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/xx4)!
4) Cooling performance adequate also with optional internal braking resistor

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