Power Cables (DC Chassis)
1. Power down the –48Vdc supply.

reliably connected to earth.
Caution
2. Guide the free end of a DC power cable, with about
insulation stripped from the wires, to the terminal block
supplied with the XR900 DC chassis. Clamp the DC leads
(positive, negative, and ground) to the terminal block as

The connection to DC power consists of three #10 AWG
!
wire leads. To avoid grounds or shorts, exercise care
when securing the wires to the terminal block.
