[. . . ] Make sure that no weight rests on the product after installation. 10. To enable an operator to turn off this product easily, install switches or circuit breakers that conform to relevant requirements of IEC60947-1 and IEC60947-3, and label them appropriately. Precautions for Correct Use For Proper Use 1. Do not use the product in the following locations. · Places subject to radiant heat from heat generating devices. · Places subject to vibrations or physical shocks. Make sure to use setting values appropriate for the controlled object. Failure to do so can cause unintended operation, and may result in accident or corruption of the product. Do not use thinner or similar solvent for cleaning. When discarding, properly dispose of the product as industrial waste. Only use this product within a board whose structure allows no possibility for fire to escape. About Installation 1. When wiring, use only recommended crimp terminals. Do not block areas around the product for proper dissipation of heat. (If you do not secure space for heat dissipation, life cycle of the product will be compromised. ) 3. To avoid electrical shocks, make sure that power is not supplied to the product while wiring. To avoid electrical shocks, make sure that power is not supplied to the product when performing DIP switch settings. Noise Countermeasures 1. Do not install the product near devices generating strong high frequency waves or surges. When using a noise filter, check the voltage and current and install it as close to the product as possible. In order to prevent inductive noise, wire the lines connected to the product separately from power lines carrying high voltages or currents. Do not wire in parallel with or on the same cable as power lines. Other measures for reducing noise include running lines along separate ducts and using shield lines. To avoid faulty operations, malfunctions, or failure, observe the following operating instructions. 1. When turning on the power, make sure to realize rated voltage within 1 second from the time of first supply of electricity. Make sure to use power supply for operations, inputs, and transformer with the appropriate capacity and rated burden.
