WARNING: WARNING: To reduce the risk of electric shock or energy hazards:
This equipment must be installed by trained service personnel.
Connect the equipment to a reliably grounded secondary circuit source. A secondary circuit
has no direct connection to a primary circuit and derives its power from a transformer,
converter, or equivalent isolation device.
The branch circuit overcurrent protection must be rated 27 A.
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 of 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.
