24 Precautions UTON o not touch the terminals while power is being supplied. oing so may occasionally result in minor injury due to electric shock. o not touch the terminals or the electrical components or patterns on the P within minute after turning O the power supply. oing so may occasionally result in minor injury due to electric shock. o not allow pieces of metal, wire clippings, or fine metallic shavings or filings from installation to enter the product. oing so may occasionally result in electric shock, fire, or malfunction. o not use the product in locations where flammable or explosive gases are present. oing so may occasionally result in minor or moderate explosion, causing minor or moderate injury, or property damage. Tighten the screws on the terminal block to the following specified torque. Loose screws may occasionally cause fire, resulting in minor or moderate injury, or damage to the equipment. Terminal block screws: 0.0 to 0. N m Perform correct setting of the product according to the application. ailure to do so may occasionally cause unexpected operation, resulting in minor or moderate injury, or damage to the equipment. malfunction in the Product may occasionally make control operations impossible or prevent alarm outputs, occasionally resulting in property damage to the system or equipment connected to the Product. To maintain safety in the event of malfunction of the Product, take appropriate safety measures, such as installing a monitoring device in a separate system. o not use the equipment for measurements within measurement categories,, or V (according to E00-). oing so may occasionally cause unexpected operation, resulting in minor or moderate injury, or damage to the equipment. Use the equipment for measurements only within the measurement categories for which the product is designed. The service life of the output relays depends on the switching capacity and switching conditions. onsider the actual application conditions and use the product within the rated load and electrical service life. Using the product beyond its service life may occasionally result in contact welding or burning. o Not disassemble, modify, or repair the product or touch any of the internal parts. Minor electric shock, fire, or malfunction may occasionally occur. Precautions for Safe Use. Use and store the igital ontroller in the range of specifications for ambient temperature and humidity. The service life will decrease due to increased internal temperature if multiple igital ontrollers are mounted closely side by side or one on top of the other. f this type of mounting is used, use forced cooling, e.g., use a fan to blow air onto the igital ontrollers.. o not prevent heat dissipation by obstructing the periphery of the igital ontroller. o not block the vents on the igital ontroller unit.. The supplied power voltage and load must be within the rated and specified ranges.. e sure to confirm the name and polarity for each terminal before wiring the terminal block.. o not connect anything to unused terminals.. Use the specified size of crimp terminals (M, width:.8 mm max.) to wire the terminal block. When connecting bare wires, use copper stranded or solid wires, and use WG (cross-sectional area of 0. mm ) to WG (cross-sectional area of.08 mm ) for the power supply terminals and WG8 (crosssectional area of 0.08 mm ) to WG (cross-sectional area of.09 mm ) for other terminals. (Length of exposed wire: to 8 mm) 7. Ensure that the rated voltage is attained within seconds after turning ON the power. 8. Turn O the power first when you need to draw out the igital ontroller. o Not touch the terminals or the electronic components, or subject them to physical shock. When inserting the igital ontroller, do not allow the electronic components to contact the case. 9. o not remove the inner circuit board. 0. The output may turn O when shifting to certain levels. Take this into consideration when performing control.. llow a warm-up time of at least 0 minutes.. To prevent inductive noise, separate the igital ontroller terminal block wiring from power lines that carry high voltages or high currents. lso, do not wire power lines together with or parallel to the igital ontroller wiring. Using shielded cables and separate conduits or ducts is recommended. ttach a surge suppressor or noise filter to peripheral devices that generate noise (in particular, motors, transformers, solenoids, magnetic coils, or other equipment that has an inductive component). When a noise filter is used at the power supply, first check the voltage or current, and attach the noise filter as close as possible to the product. llow as much space as possible between the product and devices that generate powerful high frequencies (e.g., high-frequency welders, high-frequency sewing machines) or surge.. nstall a switch or circuit breaker that allows the operator to immediately turn O the power, and label suitably.. The product is designed for indoor use only. o not use the product outdoors or in any of the following locations. Locations where dust or corrosive gas is present (in particular, sulfur or ammonia gases) Locations where condensation or ice may form Locations directly exposed to sunlight Locations subject to strong shocks or vibration Locations where water or oil may splatter on the igital ontroller Locations directly exposed to radiant heat from heating equipment Locations subject to sudden or extreme changes of temperature. o not use paint thinner or similar chemical to clean with. Use standard grade alcohol. Programmable igital ontroller ER-T/EER-T

25 . Some inverters are labeled as having an output frequency of 0/ 0 Hz. Smoke or burning, however, may occur due to increased temperature in the igital controller. o not use an inverter output as the power supply for the igital ontroller. Precautions for orrect Use Service Life Use the product within the following temperature and humidity ranges: Temperature: 0 to (with no icing or condensation) Humidity: % to 8% When the product is installed inside a control panel, make sure that the temperature around the product, not the temperature around the control panel, does not exceed. The service life of this product and similar electronic devices is determined not only by the number of switching operations of relays but also by the service life of internal electronic components. omponent service life is affected by the ambient temperature: the higher the temperature becomes, the shorter the service life becomes and, the lower the temperature becomes, the longer the service life becomes. Therefore, the service life can be extended by lowering the temperature of the product. e sure to install the product according to the specified conditions. Otherwise, the heat generated by the product will cause the internal temperature to rise, shortening the service life. f necessary, cool the product using fans or other means of air ventilation. When providing forced cooling, however, be careful not to cool down the terminals sections alone to avoid measurement errors. Noise ountermeasures To prevent inductive noise, separate the wiring for the product's terminal block and connector from high-voltage, high-current power lines. o not run the wiring parallel to or in the same cable as power lines. The influence of noise can also be reduced by using separate wiring ducts or shield lines. nstall surge absorbers or noise filters in devices near the product that generate noise (in particular, devices with an inductance component, such as motors, transformers, solenoids, and magnetic coils). f a noise filter is used for the power supply, check the voltage and current, and install the noise filter as close as possible to the product. Separate the product as far as possible from devices generating strong high-frequency noise (e.g., high-frequency welders and highfrequency sewing machines) or surges. Measurement ccuracy When extending the thermocouple lead wire, be sure to use a compensating wire that matches the thermocouple type. When extending the lead wire of the platinum resistance thermometer, be sure to use wires that have low resistance, and make sure that the resistances of the three lead wires are the same. f the measurement accuracy is low, check whether the input shift is set correctly.
