The cables are connected to the bushings with IEC type
reinforced connection connectors (screwable).
Never touch live connectors, not even screened
connectors. Screening does not constitute protection
against direct contact.
When the equipment is in service and a back-up cubicle
is left with voltage in the top busbar and without
cables in the bottom bushings, insulating plugs must
be placed on the bushings or the disconnector must
be placed in earthing position, and locked in this
position with a padlock.
