below.

Only one 20A output TB1 is shown for clarity. Note that both 24V supplies on TB1 are connected to
feeder 24V-1. TB2 is also wired to 24V-1. TB3 and TB-4 are powered from 24V-2. This means that if a
separated dual redundant supply is required, each output must be wired to one supply on 24V-1 and
one supply on 24V-2. Figure 3 shows a simplified diagram of the connections.
