Preliminary Information

Overview

The Battery Management System for high voltage applications connects

 

to one of the following:

 

A single APC Silcon UPS with pairs of strings.

 

A single non-APC UPS with single strings.

The system provides battery management for nominal 2 V, 6 V, 8 V, or

12V lead-acid batteries; or 1.2 V nickel-cadmium batteries. A system is comprised of at least one AP9921X master unit and up to five AP9921XS expansion units. Each unit supports up to 64 batteries.

Note

For more information on the features and capabilities of the Battery Management System, see the initial sections of the User’s Guide, which is available on the Utility CD supplied with the Battery Management System.

Do not turn on the power to the unit until the wire harnesses are connected and the DIP switches are configured.

Silcon versus non-Silcon installation

This manual covers the installation of two types of systems:

An installation for an APC Silcon battery cabinet

An installation using 5-, 50-, or 100-foot wire harnesses, to be cut at installation to match your battery configuration

The majority of the procedures in this manual are used for both system installations. Disregard Silcon-specific instructions (i.e., midpoint and fuse bus connections) if you are installing a generic harness to fit your battery cabinet or rack that is not for an APC Silcon UPS.
