3.5 eNB Power and Grounding
3.5.1 Connect Power Cable
Since the length of cable needed for power varies from site to site, the two ends of the power
adaptor are bare terminal ends. You will need to make the power cable according to the actual
measurements of the installation site and assemble the power plug and power terminal on the two
ends of the power adaptor.
Strip 0.47 in (12 mm) insulating layer with a wire stripper. The power cord length should be kept
below 330 ft (100 m). The connection steps for the power cable are as follows.
1.
Assemble the power plug. The power plug will be installed on the end of the input direction.
Refer to the labels on the power plug for connecting the live wire, neutral wire, and ground
wire to the corresponding terminals separately, and tighten the screws.
2.
Connect the output of the power adaptor to the lightning protection box.
3.
Assemble the power terminal. The power terminal will be installed on the end of the output
direction. Refer to Figure 3-10 to connect the live wire and neutral wire.

4.
Connect the power cable to the PWR interface in the wiring cavity.
5.
The power cable lays along the slot and stretches out of the wiring cavity.
6.
The input of the power adaptor connects to the outlet.
If the outlet is indoors, place the power adaptor indoors.
If the outlet is outdoors, place the power adaptor in a waterproof box.
7.
After the cable connection is complete in the wiring cavity, tighten the screws on the cover to
close the wiring cavity using a Phillips-head screwdriver.
3.5.2 Connect Grounding Cables
Prepare the grounding cable according to the actual measurements and requirements of the
specific installation site. The Nova846 eNB has two grounding screws located on the bottom of the
unit, as shown in Figure 3-11. Follow the steps below the figure to connect the ground cable.
