3.2.1 DC Mains Grounding Connections

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
conditions 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 in 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 not 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.
3.2.1.1 Disconnect Device – Permanently Connected
A readily accessible disconnect device (circuit breaker or switch) must be incorporated in the building installation
wiring.

3.2.1.2 Multiple Power Source

This product has multiple power sources. If service requires the removal of a power source, disconnect all inputs
(AC and DC powers) to remove power completely to the equipment before servicing.

3.2.1.3 Connection to Primary Power

For supply connections, use wires suitable for at least 75 °C.
