Before installing and operating the CrossFire, read and comply with the following safety instructions:
1. Engineering design: The CrossFire achieves signal amplification of the uplink and downlink through
direct coupling of the 2G, 3G and LTE signals from the base station. The expansion unit accesses WLAN
signals and combines the WLAN signal with the coupled signal for indoor coverage. Normal use of the
system will not damage the base station; however, with the increase of RU during network coverage for
indoor distribution, the uplink output noise level may affect the sensitivity of the base station, which should
be considered during engineering design.
2. Grounding: the shells of the access and expansion units of the device have protective ground
terminals. During installation, connect the ground terminals securely to the protective building ground with
yellow and green conductors or with braided ground wire. The aerial and feeder must be adequately
grounded.
3. Power supply: The power source must be within the required range of the device. The rated voltage
range for the AC power supply system is AC100V
～
240V and the rated frequency range is 50Hz / 60Hz. The
rated power of the AU, EU and RU is 100W, 50W and 250W, respectively. The ground terminal of the
three-core power socket used at the device installation site must be securely connected to the protective
building ground.
4. Electric shock prevention: touching the internal power supply units is dangerous. To prevent electric
shock, do not perform live-line work.
5. The optical module can support a hot plug, but do not turn the optical fiber head towards any
human body part when plugging it in.
6. During device configuration, upgrading and plugging in units and parts, first disconnect the standby
lithium battery and device power source.
7. When accessing the radio-frequency signal, confirm that the downlink signal is no greater than
10dBm, otherwise the device will not operate normally and damage may occur to the circuit.
8. Natural cooling: Reserve at least 40mm of height above the radiation fins during the device
