Installing the CMM5: Preparation

Ensure that you comply with standard local or national electrical and climbing procedures when you install the CMM5.


Installing a CMM involves electrical power and can involve height and exposure to RF (Radio Frequency) energy. To avoid personal injury, know and follow applicable national and local safety regulations and industry best practices, and follow the specific guidelines in this document

Equipment is intended for installation in Restricted Access Area" /“Les matériels sont destinés à être installés dans des EMPLACEMENTS À ACCÈS RESTREINT.

Avoiding Hazards

Use simple precautions to protect staff and equipment. Hazards include exposure to RF waves, lightning strikes, power lines, and power surges. This section specifically recommends actions to abate these hazards.

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, cnPulse, 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.
