2.2 Conditions of Use
Maximum installation elevation and ambient temperature
The power data of the motor apply to
•
an ambient temperature range of 0º to +40º C
•
and an installation elevation of 0 to 1000 meters above sea level.
If the motor is to be used above this range, then the "load factors" must
be taken into consideration. This derates the output data.
⇒
In cases like this, check whether the output data still suffice for your
application. To determine the load factors, see Fig. 2-2. Values higher
than those depicted are not permitted!
WARNING
Motor damage and forfeiture of guarantee!
Motors used outside of the specified conditions could be
damaged. Such use also results in forfeiture of gua-
rantee.
⇒
Please therefore note the following instructions!
Fig. 2-2: Load factors as dependent on ambient temperature and installation ele-
vation
If either ambient temperature or installation elevation exceed nominal
ratings then:
⇒
Multiply the continuous standstill torque listed in the selection data
with the determined load factor .
⇒
Make sure that the derated torque is not exceeded by your application.
If both ambient temperature and installation elevation exceed nominal
ratings then:
⇒
Multiply the determined load factors f
T
and f
H
.
⇒
Multiple the determined value by the continuous standstill torque of the
motor indicated in the selection data.
⇒
Make sure that the derated torque is not exceeded by your application.
