Environmental conditions during operation
5.5.1
Ambient temperature
The temperature range of -20 °C to 40 °C must be ensured unless specified otherwise
on the nameplate. Motors intended for use in higher or lower ambient temperatures have
the appropriate designation on the nameplate.
5.5.2
Installation altitude
The maximum installation altitude of 1000 m above sea level must not be exceeded.
5.5.3
Hazardous radiation
Motors must not be subjected to hazardous radiation (such as ionizing radiation). Con-
tact SEW-EURODRIVE if necessary.
5.5.4
Hazardous gases, vapors and dusts
If used according to their designated use, explosion-proof motors are incapable of ignit-
ing explosive gases, vapors or dusts. However, explosion-proof motors may not be sub-
jected to gases, vapors or dusts that endanger operational safety, for example through
• Corrosion
• Damage to the protective coating
• Damage to the sealing material
etc.
