Supply networks
This product is designed for fixed connection to TN networks (TN-C, TN-C-S or TN-
S). Please note that the line-earth voltage may not exceed 300VAC.
When grounding the neutral conductor, mains
voltages of up to 480VAC are permitted.
When grounding an external conductor (delta
mains, two-phase mains), mains voltages (external
conductor voltages) of up to 240VAC are
permitted.
Devices which are to be connected to an IT network must be provided with a
separating transformer. Then the devices are operated locally as in a TN network.
The secondary sided center of the separating transformer must be grounded and
connected to the PE connector of the device.
