14-1.2.8 Protect lighting fixtures in battery areas from physical damage by guards or
isolation. Receptacles and lighting switches should be located outside of the battery
area.
14-1.2.9 Batteries with a nominal voltage above 250 volts require special installa tion
considerations as detailed in NEC Article 480.6 (2002 Edition) .
14-1.3
Installation Design Considerations.
14-1.3.1 Industry Standards. The installation of a new battery or the replacement of
an existing battery represents a significant effort. Re view the following IEEE standards,
as applicable for the battery type, prior to the installation:
ANSI/IEEE 450, IEEE Recommended Practice for Maintenance, Testing, and
Replacement of Vented Lead-Acid Batteries for Stationary Applications.
ANSI/IEEE 484, IEEE Recommended Practice for Installation Design and
Installation of Vented Lead-Acid Batteries for Stationary Applications.
IEEE 485, IEEE Recommended Practice for Sizing Lead-Acid Batteries for
Stationary Applications.
ANSI/IEEE 1106, IEEE Recommended Practice for Maintenance, Testing, and
Replacement of Vented Nickel-Cadmium Batteries for Stationary Applications.
IEEE 1187, IEEE Recommended Practice for Installation Design and Installation of
Valve Regulated Lead-Acid Batteries for Stationary Applications.
IEEE 1188, IEEE Recommended Practice for Maintenance, Testing, and
Replacement of Valve-Regulated Lead-Acid (VRLA) Batteries for Stationary
Applications.
14-1.3.2 Design Requirements.
14-1.3.2.1 Verify that the selected battery is appropriate for the expected operating
environment. Specifically, determine the average ambient temperature for the
installation location and evaluate if the battery is expected to perform well in the
environment. Temperature has a major impact on the battery's overa ll performance and
service life; ambient temperature extremes must be given careful consideration. If the
battery is to be located in an enclosure, the expected ambient temperature extremes
inside the enclosure should be determined.
14-1.3.2.2 Verify ventilation is adequate for the new installation. If the battery is to be
located in an enclosure (such as a UPS battery), ventilation requirements must be
clearly addressed. The battery area must be ventilated, either by natural or powered
ventilation system, to limit hydrogen accumulation to less than an explosive mixture. If
powered ventilation is required to limit hydrogen buildup, annunciate failure of the
