1 2 3 5 5 6 7 8 9 10 • To prevent an electric shock, always earth (ground) the motor and inverter. • Do not install a power factor correction capacitor or surge suppressor or capacitor type filter on the inverter's output side. Doing so will cause the inverter to be shut off or the capacitor and surge suppressor to be damaged. If any of the above devices is connected, immediately remove it. When installing a molded case circuit breaker on the output side of the inverter, contact the • Electromagnetic wave interference manufacturer of the molded case circuit breaker.
The input/output (main circuit) of the inverter includes high frequency components, which may interfere with the communication devices (such as AM radios) used near the inverter. In such a case, install the optional radio noise filter FR- BIF (for use in the input side only) or line noise filter FR-BSF01 or FR-BLF to minimize interference. (Refer to page 52 ). • For details of options and peripheral devices, refer to the respective Instruction Manual. 17 2. INSTALLATION AND WIRING 2.1 Peripheral devices Symb ol Name Overview Refer to page (a) Inverter (FREQROL-CS80) The life of the inverter is influenced by the surrounding air temperature.
The surrounding air temperature should be as low as possible within the permissible range. This must be noted especially when the inverter is installed in an enclosure. Incorrect wiring may lead to damage of the inverter. The control signal lines must be kept fully away from the main circuit lines to protect them from noise. 23, 29 (b) AC power supply Must be within the permissible power supply specifications of the inverter. 238 (c) Molded case circuit breaker (MCCB), earth leakage circuit breaker (ELB), or fuse Must be selected carefully since an inrush current flows in the inverter at power ON. 18 (d) Magnetic contactor (MC) Install this to ensure safety.
Do not use this to start and stop the inverter. Doing so will shorten the life of the inverter. 58 (e) AC reactor (FR-HAL) Install this to suppress harmonics and to improve the power factor. An AC reactor (FR-HAL) (option) is required when installing the inverter near a large power supply system (500 kVA or more). Under such condition, the inverter may be damaged if you do not use a reactor. Select a reactor according to the applied motor capacity. 57 (f) Noise filter (FR-BLF) Install this to reduce the electromagnetic noise generated from the inverter. The noise filter is effective in the range from about 0.5 to 5 MHz. A wire should be wound four turns at maximum.
50 (g) High power factor converter (FR-HC2) Suppresses the power supply harmonics significantly. Install this as required. 44 (h) Power regeneration common converter (FR-CV) Provides a large braking capability. Install this as required. 45 (i) Radio noise filter (FR-BIF) Install this to reduce the radio noise. — (j) Brake unit (FR-BU2) Allows the inverter to provide the optimal regenerative braking capability. Install this as required. 42 (k) Resistor unit (FR-BR) (l) Noise filter (ferrite core) (FR-BSF01, FR- BLF) Install this to reduce the electromagnetic noise generated from the inverter. The noise filter is effective in the range from about 0.5 to 5 MHz.
A wire should be wound four turns at maximum. — (m) Induction motor Connect a squirrel-cage induction motor. — NOTE
