SAFETY
Warning
To prevent loss of life or physical injury, observe the safety guidelines below. In no event shall
Cambium Networks be liable for any injury or damage caused during the installation of the
Cambium ePMP equipment. Ensure that only qualified personnel install ePMP equipment.
Power lines
Exercise extreme care when working near power lines.
Working at heights
Exercise extreme care when working at heights.
Grounding and protective earth
The connectorized ePMP module must be properly grounded to protect against lightning. It is the user’s
responsibility to install the equipment in accordance with national regulations. In the USA follow the
requirements of the National Electrical code NFPA 70-2005 and 780-2004
Installation of Lightning Protection
Systems
. In Canada, follow Section 54 of the
Canadian Electrical Code
. These codes describe correct
installation procedures for grounding the outdoor unit, mast, lead-in wire and discharge unit, size of
grounding conductors and connection requirements for grounding electrodes. Other regulations may apply in
different countries and therefore it is recommended that installation of the outdoor unit be contracted to a
professional installer.
Powering down before servicing
Before servicing ePMP equipment, unplug the power supply from the power source.
Do not disconnect the RJ45 Ethernet cable connectors from the ePMP device while the power supply is on.
Always remove the input power from the power supply.
External cables
Safety may be compromised if outdoor rated cables are not used for connections that will be exposed to the
outdoor environment. For outdoor copper Cat5e Ethernet interfaces, always use Cat5e cable that is shielded
with copper-plated steel. Alternative types of cable are not supported by Cambium Networks.
RF exposure near the antenna
Radio frequency (RF) fields will be present close to the antenna when the transmitter is on. Always turn off the
power to the Access Point or Station before undertaking maintenance activities in front of the antenna.
