The Shanghai Synchrotron Radiation Facility (SSRF) is a third-generation synchrotron radiation light source under construction. In SSRF, there are 520 sets of magnet power supplies for the storage ring and 163 sets for injector. All of the power supplies are in PWM switched mode with IGBT. A high precision stable output power supply for 40 dipoles rated at 840A/800V with the stability of ±2·10-5/8hrs will be used for storage ring. 200 sets of chopper type power supply will be used for exciting main winding of quadrupoles respectively. In booster ring, two sets of dynamic power supply for dipoles and two sets for quadrupoles will run at the biased 2Hz sinusoidal wave. All above power supplies will work with digital power supply controllers designed by PSI. All power supplies are being manufactured at professional power supply companies in China.

The engineering design of the mechanical system for the SSRF storage ring was finished. The first group components in each system, such as the magnets, vacuum chambers, BPMs, girders and other hardware, were fabricated and tested, respectively. In order to check the overall design and the installation procedure, a lattice cell prototype was installed by using these components. Based on it, the related utility system was installed and checked. The dynamic properties of the magnet-girder assembly were also tested in this prototype. Most of the design was confirmed during the installation, but still some problems were found. The modification for the overall design and some components design has been made before their mass production. The detail design and installation of the cell installation prototype and the test results are described in this paper.
