N142-E1-01 Safety Precautions Precautions for Safe Use Make sure to follow the instructions below to ensure safety. · Outdoors, or places subject to direct sunlight or wearing weather. · Places where dust, iron powder, or corrosive gases (in particular, sulfuric or ammonia gas) exist. 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. 11. For DC input, use a SELV power-supply capable of overcurrent protection. Specifically, a SELV power-supply has a double or reinforced insulation for input and output, and output voltage of 30 Vr. m. s with 42. 4 V at peak or DC60V maximum. 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.
