Grid Connection
Devices with a high output can influence the energy quality of the grid due to
their current consumption.
This may affect a number of device types in terms of:

See technical data
In this case, the operator or the person using the device should check whether or
not the device is allowed to be connected, where appropriate through discussion
with the power supply company.
IMPORTANT! Ensure secure grounding of the grid connection!
