INSTALLATION AND WIRING 2.2.5 Connection of stand-alone option units The inverter accepts a variety of stand-alone option units as required. Incorrect connection will cause inverter damage or an accident. Connect and operate the option unit carefully in accordance with the corresponding option unit manual. (1) Connection of the dedicated external brake resistor (option) Connect a brake resistor across terminals + and PR.
Page 43
INSTALLATION AND WIRING (3) Connection of the FR-HC high power factor converter (option unit) (In the case of single-phase power input, the FR-HC cannot be connected.) When connecting the high power factor converter (FR-HC) to suppress power harmonics, wire as shown below. Wrong connection will damage the high power factor converter and inverter.
INSTALLATION AND WIRING 2.2.6 Design information 1) Provide electrical and mechanical interlocks for MC1 and MC2 which are used for commercial power supply-inverter switch-over. When there is a commercial power supply-inverter switch-over circuit as shown below, the inverter will be damaged by leakage current from the power supply due to arcs generated at the time of switch-over or chattering caused by a sequence error.
2.3 Other Wiring INSTALLATION AND WIRING 2.3 Other wiring 2.3.1 Power supply harmonics Power supply harmonics may be generated from the converter section of the inverter, affecting the power supply equipment, power capacitor, etc. Power supply harmonics are different in generation source, frequency band and transmission path from radio frequency (RF) noise and leakage currents.
INSTALLATION AND WIRING 2.3.2 Inverter-generated noise and reduction techniques Some noises enter the inverter causing it to incorrectly operate, and others are radiated by the inverter causing misoperation of peripheral devices. Though the inverter is designed to be insusceptible to noise, it handles low-level signals, so it requires the following basic measures to be taken.
Page 47
INSTALLATION AND WIRING 3) Measures against noises which are radiated by the inverter causing misoperation of peripheral devices. Inverter-generated noises are largely classified into those radiated by the cables connected to the inverter and inverter main circuit (I/O), those electromagnetically and electrostatically inducted to the signal cables of the peripheral devices close to the main circuit power supply, and those transmitted through the power supply cables.
Page 48
INSTALLATION AND WIRING Noise Path Measures When devices which handle low-level signals and are susceptible to misoperation due to noise (such as instruments, receivers and sensors) are installed near the inverter and their signal cables are contained in the same panel as the inverter or are run near the inverter, the devices may be misoperated by air-propagated noise and the following measures must be taken: (1) Install easily affected devices as far away as possible from the...

INSTALLATION AND WIRING 2.3.3 Leakage currents and countermeasures Due to the static capacitance existing in the inverter I/O wiring and motor, leakage currents flow through them. Since their values depend on the static capacitance, 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 lines through the earth (ground) cable, etc.
INSTALLATION AND WIRING z Countermeasures y Use the electronic overcurrent protection of the inverter. y Decrease the carrier frequency. Note that motor noise increases. Selection of Soft-PWM will make it unoffending. To ensure that the motor is protected against line-to-line leakage currents, it is recommended to use a temperature sensor to directly detect motor temperature.
