Important safety information
To prevent loss of life or physical injury, observe the safety guidelines in this section.
Power lines

Working at heights
Exercise extreme care when working at heights.
Grounding and protective earth
PMP 450 units 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 Section 810 of the
National Electric Code, ANSI/NFPA No.70-1984 (USA). 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
Always power down and unplug the equipment before servicing.
Primary disconnect device
The AP or SM unit’s power supply is the primary disconnect device.
External cables
Safety may be compromised if outdoor rated cables are not used for connections that will be exposed to the
outdoor environment.
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 PMP 450 unit before undertaking maintenance activities in front of the antenna.
