7 Installation
In the instructions given in the following sections it is assumed that a new switchgear is being
installed which has not yet been connected to the mains, and is not live.
7.1 Safety instructions
For extending or replacing parts of an existing switchgear, observe the Five Safety Rules:
DANGER
Live parts
Touching live parts leads to a life-endangering electric shock. Observe the Five Safety Rules:
⇨ Isolate.
⇨ Secure against reclosing.
⇨ Verify safe isolation from supply.
⇨ Earth and short-circuit.
⇨ Cover or barrier adjacent live parts
CAUTION
Sharp-edged sheets
If covers have to be removed from the switchgear, sharp-edged sheets inside the switchgear
can cause cuts. Sharp-edged sheets inside the switchgear can damage cables.
⇨ Wear personal protective equipment (e.g. cut-resistant gloves and arm sleeves).
⇨ When working inside the switchgear, it must be observed that cables do not touch any
sharp-edged sheets. Cover sharp-edged spots, if required.
NOTICE
Sheet-metal work at the switching-device vessel
Sheet-metal work at the switchgear can cause damages to the switching-device vessel.
⇨ Do not drill into the switching-device vessel.
⇨ Remove metal cuttings, cement dust or liquids on the switching-device vessel in order to
avoid rust layers.
