4.

Pay attention to the safety tags or warnings attached to the equipment. Do not cover the tags and warnings or even remove them off the equipment under any conditions.

5.

Never install the equipment in a place where there is a risk of liquid or objects falling inside the equipment as short circuit may occur and damage the equipment!

6.

Do not stack heavy objects on top of the cabinet so as prevent damage to the equipment!



8


7.

While drilling, operators should take measures to prevent dust from entering people's respiratory tracks or eyes.

8.

Wear safety helmets on site as objects falling from heights might cause severe physical injuries or even deaths. It is forbidden to stand right under the heavy objects!

9.

The electrical devices should be installed or reconstructed by experienced electricians as any faults in electrical installation may cause fires, electric shock, or explosions.

10. People working at heights should be qualified with related certificates. They should conform to the local laws, regulations, and instruction guides. 11. Never work at heights (e.g. on the tower) in severe weather (e.g. in rains or fogs). 12. When working at or around the transmit antenna, ensure that the antenna is in a disconnected state or its power is reduced to a safety level. 13. When installing batteries, pay attention that: (1) The batteries should be of the same type. Old and new batteries must not be used together; (2) The battery packs must not be short-circuited in any way during the operation; (3) Before the cables are connected to the battery, power off the battery to prevent any possible physical injuries. 14. Insulated tools should be used for electrical connection. Connection terminals and exposed parts should be fully insulated. (1) The cross-sectional area of cables should match the load; (2) When the colors of the power cables indicated in this document differ from those in the local area, adopt the cables of different colors in that local area. Remember to use the black heat shrinkable sleeve or insulation tapes for a black power cable so as to prevent any confusion. 15. When operating with the optical cables, ensure that: (1) The temperature is above -20 ℃; Protective measures are taken for your eyes so as to prevent them from direct sight of the optical ports.

2.

Attach labels to the tail of the optical fibers so as to identify different sectors.

The bending radius of the optical cable should be 20 times the length of its diameter. In most cases, greater than 40 mm is recommended. At the BBU side, the optical fibers inside the cabinet should be protected using coil tubes.

Note: Connect the ends of the optical fibers of sectors 1, 2 and 3 to TX0 RX0, TX1 RX1, and TX2 RX2 ports on the BPL board in the BBU. Connect the other ends of the optical fibers to the OPT1 ports of the corresponding RRU.

The cable holes without cable in the waterproofing module should be sealed with the waterproofing rubber!
