Conforming to Regulations
For all electrical purposes, ensure that your network conforms to applicable country and
local codes, such as the NEC (National Electrical Code) in the U.S.A. If you are uncertain of
code requirements, engage the services of a licensed electrician.
In particular, many codes require that wired electrical devices like the 54 VDC power supply
either terminate in a plug connection or be wired with an on/off switch, and not be hard-
wired to AC/mains.
Protecting Cables and Connections
Cables that move in the wind can be damaged, impart vibrations to the connected device,
or both. At installation time, prevent these problems by securing all cables with cable ties,
cleats, or weather-resistant tape.
The cable can be a path for water to follow to enter the cable connector or even the module.
You can prevent this problem by including and securing a drip loop where the cable enters
the module enclosure.
Testing the Components
The best practice is to connect all the components - BHs, APs, uGPS antenna, and CMM5 -
in a test setting and initially configure and verify them before deploying them to an
installation. However, circumstances or local practice may require a different practice.
Unpacking Components
When you receive products, carefully inspect all shipping boxes for signs of damage. If you
find damage, immediately notify the transportation company.
As you unpack the equipment, verify that all the components that you ordered have arrived.
Save all the packing materials to use later, as you transport the equipment to and from
installation sites.
