POWER SOURCES

GENERAL

Electronic equipment almost always depends on electrical energy for its operation. Electric power sources availing of electronic technology developments in efforts to support the steadily increasing industry emphasis on reliability and performance of electronic systems and equipment have attained a certain degree of sophistication. Consideration of the system and equipment performance is coupled with the demand for protection of person and properties from hazards resulting from the operation and use of power sources for electronic equipment and system in particular.

Applicability

This section establishes safety provisions on the installation, operation and use of power sources and devices for electronic equipment and systems.

Considerations

Foreign potential hazards, strength requirements and environmental hazards due to the operation of power systems and devices are the primary consideration of this section with performance being touched only when related to any of the above three consideration.

CONSTRUCTION AND PROTECTION REQUIREMENTS

Storage Batteries and Chargers

This section applies to all stationary installation of storage batteries for use with or associated with equipment used with electronic equipment, devices or system except consumer products.

A. Batteries should be located where temperatures range between 15.5 and 32.2 degrees Celsius (60° and 90°F). Higher temperatures will shorten battery life and lower temperature will decrease the ampere-hour capacity and may damage the battery by freezing...
