Suitable conductor material: use copper conductors only
Power supply connections through the input connector: 8 AWG (between the server and the source). There are three conductors:
-48V or -60V (negative terminal)
Chassis ground connection
-48V or -60V Return (positive terminal)
System ground conductor: 8 AWG (to be connected to the chassis)
Cable insulation rating: Minimum of 75?C (167?F), low smoke fume (LSF), flame retardant
Provide the mating connector, Wago Part Number 51204745, for proper connection to the DC connectors supplied with the server.
This connector requires a 4mm flat-blade screwdriver to insert wires into the connector body.
Branch circuit cable insulation color: Per applicable National Electrical Codes
Grounding cable insulation color: Green/Yellow
DC power source must meet TNV-2 requirements as defined by UL 60950-1 and IEC 60950-1
Note - Depending on the DC power source, the -48V or -60V (negative terminal) might be marked with a minus (-) symbol, and the -48V or -60V Return (positive terminal) might be marked with a positive (+) symbol.
When attaching DC cables, keep the following caution in mind:
Caution - You must restrict the connection of the server to the DC power source to minimize the possibility that transient energy will appear on the main input to the equipment. The DC battery power source must be in the same premises as the server. The server cannot be in one building with the power source in another building.
