3.3.5.1 Correction values for the output current of the mains inverter BM50XX, BM51XX
Installation
altitude
If the devices BM50XX, BM51XX are operated above an absolute altitude of 1000 m,
then the permitted output current I
permitted
(adjusted output rated current) must be re-
duced against the output rated current (see ZElectrical data BM50XX; BM51XX– as from
page 60) according to the following curve.

Operating
temperature
The devices BM50XX, BM51XX were designed to be operated at an operating tempera-
ture of T
rated
= 40 °C. If the devices are operated at temperatures between 40 °C and
55 °C the permitted output current (I
permitted
) must be reduced:
The coolant temperature complies with the environmental temperature of air-cooled de-
vices, with the water temperature of water-cooled devices and the surface temperature of
the cold plate/mounting panel of devices with cold plate cooling.
The permitted output current I
permitted
(adjusted output rated current) is calculated accord-
ing following formula:
I
rated
= Output rated current at 40 °C and up to 1000 m,,
see ZElectrical data BM50XX; BM51XX– as from page 60.
