III. Connect power cords to the power distribution box
Caution:
The power distribution box takes AC high voltage. Do not operate it before breaking its
power.
1) Use three cables to connect the client power distribution box to the terminal block
of the cabinet power distribution box. You are recommended to use the cables
with 16 mm
cable specifications in different countries). Connect the power cords according to
the following relations:
Live wire L in the client power distribution box — Live wire L in the cabinet power
distribution box
Neutral wire N in the client power distribution box — Neutral wire N in the cabinet
power distribution box
Earth wire G in the client power distribution box — Earth wire PE in the cabinet
power distribution box
2) Use 3.5 m (11.5 ft) long cables to connect the cabinet power distribution box to the
system power supply and PoE power supply. The three wires of each cable should
be respectively connected to the ports L, N and PE of the power distribution box.
Make sure the protection tubes are used and no wire tailpiece is exposed during
the connection. You should connect power cord 1 to L1, N1 and PE1, power cord 2
to L2, N2 and PE2, and so on. The number of power cords depends on the cabinet
configuration. Note that you should connect the brown wire to L (live wire), the blue
wire to N (neutral wire), and yellow-green wire to PE (earth wire).
3) After finishing the connection of the cables, bind these cables in order with cable
strap, wire them along the right side of the cabinet down, and connect them to the
input ports of the system power supply and PoE power supply. You should make
sure the cables are not loose.
IV. Installing the power distribution box
You should install the power distribution box on the top of the back of the N68 cabinet.
You can adjust the location of the box in a little range.
