In individually powered applications, wire the power supply to each Quad Relay Interface Card. After installation is complete perform the commissioning procedures outlined in Chapter 5. The following sections of this chapter provide a detailed explanation of the installation operations.

LOCATION

 The control system must be installed in a safe area such as a control or equipment room, away from sources of heat, with adequate ventilation and protected from the weather. There are two different System 57 rack configurations to accommodate either front or rear field wiring entry. Each configuration is available in half or full 19" width. The three most common mounting methods are: a. 19" Mounting Frame The System 57 19" 6U front and 3U rear access racks are compatible with the standard 19" (483mm) sub-rack format and may therefore be fitted into any suitable 19" mounting frame. b. Cabinet Wall mounting cabinets are available in two sizes to accommodate the 19" and half 19" 6U front access rack assemblies. c. Panel Alternatively all the racks are suitable for fitting directly into a panel cutout aperture. Power supply units are available, in both 19" and half 19" 1U formats, for applications where an ac input power source is to be used. It is recommended that the power supply units are mounted directly above the System 57 rack.
