3. Installation
3.1. Mechanical Installation
3.1.1. Health and Safety for Mechanical Installation
Read and observe chapter 1.2.
1. Caution: Risk of injury by the considerable weight of the unit falling. Ensure there is
adequate manpower to handle the weight of the system.
2. Caution: Risk of serious personal injury by equipment falling due to improper
installation. The installer must verify that the supporting surface will safely support the
combined load of the electronic equipment and all attached hardware and
components. Only use sufficiently dimensioned screws for mounting and make sure
the mounting material is adequate for the mounting surface.
3.1.2. Property Damage Warnings for Mechanical Installation
1. Attention: Do not install the unit in a way or at a place where the specifications
outlined in the Environmental and Safety Specifications leaflet of the supplier are not
met.
2. Notice: Due to power dissipation, the unit may reach a very high temperature.
Ensure sufficient airflow for ventilation. When mounting the Node AM4 into a train, a
temperature test in maximum configuration (i.e. 4 RF cards) must essentially be
made. A minimum air flow of 50 m³/h is required where the maximum air flow of the
Node AM4 is 220 m³/h which will be reached at an environmental temperature of
around 45°C and above. We suggest to supply the repeater at the air inlet with fresh
air and to conduct warm air at the air outlet off the Node AM4 without feedback in
order to avoid a 'thermal short-circuit'.
3. Notice: It is recommended only to use the mounting hardware delivered by the
manufacturer. If any different or additional mounting material is used, ensure that the
mounting remains as safe as the mounting designed by the manufacturer. Ensure
that the static and dynamic strengths are adequate for the environmental conditions
of the site. The mounting itself must not vibrate, swing or move in any way that might
cause damage to the unit. The specifications for stationary use of the unit must not
be exceeded.
Note: Exceeding the specified load limits may cause the loss of warranty.
4. Notice: Only use sufficiently dimensioned screws for mounting and make sure the
mounting material is adequate for the mounting surface.
5. Notice: Observe that for M12 connectors the nominal torque is 1.0 N-m.
6. Notice: When connecting and mounting the cables (RF, mains, ...) ensure no water
can penetrate into the unit through these cables.
7. Notice: Do not operate the repeater without terminating the antenna connectors. The
antenna connectors may be terminated by connecting them to their respective
antennas or to a dummy load.
Unless otherwise agreed to in writing by CommScope, CommScope’s general limited
product warranty (http://www.commscope.com/Resources/Warranties/) shall be the
warranty governing the Node AMs, including the installation, maintenance, usage and
operation of the Node AMs.
