0.1. Safety Instructions
Before installing and operating the IDAS, read and comply with the following safety instructions:
1. Engineering design: The IDAS 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 fibre 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.
