EM600 High-Performance Vector Control Inverter User Manual Note: 1.Take voltage drop into consideration for selecting cable. Generally speaking, the voltage drop value calculated by the following formula shall be less than 5 V. Voltage drop = 3 *Cable Resistor (Ω/KM) * Cable Length (m) * Rated Current (A) *10 -3 2. If power cable is laid in plastic duct, it shall be one grade higher. 3. Cable shall be connected to round wiring terminals of applicable cable and terminal screw. 4. Size of grounding cable shall be the same as power cable (if less than 16 mm 2 ), or not less than 1/2 of power cable (if greater than 16 mm 2 ) and at least 16 mm 2 is a must.
3.2.8 Grounding Cable Ground terminal must be grounded. The third type grounding method specially (grounding resistance less than 10 Ω). Never share grounding cable with welder, power device or other devices. Please select grounding cable of specifications in Technical Standards of Electrical Equipment and keep it as short as possible when connecting to ground point. Do not allow grounding cable to form a circuit when two or more inverters are used. Correct and incorrect grounding methods are shown in Figure 3–11. 36 Tightening Cable Cable Terminal Model No.
