The PSU7A Assembly is designed to fit into an ID3000/3000 Series Extended Deep Back Box or a Remote Battery/PSU Enclosure. It requires the PSU to be fitted BEFORE the main chassis. The installation involves securing the PSU Assembly using M4 x 16 SEM screws and nylon spacers. A DTP/Booster module is mandatory with the PSU7A. The document provides detailed steps for fitting the assembly into different enclosures, including wiring connections, mains and safety earth wiring, and specific notes for remote enclosure installations. It also includes a specifications table detailing battery capacity, charge, alarm, and quiescent currents for various configurations. A low voltage shut down feature protects against deep discharge.
