Connect Gps Antenna Cable; Connect Rf Cable(S) - Baicells Nova436Q Installation Manual

Nova436Q Outdoor 4x1W Two-Carrier TDD eNodeB Installation Guide
Bending radius of power cable and grounding cable: > triple the diameter of the cable.

The minimum bend radius of the optical fiber is 20 times the diameter of the optical fiber.

Bind the cables according to the type of cable; intertwining and crossing are forbidden.

An identification label should be attached after the cable is laid.

Optical fiber cable requirements:
• Avoid circling and twisting of cables while laying the cable.
• Avoid binding or kinking of cables on a turn.
• Avoid pulling or weighing down the optical fiber cable.
• The redundant optical fiber must wind around the dedicated device.
Grounding cable requirements:
• The grounding cable must connect to the grounding point.
• The grounding cable must be separated from the signal cables to avoid signal interference.

3.4.2 Connect GPS Antenna Cable

WARNING: Ensure the antenna is connected before powering up the eNB. The wireless signal
transmission power can cause bodily injury and damage to the eNB and RF power amplifier
devices.
1. Insert the GPS jumper into a cold shrink tube.
2. Connect one end of the GPS jumper to the GPS antenna.
3. Push the cold shrink tube to the top joint and pull out the strip.
4. Connect the other end of the GPS jumper to the GPS interface on the eNB, which also needs
weatherproof protection.
NOTE: The top of the GPS antenna should avoid the front of the directional antenna as much as
possible.

3.4.3 Connect RF Cable(s)

WARNING: Ensure the antenna is connected before powering up the eNB. The wireless signal
transmission power can cause bodily injury and damage to the eNB and RF power amplifier
devices.
1. Open the dust caps of the ANT0, ANT1, ANT2, and ANT3 interfaces.
2. Insert the RF cables into cold shrink tubes.
3. Connect RF cables to the ANT0, ANT1, ANT2, and ANT3 interfaces on the eNB, and tighten them
with a wrench to 12–15 in-lb or 1.4–1.7 NM torque.
NOTE: Antenna ports ANT0 and ANT1 connect to the primary cell (Pcell), or Cell 1. Antenna ports
ANT2 and ANT3 connect to the secondary cell (Scell), or Cell 2.
4. Push the cold shrink tube to the top joint and pull out the strip.
5. Connect the other end of the RF cables to the external antennas, which also need weatherproof
protection.
