Installation altitude: ≤ 1000 m
Air with normal oxygen content, usually 21 % (V/V)
If the environmental requirements are different from the details listed here, then the values
on the rating plate will apply.
Machines intended for use in Zone 1 (type of protection Flameproof Enclosure "d" or
Increased Safety "e") or in Zone 2 (type of protection "n") are designed with IP 55 degree of
protection.
Machines intended for use in Zone 21 have IP 65 degree of protection. Machines intended
for use in Zone 22 have IP 55 degree of protection and can be used in dusty environments
such as grinders, silos, animal feed plants, and malthouses, as well as in certain areas of the
chemical industry.

Optional built-on and built-in accessories

In addition to the current-dependent overload protective device located in the connecting
leads, we recommend that you use temperature sensors embedded in the stator winding in
order to monitor the temperature and protect the stator winding from overheating.
Machines whose winding is exposed to the danger of condensation due to the climate, e.g.
machines at a standstill in a damp environment or machines which are exposed to large
temperature fluctuations, can be equipped with an anti-condensation heater.
As an option, the machines can be fitted with additional built-on accessories on the
ventilation side (e.g. brake, rotary pulse encoder).
