System types
There are three basic types of the current supply systems regarding the grounding, which con-
form with DIN VDE0100 part 300 and IEC 60364:
m
The TN system has a directly grounded point (system grounding). The cabinet of the electrical
installation is connected via the protective conductors and PE conductors with this point.
m
The TT system has a directly grounded point (system grounding). The cabinet of the electrical
installation is connected with grounding electrodes. The grounding electrodes are separated
from system grounding.
m
The IT system has no direct connection between the active conductors (L1, L2, L3, N) and
grounded parts (PE). The cabinet of the electrical installation is grounded. The separation is
reached by using an isolating transformer or an independent current source (generator, bat-
tery).
Supported system types
NOTICE!
The operation of the BUM 60 / BUS 60 is possible at TN / TT systems, only.
