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.
