User manual OMRON CIMR-J7AZ QUICK MANUAL

[. . . ] Do not connect or disconnect wiring, or perform signal checks while the power supply is turned ON. The Inverter internal capacitor is still charged even after the power supply is turned OFF. To prevent electric shock, disconnect all power before servicing the Inverter, and then wait at least one minute after the power supply is disconnected. Do not perform a withstand voltage test on any part of the Inverter. [. . . ] Never operate the Digital Operator or DIP the switches with wet hands. Never touch the terminals while current is flowing, even if the Inverter is stopping. When the fault retry function is selected, stand clear of the Inverter or the load. (Construct the system to ensure safety, even if the Inverter should restart. When continuous operation after power recovery is selected, stand clear of the Inverter or the load. (Construct the system to ensure safety, even if the Inverter should restart. When the 3-wire sequence is set, do not make the wiring unless the multi-function input terminal parameter is set. Failure to observe this caution may result in harmful burns to the body. Verify the safe working range of the motor and machine before operation. Failure to observe this caution may result in injury and machine damage. If using an Inverter with an elevator, take safety measures on the elevator to prevent the elevator from dropping. Disconnect all power before performing maintenance or inspection, and then wait at least one minute after the power supply is disconnected. If the indicators are not OFF, the capacitors are still charged and can be dangerous. Only authorized personnel should be permitted to perform maintenance, inspections, or parts replacement. Do not connect or disconnect wires, connectors, or the cooling fan while power is applied to the circuit. Periodically inspect the inverter as described the following table to prevent accidents and to ensure high performance with high-reliability. Terminals, unit mounting screws, Connection hardware is properly Properly seat and tighten etc. 8 x 104 Pa, 57 to 85 psi (4 to 6kg / cm2) pressure If dust or oil cannot be removed, replace the inverter unit. Part Replacement Guidelines Part Cooling fan Smoothing capacitor Breaker relays Fuses Aluminium capacitors on PCBs Standard Replacement Period 2 to 3 years 5 years ­ 10 years 5 years Replacement Method Replace with new part. Failure to observe this warning can result in an electric shock or injury and will invalidate the guarantee. Do not subject the Inverter to halogen gases, such as fluorine, chlorine, bromine, and iodine, at any time even during transportation or installation. Note 1: Connect single-phase 200 V AC to terminals R/L1 and S/L2 of the J7AZB Note 2: The braking resistor cannot be connected because no braking transistor is incorporated. [. . . ] Fault Display Fault name and meaning OC Overcurrent Output current is higher than 250% of inverter rated current. UV1 Possible cause and remedy Check output for short circuit or ground fault. Main circuit undervoltage Check correct supply for Inverter being used. Unit overheated Temperature inside the inverter has Check cooling fan (if fitted). [. . . ]
