Trial Operation Procedures4- 3Trial Operation ProceduresThe procedure for the trial operate is described in order in this section. Application ConfirmationFirst, confirm the application before using the Inverter.• Fan, blower, pump• Other equipmentFor any Inverter application other than a fan, blower, or pump, set C6-01 (CT/VT Selection) to 0 (CT: low car-rier, constant torque). The default setting is 1 (VT: high carrier, variable torque) for Inverters with SPEC: C orearlier and 0 (CT: low carrier, constant torque) for Inverters with SPEC: E or later.However, only 1(VT) can be set for 200 V Class 110 kW as well as 400 V Class 220 kW and 300 kW Inverterswith any SPEC. Setting the Power Supply Voltage Jumper (400 V Class Inverters of 75 kWor Higher)Set the power supply voltage jumper after setting E1-01 (Input Voltage Setting) for 400 V Class Invertersof 75 kW or higher. Insert the jumper into the power tap nearest to the actual power supply voltage.The jumper is factory-set to 440 V when shipped. If the power supply voltage is not 440 V, use thefollowing procedure to change the setting.1. Turn OFF the power supply and wait for at least 5 minutes.2. Confirm that the CHARGE indicator has gone out.3. Remove the terminal cover.4. Insert the jumper at the position for the voltage supplied to the Inverter (see Fig 4.2).5. Return the terminal cover to its original position.Fig 4.2 Power Supply Voltage Jumper Power ONConfirm all of the following items and then turn ON the power supply.1. Check that the power supply is of the correct voltage.200V Class: 3-phase 200 to 240 VAC 50/60 Hz400V Class: 3-phase 380 to 480 VAC 50/60 HzFor an Inverter of 200 V, 37 kW or more, use one of the following power supplies for the cooling fan.3-phase 200/208/200 VAC 50 Hz or 3-phase 200/208/220/230 VAC 60 HzPower tapJumper (factory-set position)CHARGE indicator200 V Class power supply400V Class power supplyPower supply input terminals
