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 Z Electrical data BM50XX; BM51XX – as from
page 58) according to the following curve.

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

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
