For +24 VDC installations
Follow these steps to wire and connect +24 VDC power feeds (see Figure 24):
Step 1. For CBN installations only, ensure that the negative terminal on the DC power source
is connected to ground.
Step 2. Make the battery return ground connection(s) (Figure 24, key item 5).
Attach the blue lead (-VDC) on the power harness to the negative terminal on the
power source.
Step 3. Make the battery connection(s) to the disconnect device (Figure 24, key item 1).
Attach the black lead (+VDC) on the power harness to the disconnect device.
Attach the other side of the disconnect device to the positive terminal of the power
source.
Step 4. For redundant supply configurations, repeat Steps 1 and 2 for the other power
harness.
Step 5. Check that the DC supply wiring is correct.
Step 6. Attach the connector on the power harness to the D-Sub 2W2 connector on the
7705 SAR-8.
Step 7. Install the other 7705 SAR-8 components. See Installing the Components.
