Protective Earth Terminals (PET) are located on the bottom frame of the rack enclosure and are marked to make them easier to locate. Enclosure accessory parts contain or are provided with bonding points for connection to the frame / PET. Bonding and grounding provides an electrically conductive path between the rack, accessory and an earth ground.
