5.3 Ambient conditions during operation
5.3.1 Ambient temperature
The ambient temperature must correspond with the information on the nameplate and
on the order confirmation. If the ambient temperature according to the nameplate
is > 50 °C, it is essential that the cables and cable glands used are suited for tempera-
tures = 90 °C.
5.3.2 Hazardous radiation
Motors must not be exposed to hazardous radiation (such as ionizing radiation). Contact
SEW-EURODRIVE if need be.
5.3.3 Hazardous gases, vapors and dusts
If used according to their designated use, explosion-proof servomotors are incapable of
igniting explosive gases, vapors or dusts. However, explosion-proof motors may not be
subjected to gases, vapors or dusts that endanger operational safety, for example
through
• Corrosion
• Damage to the protective coating
• Damage to the sealing material
etc.
5.3.4 General information on explosion protection
The explosion-proof CMP synchronous servomotors are intended for the following ap-
plication zones.
5.3.5 Degree of protection IP65
SEW-EURODRIVE servomotors in category 3D and 3GD are supplied with at least en-
closure IP65 (forced cooling fan not permitted for ATEX).
5.3.6 Temperature class / surface temperature
The servomotors are designed for temperature class T3. The maximum surface temper-
ature is 150 °C.
