WARNING
Connection to PC is carried out via a standard host/device USB cable. The USB connection is galvanically isolated from
the supply voltage (PELV) and other high-voltage terminals. The USB connection is not galvanically isolated from
protective earth. Use only isolated laptop/PC as connection to the USB connector on the unit or an isolated USB cable/
converter.
Protection and features
•
Temperature monitoring of the heat sink ensures that the active filter trips if the temperature reaches a predefined
level. An overload temperature cannot be reset until the temperature of the heat sink is below the acceptable
values.
•
If a mains phase is missing, the active filter trips.
•
The active filter has a short circuit protection current rate of 100 kA if properly fused
•
Monitoring of the DC-link voltage ensures that the filter trips if the DC-link voltage is too low or too high.
•
The active filter monitors the mains current as well as internal currents to reassure that current levels do not reach
critical levels. If current exceeds a critical level, the filter trips.
