Safety Sa fety Infor mation
Check the electrical connection of the device before operation and ensure that the device is reliably grounded.
When working at a height, be cautious about falling objects.
When operating the device, comply with the local safety regulations. The safety precautions provided in the documents are supplementary. You must comply with the local safety regulations. Power off the device before performing operations on the power supply equipment. High power radio-frequency signals are harmful to human body. Before installing or maintaining an antenna on a steel tower or mast with a large number of transmitter antennas, the operator should coordinate with all parties to ensure that the transmitter antennas are shut down. When handling optical fibers, do not stand cl ose to, or look into the optical fiber outlet with unaided eyes.
When working on batteries, take measures to prevent short ci rcuits in the batteries and electrolyte spill/loss. The electrolyte may erode metal and boards, or even cause rust of the equipment or short circuits in the boards.
When the cabinet is unpacked, it must be powered on in seven days. The maximum duration of the power-off state of the cabinet is 48 hours during maintenance.

Installing the Cabinet and PGND Cables Installing the Cabinet If the cabinet is installed with the power subrack before delivery, you should remove the power subrack from the cabinet and also the power cable between the power subrack and the DCDU-01 and PGND cable for the power subrack before tightening bolts. After the cabinet is installed, install the po wer subrack, related power cable, and related PGND cable. The cabinet door can be removed before the cabinet is installed for easy operations.

Installi ng Cables In this document, the cable color and equipment appearance is for reference only. The actual cables and equipment may differ from what are shown in the figures. Attach labels before routing cables. When cutting the BTS3900 input power cable, reserve an extra length of 300 mm. Add an OT terminal to the cable on si te.
Installing the Input Power Cable Plastic cover plate
The method for installing the power cable for cabinets installed side-by-side or power cable for stacked cabinets is the same as that for installing the power cable for a single cabinet.
When arranging for the power cable on site, do not expose the metal wire.

If main and diversity are not distinguished, the RF signals transmitted from the left RF unit are regarded as the main signals by default, and the RF signals transmitted from the right RF unit are regarded as the diversity signals. If an antenna system serves six sectors, the colors of the rings for sectors 4, 5, and 6 are purple, orange, and green respectively. If the inter-RFU RF signal cables are installed before the cabinet is delivered, only the cables on the ANT_TX/RXA ports need to be installed. The methods for routing RF jumpers in a single cabinet and in cabinets installed side-by-side are the same. The cover plate of the upper cabinet must be removed before the RF jumpers are installed in stacked cabinets.

2. Wrap three layers of ins ulati ng tapes.
The waterproof tape should be wrapped for an extra length of 20 mm away from the connectors at both ends. The tapes should be wrapped around the connector from the lower part to the upper part. When wrapped for another layer, the tapes may not be cut. When wrapping the waterproof tape, ensure that the upper layer of the tape covers at least 50% of the lower layer. The insulating tape should be wrapped for an extra length of 20 mm away from the waterproof tapes at both ends.
