ABSTRACT:
This Generic Requirements document (GR) describes a baseline set of requirements applicable to indoor and outdoor battery backup cabinets. These requirements have been derived from the requirement list and testing rationale found in GR-487, Generic Requirements for Electronic Equipment Cabinets.

The indoor/outdoor battery backup cabinet described in this GR consists of the outer-finished closure box along with its integral hardware components, such as:

• Bonding and grounding connections
• Internal walls and braces for splicing chambers and battery compartments
• Frame and shelving tracks
• Doors, seals, and hinges.

• Battery backup cabinets placed inside the outer physical envelope of a building or structure where the space has active environmental controls to control temperature, humidity, and air quality of the ambient space. This includes cabinets located in domed, covered stadiums and enclosed garages.
• Battery backup cabinets placed inside the outer physical envelope of a building or structure where the space has no active environmental controls (e.g., cabinets found in unheated/uncooled mechanical or furnace rooms).

• Battery backup cabinets placed outside the outer physical envelope of a building or structure (e.g., cabinets mounted on roofs, or on the outside of buildings).
• Battery backup cabinets located in open parking garages and open stadiums where the cabinets can be exposed to outside weather conditions and pollution levels.
