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. 2. 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. 3. Do not use thinner or similar solvent for cleaning. Use commercial alcohol. 4. When discarding, properly dispose of the product as industrial waste. 5. 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. 2. 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. 4. 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. 2. When using a noise filter, check the voltage and current and install it as close to the product as possible. 3. 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. 2. Make sure to use power supply for operations, inputs, and transformer with the appropriate capacity and rated burden. 3. Maintenance and handling of this product may only be performed by qualified personnel. 4. Distortion ratio of input wave forms must be 30% or less. Use of this product with circuits that have large distortion in wave forms may result in unwanted operations. 5. Using this product for thyristor controls or inverters will result in errors. 6. When setting the volume, adjust the control from the minimum side to the maximum side. 6 Single-phase Voltage Relay K8AB-VW Cat.
