Protective earthing connection is the panel mounting hole of the metal case. (A protective earthing connection stipulated in safety standards is used. The enclosed standard connector for signal I/O is mounted to CN when S8VM is shipped. The enclosed signal I/O connector shorts between 1 and 2, between 3 and 4, and between 7 and 8. Do not connect a load to the output voltage monitor terminals (+V, -V). Output Color Label This color label identifies the output voltage by color.

Do not use the Power Supply in areas outside the derating curves (i. e. , the area shown by shading A in the above graph). When mounting two or more Power Supplies side-by-side, allow at least 20 mm spacing between them. Always provide at least 50 mm of mounting space for the surface with the fan mounted. C) or 100 mm (S8VM-15224C) of mounting space on the opposite side of the surface with the fan mounted. When using the 1, 500-W model for a long period of time at an input voltage of 90 VAC or lower, reduce the load to 80% or less of the above derating curve. The ambient temperature is specified at a location 50 mm in front of the center of the Power Supply's front panel. 300 W 600 W 1, 500 W Note: 1. The internal parts may occasionally deteriorate or be broken due to adverse heat dissipation depending on the mounting status. Do not use the Power Supply in any mounting direction other than those specified. To ensure sufficient cooling, do not cover the air holes located on the side the fan is mounted and the opposite side. Mounting screw tightening torque (recommended value: M4 (1. 27 N·m)) The screws must not protrude more than 6 mm inside the Power Supply. Remote Sensing Function This function is used to compensate for voltage drops on the load lines. Connect the +S pin (pin 2 on CN) to the positive load terminal and the -S pin (pin 4 on CN) to the negative load terminal to enable remote sensing. When not using the remote sensing function, use the standard connector. The +S and +V pins (pin 1 on CN) and the -S and -V pins (pin 3 on CN) will be connected. +V S8VM CN -V -S *1 *2 + Mounting Standard Mounting Correct Correct Correct 300 W *1 600 W *1 1, 500 W *1 +V +S -V Horizontal Mounting Correct Correct Correct Note: 1.

Buzzing Noise when the Input Is Turned ON 50/100/150/300/600/1, 500-W Models A harmonic current suppression circuit is built into the input power. This circuit can create noise when the input is turned ON, but it will last only until internal operation stabilizes and does not indicate any problem in the Power Supply. 300/600/1, 500-W Models The possible cause for no output voltage may be that the overcurrent protection, overvoltage protection, or overheat protection has operated. Alternatively, the built-in fan may have stopped or the remote control function may be OFF. If there is no output voltage even after checking the following points, please contact your OMRON representative. DIN Rail Mounting 15/30/50/100/150/300/600-W Models When mounting to a DIN Rail, lower the S8VM onto the Rail until the Rail stopper clicks into place, hook section A over the edge of the Rail and push in the direction of B. Check the overload protected status. Check whether the load is in overload status or is short-circuited. [. . . ]
