observed by personnel installing or operating PTP 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
PTP 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 BHM or BHS unit’s power supply is the primary disconnect device.
External cables
Safety may be compromised if outdoor rated cables are not used in connections
for those exposed to the outdoor environment.
