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!
Residual current Local regulations and national guidelines may mean that a residual current cir-
circuit breaker cuit breaker is required when connecting a device to the public grid.
The residual current circuit breaker recommended for the device by the manu-
facturer can be found in the technical data.
