RI3000 User Manual V1.1 Chapter 1 -7- Use Stage Safety Grade Precautions Installation DANGER ² Consider the installation space for cooling purpose when two or more inverters are placed in the same cabinet. Wiring DANGER ² Wiring must be performed by authorized and qualified personnel. Risk of danger; ² Circuit-breaker should be installed between inverter and the mains. Risk of fire; ² Make sure the input power supply has been completely disconnected before wiring.
Failure to comply may result in personnel injury and/or equipment damage; ² Since overall leakage current of this equipment may be bigger than 3.5mA, for safety's sake, this equipment and its associated motor must be well grounded so as to avoid risk of electric shock; ² Never connect the power cables to the output terminals (U,V,W) of the AC drive. Pay attention to the marks of the wiring terminals and ensure correct wiring. Failure to comply will result in damage to the AC drive; ² Install braking resistors at terminals (P+)and (P- or PB) only. Failure to comply may result in equipment damage.
CAUTION ² Since all adjustable frequency AC drives from Our company have been subjected to hi-pot test before delivery, users are prohibited from implementing such a test on this equipment. Failure to comply may result in equipment damage. ² Signal wires should to the best of the possibility be away from main power lines. If this cannot be ensured, vertical cross-arrangement shall be implemented, otherwise interference noise to control signal may occur. ² If motor cables are longer than 100m, it is recommend- ed output AC reactor be used. Failure to comply may result in faults. Before Power-on DANGER ² Inverter shall be power-on only after the front cover is assembled.
Risk of electrical hazard. CAUTION ² Verify that the input voltage is identical to the rated voltage of product, correct wiring of input terminals R.
