A summary of the System 57 controller installation procedures is shown below: a. Unpack and check the equipment. b. Identify a suitable location and check the cabling requirements. c. Confirm the power supply requirements. d. Install the Cabinet, 19" Mounting Frame or Panel Cutout as required. e. Fit the System 57 rack into the Cabinet, 19" Mounting Frame or Panel Cutout. f. Install the sensors and wire back to the System 57. g. Check, and if necessary reconfigure, the Single Channel Control Cards. h. Wire the sensors to the Field Interface/Relay Card terminal blocks. i. Wire the outputs from Field Interface/ Relay Card terminal blocks. j. Wire the power supply to the DC Input 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.
UNPACKING
On receipt: a. Carefully unpack the equipment observing any instructions printed on or contained in the packaging. b. Check the contents for transit damage and against the packing note for deficiencies. c. Locate the configuration sheet supplied with the unit and confirm that each channel card type and settings are compatible with the proposed sensors.
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.
