Ambient temperature range 5 °C to 50 °C at a maximum relative humidity of 85 % (without moisture
condensation)
100 % rated current up to max. 40 °C. At higher temperatures the power
must be reduced by 1.5 % per 1 °C.
IP Code IP20
(1) Adjustable via software drivemaster2 : from software version 1.14.100 onwards
(2)
Minimum size of cooling surface: 6 dm² (natural convection)
(3)
Admissible voltage ripple: max. 10 %
(4)
The logic voltage is necessary to maintain the error messages. It is protected by an electronic fuse on the
device.
