Admissible DIN rails: TS35/7.5 or TS35/15. To attach the SDR-480P to the rail: 1. Rotate the SDR-480P backwards, as shown in the figure. 2. Fit the top of the SDR-480P over the top hat rail. 3. Slide the SDR-480P downwards until it hits the stop. 4. Push the bottom of the SDR-480P forward until it snaps into place. 5. Move the SDR-480P back and forth to make sure it is locked in place. Installation 1. To prevent the unit from overheating, always allow sufficient clearance around the unit for proper ventilation: 5 mm left and right, 40 mm above, and 20 mm below. You should also keep a 10 to 15 cm clearance from adjacent devices that act as a heat source. 2. The appropriate mounting orientation is vertical, with input terminals on the bottom and output on the top of the SDR-480P. Other mounting orientations, such as upside down, horizontal, or table-top, are not allowed. 3. Use copper wire only; the recommended wiring is shown below. AWG 18 16 14 12 10 Rated Current (Amps) 6 6-10 13-16 16-25 25-32 Lead cross-section (mm2) 0.75 1.00 1.5 2.5 4 Note: When 5 or more wires are connected to the unit, the current carried by each wire could be 20% less than the current listed above. Make sure that all strands of each wire are properly inserted into the terminal connection, and that the screw terminals are securely fixed to prevent poor contact. If the power supply has multiple output terminals, make sure each contact is connected to wires to prevent stress on a single contact from too much current. 4. Use wire that can withstand temperatures of at least 80°C, such as UL1007. 5. Suggested fuses and the maximum number of the PSUs that can be connected to a circuit breaker at 230 V are shown as below: Model Fuse Circuit breakers C16 D16 SDR-480P T8A/L250V 4 4 6. The recommended wire strapping length is 5 mm (0.197 inch). 7. Use a slotted type 4 mm screwdriver. 8. Use the following torque settings for terminals: Model I/P O/P SDR-480P 5 kgf-cm (4.4 in-lb) 8 kgf-cm (7 in-lb)
