WARNING: WARNING: To reduce the risk of electric shock, be sure that the cable grounding kit is properly
installed and connected to a suitable protective earth terminal before connecting the power
source to the rack.
CAUTION: CAUTION: This equipment is designed to permit the connection of the earthed conductor of the DC supply circuit to the
earthing conductor at the equipment. If this connection is made, all the following must be met:
This equipment must be connected directly to the DC supply system earthing electrode conductor or to a bonding
jumper from an earthing terminal bar or bus to which the DC supply system earthing electrode conductor is
connected.
This equipment must be located in the same immediate area (such as adjacent cabinets) as any other equipment that
has a connection between the earthed conductor of the same DC supply circuit and the earthing conductor, and also
the point of earthing of the DC system. The DC system must be earthed elsewhere.
The DC supply source is to be located within the same premises as the equipment.
Switching or disconnecting devices must not be in the earthed circuit conductor between the DC source and the
point of connection of the earthing electrode conductor.
