Abstract

Specifies requirements for the installation of sealed secondary batteries permanently installed in buildings.

Scope

This Standard sets out requirements for the installation of sealed secondary batteries with a nominal voltage exceeding 24 V and a capacity exceeding 10 A.h at the 1 h rate of discharge, permanently installed in or on buildings, structures or premises to ensure safety from fire and electric shock. AS 2676.2 provides guidance on the installation and maintenance of sealed secondary batteries. This Standard covers sealed cells only. The installation and maintenance of vented cells are covered by AS 3011.1 and AS 2676.1.
NOTE: Requirements specifically applicable to the design and installation of extra-low voltage (d.c.) power supplies that are used by telecommunications carriers in the provision of public telecommunications networks are given in AS 3015 (Int)-1991, Electrical installations - Extra-low voltage (d.c.) power supplies in public telecommunications networks.
