3.2 Power Supply and Consumption
Figure 13 shows the typical power consumption of the system. If other AC/DC power supplies than the
standard specified ones are used, it is recommended to evaluate them under demanding operating situations
like fast braking from maximum speed and during power on and take-off of the impeller.

3.3 Temperature Monitoring
To avoid overheating of the system, the controller and motor temperatures are monitored. If the controller
temperature exceeds 70°C (158°F) or the motor temperature 90°C (194°F) for a duration of more than 10
minutes, the system goes into an error state and the pump stops. At 80°C (176 F) controller temperature or
100°C (212°F) motor temperature, the system stops immediately.
