Devices
2200 A - 3000 A
See Chapter "Dimension drawings (Page 80)" for how the protective conductor can be connected.
Note:
If the device is stored for a longer period of time, a layer of corrosion can form on the bare metal surfaces of the housing.
Before connecting the protective conductor, this must be removed from the connection points.
The devices are designed for a permanent line supply connection in accordance with
EN 61800-5-1.
The conductor cross-sections (also for the protective conductor) must be determined in
accordance with the applicable regulations that apply in each case – e.g. EN 60204-1.
