Debugging
2.1 Installation Overview
2.1.1 Requirements on Installation Site
The outdoor booster could be installed on the wall or floor, and it should be installed close to the
antenna. The requirements of installation site are following:
The installation site should be non-corrosive.
If the cabinet should be mounted on the wall, the wall’s bearing capacity must be more
than 55kg(122lb). Concrete and brick wall are recommended.
2.1.2 Requirements on Anti-corrosion and Shock-protection
To safeguard products and operators, the installing location must be kept away from caustic or
poisonous pollutants. If the site can’t meet seismic, it must be properly reinforced

System Installation
8
2.1.3 Requirements on Illumination, Ventilation and Fire Protection
The installation site should have enough illumination for installation and maintenance needs.
Flammable and explosive material should not be near to the site.
2.1.4 Power requirements
Nominal voltage: 220V AC. Variety range: 180-264 V AC, 47-63 Hz Single Phase.
The power consumption of outdoor booster is about 1,300W. Be certain to select a fuse or a
breaker with the proper capacity. A 10 or 15 ampere breaker is recommended.
2.1.5 Requirements on Lightning Protecting and Grounding
The cross section of grounding cable should be no smaller than #4AWG(25mm2). The grounding
cable should be connected to each ground directly without any splices. Keep the grounding cable
as short as possible.
2.1.6 Installation Preparation
The following tools will be used for a successful installation:
A multimeter
Philips screwdrivers
Flat blade screwdrivers
Wrenches
A Drill
A VSWR testing devices
N adapters
RF testing cables
Power meter (part of hand-held tester)

2.3.1.1 Installation Requirements
Note
The NEC(National Electrical Code) does not allow signal wires to share the same conduit with power wires unless
the signal cable’s voltage range is equal to the power wire’s voltage range.
Avoid bundling signal cable and grounding cable/power cable, keep them separate.
The power cable and grounding cable are supplied, the connectors for the booster end of
power is supplied.
Check open and short circuit before installing the power cable.
