-48Vdc Power connections
The -48Vdc power is supplied from a -48Vdc source and connected to a single pair of
19AWG wires on the stub end of the power cable. This cable is terminated inside the
enclosure on a Tyco connector, as shown in Figure C-9.
Figure C-9.
-48Vdc stub-ended power cable
The -48Vdc power does not pass through the protection blocks. A Tyco connector on
a power supply cable connects directly to the stub-ended power cable within the
enclosure and provides the ring connectors that connect directly to the -48Vdc power
supply of the Stinger Compact Remote unit. The -48Vdc power supply cable is shown
in Figure C-10.
