Quick Install Guide 13
1. Remove the transparent protective terminal cover.
2. Strip the supply cable wires to expose 7.5mm (0.31 in.) of bare
conductor. Terminate with a nylon insulated solderless ring tongue
terminal, JST FN5.5-5 or equivalent, using a crimp tool.
3. Connect the ground wire to the ground terminal. Use the diagram on
the rear panel of the switch to identify terminals. Tighten the terminal
to between 2.4 and 4.0 Nm (21.3 and 35.4 lbf in).
Warning Check that the PSU terminals are wired to the correct polarity. A PSU
will be damaged if incorrectly connected.
4. Connect the positive feed to the + (positive) terminal and the negative
feed to the - (negative) terminal. Tighten the terminals to between 2.4
and 4.0 Nm (21.3 and 35.4 lbf in).
5. Ensure there are no exposed cable strands.
Warning Ensure the transparent plastic terminal cover is replaced.
6. The cover must be replaced before continuing.
7. Secure the supply cable to the rack framework or a similar object to
ensure that connections are isolated from any force applied to the
cable.
8. Ensure the circuit breaker for the supply circuit and the Run/Standby
switch on the PSU are in the Off position. Use a small diameter pin to
operate the Run/Standby switch. When the Run/Standby switch is
pushed out, it is Off.
9. Connect the supply cable wires to the circuit breaker.
10. Push the Run/Standby switch in to the On position using a small
diameter pin.
Confirm that the switch is receiving power
Check that at least one of the PSU LEDs on the switch’s front panel is lit green.
If the LEDs fail to light, refer to the AT-9900 Series Hardware Reference for
troubleshooting information.
