Safety and regulatory information
This section describes important safety and regulatory guidelines that must be observed by personnel installing or
operating PMP 450 equipment.
Important safety information
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
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.
