Do not earth (ground) these terminals. Avoid connecting the terminals SD and 5 and the terminals SE and 5. 2) Use shielded or twisted cables for connection to the control circuit terminals and run them away from the main and power circuits (including the 200V relay sequence circuit).
Page 31 INSTALLATION AND WIRING (3) Changing the control logic The input signals are set to sink logic for the NA version, and to source Logic for the EC version. To change the control logic, the jumper connector on the back of the control circuit terminal block must be moved to the other position.

Page 42: Design Information
INSTALLATION AND WIRING 2.2.6 Design information 1) When performing commercial power supply-inverter switchover operation, securely provide electrical and mechanical interlocks for the MC1 and MC2 used for commercial power supply-inverter switchover. When there is a commercial power supply-inverter switchover circuit as shown below, the inverter will be damaged by leakage current from the power supply due to arcs generated at the time of switchover or chattering caused by a sequence error.
Page 43: 2.3 Other Wiring
To improve the power factor, insert a power factor improving reactor on the inverter's primary side or in the DC circuit. For details, refer to the FR-A500/E500 series technical information. 2.3.2...
Page 44 INSTALLATION AND WIRING 2) Measures against noises which enter and cause misoperation of the inverter When devices that generate many noises (which use magnetic contactors, magnetic brakes, many relays, for example) are installed near the inverter and the inverter may be effected by noises, the following measures must be taken: •...
Page 45 INSTALLATION AND WIRING • Data line filter Noise entry can be prevented by providing a data line filter for the detector cable etc. • Data examples By decreasing the carrier frequency, the noise terminal voltage* can be reduced. Use Pr. 72 to set the carrier frequency to a low value (1kHz). Though motor noise increases at a low carrier frequency, selection of Soft-PWM in Pr.
Page 46: Leakage Currents And Countermeasures
INSTALLATION AND WIRING 2.3.3 Leakage currents and countermeasures Leakage currents flow through static capacitances existing in the inverter I/O wiring and motor. Since their values depend on the static capacitances, carrier frequency, etc., take the following measures. (1) To-earth (ground) leakage currents Leakage currents may flow not only into the inverter's own line but also into the other line through the earth (ground) cable, etc.
Page 47: Inverter-Driven 400V Class Motor
INSTALLATION AND WIRING 2.3.4 Inverter-driven 400V class motor In the PWM type inverter, a surge voltage attributable to wiring constants is generated at the motor terminals. Especially for a 400V class motor, the surge voltage may deteriorate the insulation. When the 400V class motor is driven by the inverter, consider the following measures.
Page 48: Peripheral Devices
INSTALLATION AND WIRING 2.3.5 Peripheral devices (1) Selection of peripheral devices Check the capacity of the motor to be used with the inverter you purchased.

Page 54: Earthing (Ec Version)
INSTALLATION AND WIRING 2.3.8 Earthing (EC version) (1) Earthing and Earth Leakage Current (a) Purpose of Earthing Electrical equipment usually has an Earthing Terminal, this must be connected to earth before using equipment. For protection, electric circuits are normally housed inside an insulated case. However it is impossible to manufacture insulating materials that prevent all current from leaking across them, therefore it is the function of the earth (safety earth) to prevent electric shocks when touching the case.
Page 55 INSTALLATION AND WIRING e) The RFI earth should be a braided strap with a 10mm minimum cross sectional area, and as short as possible. f) The earths should be as far away from input and output cables (particularly to equipment sensitive to RFI) as possible, and any distance where they are parallel should be kept to a minimum.

Page 242 OPTIONS Addition of the torque restriction function during acceleration and deceleration (when using the FR-A5AP option) For the former model inverter, the torque restriction level was same regardless of acceleration, deceleration and constant speed. Now you can set torque restriction levels during acceleration and deceleration individually.
Page 243 OPTIONS <When used with communication options > Operation at a communication error occurrence (when a communication option is connected) You can select operation at a communication error occurrence by setting Pr. 500 to Pr. 502 during network operation with a communication option. (not available with the FR-A5NM, FR-A5NP, and FR-A5NR (communication options).) (1) Operation selection at a communication error occurrence 1) Pr.

Page 256: Appendix2 Operating The Inverter Using A Single-Phase Power Supply
APPENDICES Appendix2 Operating the Inverter Using a Single-Phase Power Supply If a single-phase power supply is used to operate the inverter only 4 of the 6 of the diodes will be used. Therefore the ripple current of the capacitor will increase when compared to operation from a three-phase power supply, resulting in a higher temperature rise of the converter and the capacitor.
