Make sure to thoroughly understand all instructions in the Instructions Manual before handling this product. Make sure to confirm terminal makings and polarity for correct wiring. Operating ambient temperature and humidity for this product must be within the indicated rating when using this product. 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. 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. Only use this product within a board whose structure allows no possibility for fire to escape. About Installation 1. (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.
