DANGER
Mortal danger due to internal arc
The switchgear is classified according to IEC 62271‑200, which means that hazardous areas
are specified as indicated on the rating plate (type plate). Uncontrolled access to hazardous
areas can cause life-endangering injury in case of internal arc.
⇨ The switchgear operator must establish the accessibility to the switchgear room in
accordance with the spatial conditions and the equipment installed in there.
⇨ Observe the switchgear design and determine the IAC classification of the switchgear by
means of the data on the rating plate.
WARNING
High speed moving parts
Parts behind covers can automatically move quickly and cause serious injury.
⇨ Do not remove any covers from the switchgear.
⇨ Do not reach into openings.
CAUTION
Switching operations with missing service readiness
Switching without service readiness can cause injury due to an internal arc.
⇨ Check service readiness of the switchgear before performing any switching operation.
The pointer of the ready-for-service indicator must be in the green area.
⇨ If the pointer of the ready-for-service indicator is in the red area:
⇨ Do
not
operate the switchgear.
⇨ Contact the Siemens Service Hotline.
CAUTION
Operating lever slipping off or turning back
When the operating lever is inserted in the actuating opening, it can slip off and cause
injury. The tensioning force of the operating spring can turn the operating lever back and
cause injury.
⇨ Insert the operating lever carefully in the actuating opening.
⇨ Hold the operating lever at both handles while switching.
⇨ After switching, remove the operating lever from the actuating opening.
NOTICE
Incorrect operating levers
Using incorrect operating levers can damage or deactivate the safety equipment of the
switchgear.
⇨ Use only the original Siemens operating levers corresponding to the switchgear type.
