However, the factory setting should only be adjusted in
exceptional cases!
Procedure:
- Increase the load until the set current limit responds.
- Adjust potentiometer I

6.2.6 Network monitoring
The mains monitoring module fulfils various functions. It serves to
protect the device against overload and overvoltage with fixed
response values.
The response values can be found in the technical data (section 4.3).

Mains undervoltage monitoring
- The appliance is switched off when the voltage falls below the
switching point. Once the hysteresis voltage has been
exceeded, the device restarts automatically with "soft start".
Mains overvoltage monitoring
- If the maximum permissible mains voltage is exceeded, the
SNT is set to stop for the duration of the overvoltage. After
falling below the hysteresis voltage, the device restarts
automatically with "soft start".
