Ensure that you are familiar with the danger notices for Lenovo Storage V series.
Electrical voltage and current from power, telephone, and communication cables are hazardous. To avoid a shock hazard:
This symbol is marked on the frame of the rack.
The PROTECTIVE
EARTHING CONDUCTORS should be terminated at that point. A recognized
or certified closed loop connector (ring terminal) should be used
and secured to the frame with a lock washer using a bolt or stud.
The connector should be properly sized to be suitable for the bolt
or stud, the locking washer, the rating for the conducting wire used,
and the considered rating of the breaker. The intent is to ensure
the frame is electrically bonded to the PROTECTIVE EARTHING CONDUCTORS.
The hole that the bolt or stud goes into where the terminal conductor
and the lock washer contact should be free of any non-conductive material
to allow for metal to metal contact. All PROTECTIVE EARTHING CONDUCTORS
should terminate at this main protective earthing terminal or at points
marked with . (R010)
