553-3001-500 Standard 15.00
External batteries, often used with DC-powered systems, generally require
regular visual inspections. They may also require charger or rectifier tests and
pilot cell tests. Perform all inspections and tests according to the supplier's
instructions.
To comply with safety requirements, consult the following articles before
working with any battery systems:
• Read the "Material Safety Data Sheet" that must be posted to meet
Occupational Safety and Health Administration (OSHA) requirements.
This article outlines appropriate reserve battery handling procedures.
• Refer to National Electric Code 645-10. This article outlines
requirements that call for the installation of AC- and DC-power kill
switches to battery systems in certain environments.
