2) When designing the drive, it is to be taken into account that the maximum output voltage reduces as a function of the active power.
3) Connection of an ext. braking resistor to devices with int. braking resistor not permitted (model G395-xxx-xxx-xx2)!
4) Cooling performance adequate also with optional internal braking resistor

The coolant temperature can be between +5 °C (+41 °F) and
+40 °C (+104 °F). However, the coolant temperature should
Feed coolant temperature
not be more than 10 °K below the ambient temperature to
prevent condensation on the heat sink.
