Safety and regulatory information
This section describes important safety and regulatory guidelines that must be observed by
personnel installing or operating ePMP equipment.
Important safety information
Warning To prevent loss of life or physical injury, observe the safety guidelines in this
section.
Power lines
Exercise extreme care when working near power lines.
Working at heights
Exercise extreme care when working at heights.
Grounding and protective earth
ePMP devices and mounting structures must be properly grounded to protect against lightning. It is
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 be contracted to a professional installer.
Powering down before servicing
Always power down and unplug the equipment before servicing.
Primary disconnect device
The ePMP 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
Strong radio frequency (RF) fields will be present close to the antenna when the transmitter is on.
Always turn off the power to the ePMP device before undertaking maintenance activities in front of
the antenna.
Minimum separation distances
Install the ePMP device so as to provide and maintain the minimum separation distances from all
persons.
The minimum separation distances for each frequency variant are specified in Calculated distances
and power compliance margins on page 6-73.
