[. . . ] Product failure may prevent comparative outputs from being generated, resulting in serious accidents. Maintain the power supply voltage within the range specified in the specifications. Check each terminal for correct number and polarity before connecting it. Incorrect or reverse connections may damage or burn out internal components in the product. Provide a switch or circuit breaker so that operators can easily turn OFF the power supply when necessary. Do not use the product where flammable or combustible gases are present. Temperature Meter + Signal input Temperature Meter Power supply input - Surge absorber Application General Precautions 1. Do not use the product in the following locations: · Locations subject to direct radiant heat from heating equipment. · Locations subject to dust or corrosive gases (particularly, sulfuric gas or ammonia gas). Do not block heat dissipation around the product, i. e. , provide sufficient space for heat dissipation. Ensure that the rated voltage is reached within two seconds after the power is turned ON. after power is turned ON for correct measurement. · To prevent inductive noise, separate the terminal block wiring for the product from high-voltage or high-current power lines. Do not route the wiring for the product in parallel with or tie it in a bundle with power lines. Take the following countermeasures against inductive noise in input lines. Temperature Inputs Separate the lead wire that connects the product with a temperature sensor from the load line to prevent the product from being affected by inductive noise. · When using a noise filter for the power supply, check for the voltage and current and install it as close as possible to the Temperature Meter. · Do not install the product near radios, television sets, or wireless devices. Doing so may cause reception interference. Increasing Service Life · Do not use the product in locations where the temperature or humidity exceeds the ratings or where condensation may occur. When installing the product in a panel, be sure that the temperature around the product (not the temperature around the panel) does not exceed the ratings. To extend the product service life, lower the temperature inside the Temperature Meter. · Use and store the product within the temperature and humidity ranges given in the specifications. When gang-mounting Temperature Meters or arranging them vertically, heat generated by the Temperature Meters will cause the internal temperature to rise, reducing the service life. In such cases, consider forced cooling methods, such as using a fan to circulate air around the Temperature Meters.
