Safety Instructions 4. Maintenance, inspection, and parts replacement ! WARNING - Before inspecting the inverter, be sure to turn off the power supply and wait for 10 minutes or more. Otherwise, you run the risk of electric shock. (Before inspection, confirm that the Charge lamp on the inverter is off and the DC voltage between terminals P and N is 45 V or less.) - Commit only a designated person to maintenance, inspection, and the replacement of parts. (Be sure to remove wristwatches and metal accessories, e.g., bracelets, before maintenance and inspection work and to use insulated tools for the work.) Otherwise, you run the risk of electric shock and injury. 5. Others ! WARNING - Never modify the inverter. Otherwise, you run the risk of electric shock and injury. ! CAUTION - Do not discard the inverter with household waste. Contact an industrial waste management company in your area who can treat industrial waste without polluting the environment. iv
Safety Instructions Precautions Concerning Electromagnetic Compatibility (EMC) The SJ700 series inverter conforms to the requirements of Electromagnetic Compatibility (EMC) Directive (2004/108/EC). However, when using the inverter in Europe, you must comply with the following specifications and requirements to meet the EMC Directive and other standards in Europe: ! WARNING: This equipment must be installed, adjusted, and maintained by qualified engineers who have expert knowledge of electric work, inverter operation, and the hazardous circumstances that can occur. Otherwise, personal injury may result. 1. Power supply requirements a. Voltage fluctuation must be -15% to +10% or less. b. Voltage imbalance must be ±3% or less. c. Frequency variation must be ±4% or less. d. Total harmonic distortion (THD) of voltage must be ±10% or less. 2. Installation requirement a. A special filter intended for the SJ700 series inverter must be installed. 3. Wiring requirements a. A shielded wire (screened cable) must be used for motor wiring, and the length of the cable must be according to the following table (Table 1). b. The carrier frequency must be set according to the following table to meet an EMC requirement (Table 1). c. The main circuit wiring must be separated from the control circuit wiring. 4. Environmental requirements (to be met when a filter is used) a. Ambient temperature must be within the range -10°C to +40°C. b. Relative humidity must be within the range 20% to 90% (non-condensing). c. Vibrations must be 5.9 m/s 2 (0.6 G) (10 to 55 Hz) or less. (0.4-22kW) 2.94 m/s 2 (0.3 G) (10 to 55Hz) or less. (30 to 150kW) d. The inverter must be installed indoors (not exposed to corrosive gases and dust) at an altitude of 1,000 m or less. cable carrier model cat. length(m) frequency(kHz) SJ700-004L C3 5 2.5 model cat. cable length(m) carrier frequency(kHz) SJ700-007L C3 5 2.5 SJ700-007H C3 5 2.5 SJ700-015L C3 5 2.5 SJ700-015H C3 5 2.5 SJ700-022L C3 5 2.5 SJ700-022H C3 5 2.5 SJ700-037L C3 5 2.5 SJ700-037H SJ700-040H C3 5 2.5 SJ700-055L C3 1 1 SJ700-055H C3 1 2.5 SJ700-075L C3 1 1 SJ700-075H C3 1 2.5 SJ700-110L C3 1 1 SJ700-110H C3 1 2.5 SJ700-150L C3 1 1 SJ700-150H C3 1 2.5 SJ700-185L C3 1 1 SJ700-185H C3 1 2.5 v
