User manual OMRON G3PW

[. . . ] New Product Single-phase Power Controller G3PW High-precision Control with Easy Setup · Precise heater burnout detection. · Set value and present value monitoring with indicators. · Phase control or optimum cycle control. · RS-485 communications to set manipulated variables and monitor load current. [. . . ] · Locations subject to water, oil, or chemicals · Locations subject to direct sunlight · Locations where dust or corrosive gases (in particular, sulfuric or ammonia gas) are present · Locations subject to extreme temperature changes · Locations where icing or condensation may occur · Locations subject to excessive shocks or vibration · Locations subject to direct heat radiated from heating devices Safety Measures and Checking · Install a switch or circuit breaker so that the operator can immediately turn OFF the power, and provide a suitable display. · Apply the power supply voltage through the contacts of a switch, relay, or similar device so it reaches the rated voltage within 2 s. If the power supply voltage is increased gradually, the power supply may not be reset or outputs may malfunction. · Use a power supply voltage, input voltage, input current, and load within the specifications and rated ranges for the Power Controller. · Use a load that draws a current at the maximum output that is within the rated current range of the Power Controller. If the current drawn by the load is not within the rated current range, malfunction or fire may occur. · Make sure that the protective cover is attached to the load terminal block before using the Power Controller. Failure to do so may damage internal components due to mechanical stress. Preventing Inductive Noise · Allow as much space as possible between the Power Controller and devices that generate powerful high frequencies (highfrequency welders, high-frequency sewing machines, etc. ) or surge. · Keep the signal lines that connect to the Power Controller's terminal block away from power cables carrying high voltages or large currents. Also, do not wire power lines together with or parallel to Power Controller wiring. Using shielded cables and using separate conduits or ducts is recommended. · Attach a surge suppressor or noise filter to peripheral devices that generate noise (in particular, motors, transformers, solenoids, magnetic coils or other equipment that have an inductance 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 Power Controller. Installation and Wiring · When installing the Power Controller, always securely tighten the top mounting screws first. When removing the Power Controller, always remove the bottom mounting screws first. · Take safety measures, such as wearing safety shoes, in case the Power Controller falls. · Touch the Power Controller only after first touching a grounded metal object to discharge any static electricity from your body. · Always ground the Power Controller to 100 or less. There are no ground terminals provided, so use the heat sink mounting screws as ground terminals. · Check the terminal number and polarity for each input before connecting it. · Use copper twisted wire in the sizes specified in this Instruction Sheet. · Use insulated crimp terminals with insulation sleeves. If using crimp terminals that are not insulated, cover them with insulation sleeves. [. . . ] · DIN Track mounting types and screw mounting types are available. All DIN Track mounting types mount to DIN Track (applicable DIN Track: TR35-15Fe (IEC 60715)). · Certification pending for UL, CSA, and EN (TÜV certification). 13 MEMO 14 Warranty and Application Considerations Read and Understand This Catalog Please read and understand this catalog before purchasing the products.
