8. Torque the captive screws (above the wires) to 8.5 in-lb (± 0.5 in-lb).
9. Complete the power connection:
AC Power Connection

Connect the other end of the line wire (the one connected to L) to the line terminal on the AC-power source, and
connect the other end of the neutral wire (the one connected to N) to the neutral terminal on the AC power source.
DC Power Connection

Connect the other end of the positive wire (the one connected to "+") to the positive terminal on the DC-power
source, and connect the other end of the negative wire (the one connected to "–") to the negative terminal on the
DC power source.
Note: Ensure that you cannot see any wire lead. Only wire with insulation should extend from the terminal screw.
If you have two power supplies, repeat steps 1 through 10.
10. Close the power-input terminal cover.
11. Use a ratcheting torque screwdriver to torque the screw to 7 in-lb (± 1 in-lb).
12. Turn on the power at the AC or DC circuit.
13. Verify that the PSU1 or PSU2 LED on the switch and PSU OK LED on the power-supply module are green.
See the switch software guide for information on how to configure the power supply settings.
