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 44, "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.
DANGER
High voltage! Danger!
➭ Isolate.
➭ Secure against reclosing.
➭ Verify safe isolation from supply.
➭ Earth and short-circuit.
➭ Cover or barrier adjacent live parts.
DANGER
During operation of electrical equipment and switchgear, parts of this equipment are under
dangerous electrical voltage. Mechanical components may move quickly, even remotely
controlled.
➭ Do not remove covers.
➭ Do not reach into openings.
DANGER
Switching without service readiness can cause serious injury and property damage.
➭ Check service readiness of the switchgear before performing any switching operation.
➭ If the switchgear is not ready for service (pointer in the red area), do not operate the
switchgear, but contact the Siemens Service Hotline.
ATTENTION
Earthing a live incoming cable will result in a short circuit and trip an upstream circuit-breaker.
➭ Verify safe isolation from supply of the feeder before earthing.
