11-6 Operating Instructions SIMOVERT MASTERDRIVES
The derating of the permissible rated current for installation altitudes of
over 1000 m and at ambient temperatures below 45 °C is calculated as
follows:
Total derating = Derating
altitude
x Derating
ambient temperature
K = K
1
x K
2
It must be borne in mind that total derating must not be greater than 1!
Example: Altitude: 3000 m K
1
= 0.845
Ambient temperature: 35 °C K
2
= 1.25
⇒
Total derating = 0.845 x 1.25 = 1.056 (= 1)
