Removable Power Supply and Fan

Applying Power to the Power Supply Unit

For an AC power supply unit
To apply power to the PSU, plug the AC power cord that is provided into the
power inlet on the faceplate of the PSU. Then connect the power cord to the
main power supply.
For a DC power supply unit
Only trained and qualified personnel should connect a DC power supply.
For centralised DC power connection, the switch should be installed in
restricted access areas only (such as dedicated equipment rooms or
equipment closets) in accordance with Articles 110-16, 110-17, and 110-18 of
the National Electrical Code, ANSI/NAPA 70.
Warning Ensure that the power cable is not live before starting.
1.
Remove the transparent protective terminal cover.
2.
Strip the supply cable wires to expose 7.5mm (0.31 in.) of bare conductor.
Terminate the wire 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).
Caution Check that the PSU terminals are wired to the correct polarity.
You will damage the PSU if you incorrectly connect it.
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).
Note that the DC return input terminal must be connected as Isolated DC
return (DC-I).
5.
Ensure there are no exposed cable strands.
6.
Replace the cover. You must replace the transparent plastic terminal cover
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.
