful effects
5 Protected against water jets
6 Protected against powerful water jets
7 Protected against the effects of temporary immersion in water. Intrusion of water in quantities
causing harmful effects shall not be possible when the enclosure is temporarily immersed in wa-
ter for 30 min. in 1 m depth.
*) These protection classes define only protection against water!
Chemical Resistance
The Resistance relates to the Housing of the Fieldbus/EtherCAT Box and the used metal parts. In the table
below you will find some typical resistance.
Character Resistance
Steam at temperatures >100°C: not resistant
Sodium base liquor
(ph-Value > 12) at room temperature: resistant
> 40°C: not resistant
Acetic acid not resistant
Argon (technical clean) resistant
Key
• resistant: Lifetime several months
• non inherently resistant: Lifetime several weeks
• not resistant: Lifetime several hours resp. early decomposition
