Operation
DANGER
The internal arc classification of the switchgear according to IEC 62271-200 has only been
proved by tests for the switchgear sides with internal arc classification and with closed
high-voltage compartments.
➭ Determine the IAC classification of the switchgear by means of the data on the rating plate
(see page 48, "Rating plates").
➭ Regulations for access to switchgear areas without internal arc classification according to
IEC 62271-200 must be defined by the entrepreneur or the switchgear operator.
