Page 10: Thermal Imaging System - Installation Overview
Thermal Imaging System Thermal Imaging System - Installation Overview The NIR Borescope Thermal Imaging System comprises a thermal imaging borescope camera which is designed to be installed inside a protective enclosure. The enclosure has air purging and water cooling facilities. This protective enclosure is designed to be installed in a furnace via a standpipe assembly. -
Page 11: Electrical Connections
Installation Guide NIR Borescope Thermal Imaging System Electrical Connections The basic system electrical connections are as follows: • Mains input to the TRACO Power Supply Unit; • 24V output from TRACO Power Supply Unit to Terminal/Ethernet Box; • 8-Way cable from Terminal Box to NIR Camera; • Ethernet Cable from NIR Camera to Terminal/Ethernet Box •... - Page 12 NIR Borescope Installation Guide Thermal Imaging System The connection terminals inside the input connector will now be revealed (Fig. 3-4). Unscrew the connector front section from the Power Supply Unit and disassemble the remaining parts of the connector. Slide the rear locking ring, gasket and shell body over the mains input cable.
- Page 13 Installation Guide NIR Borescope Thermal Imaging System Connecting the 24V output from the TRACO PSU to the Terminal Box Attach the 24V DC output cable to the Output connector of the Power Supply Unit (Fig. 3-8). Fig. 3-8 Open the lid of the Terminal Box to reveal the connection terminals on the DIN Rail.
- Page 14 NIR Borescope Installation Guide Thermal Imaging System Connecting the cables from Terminal Box to NIR Camera Connect one end of the 8-way cable to the connector on the terminal box. Note: Align the red marker on the pre-wired plug with the red marker above the keyway in the socket on the terminal box and push in the cable (Fig.
- Page 15 Installation Guide NIR Borescope Thermal Imaging System Slide the M25 Conduit Gland and the Cable Seal Washer over the free end of the 8-way cable. The rubber Conduit Cable Seal is split lengthways and is designed to clamp around the cable. Fit the Seal so that it is approximately 150mm (6in) from the 8-way connector (Fig.
- Page 16 NIR Borescope Installation Guide Thermal Imaging System 25) Once again, ensure that the seal is fitted that it is approximately 150mm (6in) from the Ethernet connector (Fig. 3-20). The Back-cap is now ready to be fitted to the protective housing. Fig. 3-20 Connecting the Cables from the Terminal Box to the Camera This procedure will complete the installation of the Camera in the protective enclosure.
