Figure 5-61 shows the details of the load configuration circuit.
Note that each power node is shared by two channels. (See

Each channel connects to the power bus via a Form C SPDT
(single-pole, double-throw) relay. This relay has a NO
(normally-open) and a NC (normally-closed) terminal. Each NO
terminal is connected to a pin on
J808–J813, and each NC terminal is connected to a pin on
J802–J807. Each pin on J802–J813 can be connected to any of
the four power busses on J801 via jumper wires
The terminal block jumpering allows convenient pull-up or
pull-down of the various inputs. It also lets you terminate a UUT
load at a different voltage than ground.
The factory default is to provide two jumper combs, one that
ties all the pins on J802–J807 together and one that ties all the
pins on J808–J813 together. The NO pins are also jumpered to
power bus 2, and the NC pins are jumpered to power bus 1. You
