Precautions while using Power Supply

Precautions for Safe Use for that Product Do not touch the Product while power is being supplie.
1. Safety precautions
Read the Users Guide and other accompanying documents carefully before handling the motor, installing it in a device or operating it in order to ensure correct usage. Make sure that you have fully familiarized yourself with all the information about the motor, including safety information and precautions before using the motor. The following warnings and cautions are provided in order to ensure safe and correct usage of this product as well as to prevent injury or physical damage to you and others.
2. Grounding
Connect the ground completely. Electric shock may occur if the ground is not connected completely.
3. Operating environment
Use each Product within the rated range for ambient operating temperature, ambient operating humidity, and storage temperature specified for that Product.Use the Power Supply within the ranges specified for vibration and shock resistance.Do not use the Power Supply in locations subject to excessive amount of dust or where liquids, foreign matter, or corrosive gases may enter the interior of the Product.Install the Power Supply well away from devices that produce strong, high frequency noise and surge.Do not use the Power Supply in locations subject to direct sunlight.
4. Mounting
The installation screws can be tightened into the Power Supply only to a limited depth. Make sure that the lengths of the screws protruding into the Power Supply are within the specified dimensions.Refer to the dimensional diagrams for each model for specific dimensions.
5. Wiring
Use caution when connecting the input cable to the Power Supply. The Power Supply Unit may be destroyed if the input cable is connected to the wrong terminals. Use caution when using a model with a DC input. The Power Supply Unit may be destroyed if the polarity is reversed.
6. Wiring materials
Use a wire size that suits the rated output current of the Power Supply to be used in order to prevent smoking or ignition caused by abnormal loads.Caution is particularly required if the output current from one Power Supply is distributed to multiple loads.If thin wiring is used to branch wiring, the Power Supplys overload protection circuit may fail to operate depending on factors such as the impedance of the load wiring even when the load is short circuited. Therefore, insertion of a fuse in the line or other protective measures must be considered.Refer to Technical Guide for Power Supplies to select wiring materials.
7. Precautions against Ingress of Metal Fragments
Drilling on the upper section of an installed Power Supply may cause drilling fragments to fall onto the PCB, thereby short circuiting and destroying the internal circuits. Whether the Power Supply cover is attached or not, cover the Power Supply with a sheet to prevent ingress of fragments when performing work on the upper section of the Power Supply.Be sure to remove the sheet covering the Power Supply for machining before power ON so that it does not interfere with heat dissipation.
8. Load
Internal parts may possibly deteriorate or be damaged if a short circuited or overcurrent state continues during operation.
9. Fan equipped Power Supplies
Power Supplies equipped with a fan have forced air cooling. Do not block the ventilation holes on the fan installation surface and the opposite surface. The cooling effect will decrease if the holes are blocked.Always secure the finger guard when replacing the fan. Always turn OFF the input power before replacing the fan. The input power terminals and internal circuits have a high voltage.Do not touch the internal parts when replacing the fan. Internal parts have a high voltage and high temperature immediately after the input power is turned OFF.Do not allow the removed screws or tools to enter the Power Supply when replacing the fan.Use the specified installation direction and torque specified for each product when replacing the fan.
10. Disassembly
Do not disassemble the Power Supply except when replacing the fan. The products original performance may not be maintained.
