For three-phase power: Using plastic ties, attach the PDU connection tag to
the main AC power cable connected to zone A and B. Place the label close to

Ground the cabinet
Equipment correctly installed within the cabinet is grounded through the AC power
cables and connectors. In general, supplemental grounding is not required.
If your site requires external grounding (for example, to a common grounding network
beneath the site floor), you can use the grounding lugs provided on each of the
cabinet’s bottom supports.
