Ｅ６５８１５９０2CautionProhibited・Do not install in any area where the unit would be subject to large amounts of vibration.That could result in the unit falling, resulting in injury.■ WiringWarningProhibited・Do not connect this option to the inverter doesn’t have the DC terminals (PA/+, PC/-).That will destroy both the inverter and the option, and may result in fire.・Do not connect AC power supply to the DC terminals, PA1 and PA2, of the option or theDC terminals, PA/+ and PC/-, of inverter. That may cause a fire.・Within 15 minutes after turning off input power, do not touch wires of devices (MCCB)connected to the input side of the inverter or the DC terminals of both inverter and option.That could result in electric shock.MandatoryAction・Electrical construction work must be done by a qualified expert.Connection of input power by someone who does not have that expert knowledge mayresult in fire or electric shock.・Wiring must be done after installation.If wiring is done prior to installation that may result in injury or electric shock.・The following steps must be performed before wiring.(1) Turn off all input power to the inverter.(2) Wait at least 15 minutes and check to make sure that the charge lamp of inverter isno longer lit.(3) Use a tester that can measure DC voltage 800VDC or more, and check to make surethat the voltage to the DC main circuits (between PA/+ and PC/-) is 45V or less.If these steps are not properly performed, the wiring will cause electric shock.・Connect correctly the DC terminals, PA1 and PA2, of the option from DC power source +to the DC terminals PA/+ of inverter with the same polarity.If the polarity is incorrect, it will destroy both the inverter and the option, and may result infire.・Tighten the screws on the terminal board to specified torque.If the screws are not tightened to the specified torque, it may lead to fire.・Check to make sure that the input power voltage is +10% of the rated power voltagewritten on the rating label *√2 (±10% when the load is 100% in continuous operation).If the input DC power voltage is over the rated power voltage described above, this mayresult in fire.・Connect the output signal of standby, STA, STB and STC, to the inverter’s controlsystem.If inverter drives in case of the output signal of standby OFF, this may result in fire.・Ground must be connected securely.If the ground is not securely connected, it could lead to electric shock or fire when amalfunction or current leak occurs.Be Grounded |
