Attaching the ground cable assembly
The PDU /rack combination is a safety Class 1 product and has a
protective earthing (grounding terminal).
The PDU ground strap must be attached to the PDU and rack column
with the supplied hardware. Failure to do so can result in a sever hazard
and/or personal injury in the event of equipment failure or product
misuse.
Additionally, there must be an uninterruptible safety earth ground from
the main power source to the product’s internal wiring terminals, power
cord, or supplied cord set. Whenever it is likely that the protection has
been impaired, disconnect the power cord until the ground has been
restored.
Protect from Shock Hazards. As the number of instruments that connect
to a PDU increases, the magnitude of leakage current also increases. The
magnitude of the leakage current depends on the characteristics of each
instrument. To avoid electric shock, the PDU must connect to the
premise electrical ground system. The PDU earth ground connection
must not be interrupted in any way. Failure to provide an earth
connection can result in injury to the user and damage to the connected
instruments. To assure proper grounding, a qualified electrician should
be consulted.
