2.2.2.2 Install the DC Power Cabling (Optional)

If the system is equipped with the 1 RU Distribution Shelf, follow the instructions below. For systems without the 1 RU Distribution Shelf, skip this procedure and go to the “2.2.3 Install the Ground Cable” procedure on page 2-9.

Step 1 Locate the four 6AWG (16mm²) power cables provided at the rear of the system shelf (on top of the system shelf in preinstalled systems). These are terminated with Anderson Powerpole™ Connectors (to install these connectors, remove the heat shrink from the ends of the connector).

Step 2 Connect to the appropriate connection points on the 1RU Distribution Shelf labeled load (-48V) and return (RETURN) (Figure 2-8).

Note Anderson Powerpole™ Connectors are keyed and can only be inserted one way. If the connector does not insert easily into the mount, make certain that the connector is being inserted with the key side up.
