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
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, SM, or BHs 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.
