Electric shock
Always verify safe isolation from supply without any doubt.
In the instructions given in the following sections it is assumed that new switchgear
is being installed, which has not yet been energized with operational high voltage.
If the switchgear is already in operation, operational high voltage could be
applied at the connections / bars in the busbar compartment.
To perform tests or work in the busbar compartment of a switchgear that is
already in operation, follow the directives of the Operating Instructions with
order number 110-0134.9.
Sharp-edged sheets
If the covers have to be removed from the switchgear, sharp-edged sheets inside
switchgear can cause injuries by getting cut. Sharp-edged sheets inside the
switchgear can damage cables.
Put on 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.
