Before removal of clip-off sections Wiring Guide (e.g. <strong>EQ7</strong>-4025-C) After removal of clip-off sections (8) In some types of inverters, the wires from the main circuit terminal block cannot be routed straight into the terminal. Route such wires as shown below so that the front cover can be reinstalled. (9) For inverters of 900 and 1000 HP, two L2/S input terminals are arranged vertically to the terminal block. When connecting wires to these terminals, use the bolts, washers and nuts that come with the inverter, as shown below. 2-9
• When wiring the inverter to the power source, insert a recommended molded case circuit breaker (MCCB) or residual-current-operated protective device (RCD)/earth leakage circuit breaker (ELCB) (with overcurrent protection) in the path of each pair of power lines to inverters. Use the recommended devices within the recommended current capacity. • Be sure to use wires in the specified size. • Tighten terminals with specified torque. Otherwise, a fire could occur. • When there is more than one combination of an inverter and motor, do not use a multiconductor cable for the purpose of running the leads together. • Do not connect a surge killer to the inverter's output (secondary) circuit. Doing so could cause a fire. • Ground the inverter in compliance with the national or local electric code. • Be sure to ground the inverter's grounding terminals G. Otherwise, an electric shock or fire could occur. • Qualified electricians should carry out wiring. • Be sure to perform wiring after turning the power OFF. Otherwise, electric shock could occur. • Be sure to perform wiring after installing the inverter unit. Otherwise, electric shock or injuries could occur. • Ensure that the number of input phases and the rated voltage of the product match the number of phases and the voltage of the AC power supply to which the product is to be connected. Otherwise, a fire or an accident could occur. • Do not connect the power source wires to inverter output terminals (U, V, and W). Doing so could cause fire or an accident. 2-10
