Improper operation may result in slight to medium injury or property damage. Note: More serious situations than those cov- ered by the CAUTION sign can result depending on the circumstances. It is important that you always follow the in- structions. Safety Instructions 1 FVR-C11S-EN Compliance with UL/cUL standards [Applicable to products with UL/cUL mark] 1. [WARNING] Take care of electric shock. Be sure to turn the inverter off before starting work. CAUTION 2. [CAUTION] When the charge lamp is lit, the inverter is still charged at a dangerous voltage. 3. [WARNING] There are two or more live parts inside the inverter. 4. The inverter is approved as a part used inside a panel. Install it in- side a panel. 5. Perform wiring to the input, output and control terminals of the in- verter, referring to the table below. Use UL certified round crimp terminal to the input and output terminals with insulation cover or covered with reduced tube to obtain the insulation distance. Use a crimping tool recommended by the terminal manufacturer when fabricating crimp terminals. 6. Install a fuse in the power supply to the inverter, referring to the ta- ble below.

Do not use the inverter brake function for mechanical holding. WARNING Otherwise injuries could occur. 1. When the retry function is selected, the in- verter may automatically restart after trip- ping, depending on the cause of the trip. (Design the machine to secure personal safety in the event of restart.) Otherwise accident could occur. 2. Operating conditions may occasionally be different from the preset acceleration/de- celeration time or speed because of activa- tion of the stall prevention function. In such a case, personal safety must be se- cured through adequate machine design. Otherwise accident could occur. 3. The stop key is effective only when a func- tion setting has been established. Therefore install an emergency switch in- dependently. When operation via the ex- ternal signal terminal is selected, the STOP key on the keypad panel will be disabled. There is a risk of accidents. 4. Operation starts suddenly if alarm reset is done with an running signal input. Check that no running signal is input before alarm reset. Otherwise accidents could occur.

Otherwise electric shock could occur. 2-3 Connection Remove the surface cover to connect the termi- nal blocks. Correctly connect them according to the following procedures. 2-3-1 Basic connection 1. Always connect the power to the main power supply input terminal of the inverter. If it is connected to another terminal, the inverter will be damaged (see Figure 2-3-1). 2. Always ground the ground terminal to prevent disasters such as fire and electric shock and to minimize noise. 3. Use a reliable crimp terminal for connection between a terminal and wire. 4. After terminating the connection (wiring), check the following items: a. Whether the connection is correct b. Whether all necessary connections have been made c. Whether there is a short-circuit or ground fault between terminals and wires 5. Connection modification after power-on The smoothing capacitor in the direct current part of the main circuit cannot be discharged quickly after the power is turned off. Use a multimeter to check that the voltage of the di- rect current (DC) is reduced to the safety range (25V DC or less) after the charge lamp goes off to avoid danger. Check that the volt- age is zero before short-circuiting a circuit be- cause the residual voltage (electric charge) may cause sparks. 2 Installation and Connection 2-3 2 2 FVR-C11S-EN 2-3-2 Connecting the main circuit and ground terminals Symbol Name Explanation L1/L,L2/N Main power supply input Connects single-phase power (Single-phase 200V input).

Even if the output from the inverter is stopped, you will be get an electric shock when you touch the main circuit terminals such as inverter output terminals U, V and W if the voltage is supplied to the main power supply input terminal. The smoothing capacitor in the inverter has been charged when the power is turned off and it is not discharged immediately. Before touch- ing the electric circuit, wait until at least five min- utes have elapsed after power-off and the charge lamp is off, indicating the voltage is al- ready low. After checking normality in the above trial run, start operation. WARNING 1. The STOP key is valid only when the func- tion has been set. Assign another switch to emergency stops. Otherwise accidents could occur. 2. Operation starts suddenly if alarm reset is done with an running signal input. Check that no running signal is input before alarm reset.
