Battery Management System — Installation |
Overview
System Information
The American Power Conversion (APC®) Battery Management System connects to one of the following:
•A single UPS with one string of up to 244 lead-acid batteries or 375 nickel-cadmium batteries.
•A single UPS with two strings of up to 244 lead-acid batteries or 256 nickel-cadmium batteries.
The system provides battery management for nominal 2 V, 4 V, 8 V, or 12 V lead-acid batteries; or 1.2 V or 2.4 V nickel-cadmium batteries. A system is comprised of one AP9921X master unit and up to seven AP9921XS expansion units. Each unit supports up to 64 batteries.
For more information on the features and capabilities of the Battery Management System, see the initial sections of the Battery Management System User’s Guide, which is available on the supplied Utility CD.
Note: Do not turn on the power to the system until the DIP switches are configured and the wire harnesses are connected to the Battery Management System and the batteries.

Safety Information
Electrical Hazard: Risk of electric shock—battery cabinets contain potentially lethal voltages! Batteries are energized even when AC power has been disconnected.
All electrical equipment must be rated for the voltage of your Battery Management System.
Warning: Only qualified personnel, trained in battery operation and safety, may install the harnesses. Keep unauthorized personnel away from the batteries.
When installing the Battery Management System:
•Cover the batteries with an electrical insulating blanket before installing the harnesses.
•Wear rubber gloves, rubber boots, and safety goggles.
•Use double-insulated tools.
•Do not short-circuit the battery terminals; this could cause the batteries to explode.
•Do not lay tools or metal parts on top of the batteries or near the cable lugs.
•Remove watches, rings, and other metal objects.
•For the UPS and switch gear, use lock-out/tag-out safety procedures (which remove access to a device and physically label the device as intentionally out of service) before working on the batteries.
•Use only cables supplied by APC unless otherwise indicated.
•Avoid skin contact with battery components, such as electrolyte.
Lockout/Tagout the UPS
Note: Lockout/Tagout safety procedures remove access to a device and physically label the device as intentionally out of service.
Before installing the Battery Management System, use lockout/tagout safety procedures for the UPS and any attached equipment, such as high-voltage power supplies. If possible, disconnect the main output lead from the battery string to the load.
Electrical Hazard: Voltage is present in the battery cabinet even after disconnecting from the main load. Use caution when working with the batteries.
Each battery should be treated as though the entire string voltage were present at its terminals.
