3.2.1 Test ange for thermal determinations
The rated power (rated torque) applies for continuous operation (duty type S1) at ambi-
ent temperature of 50°C and site altitude of up to 1,000 m above sea level. It is deter-
minedbyusingdenedaluminiumtestanges(seetableopposite).
Material number Dimension of the test ange
7606910-40xx
410 x 396 x 23

heat. This requires a reduction of the rated motor torque.
3.2.2 Coolant temperature at different site altitudes
At higher temperatures or site altitudes, the load capability of the motors is reduced (see
the following table).

CAUTION
High surface temperatures !
Fire and burn protection
► The motors can reach a surface temperature of more than 100°C.
► No temperature-sensitive parts shall be connected or fastened. If
necessary, protective measures must be taken against touching.
