EM630/TC6A Closed-Loop Vector Hoist Inverter User Manual Note: 1. Take the voltage drop into consideration for selecting cables. Generally speaking, the voltage drop value calculated by the following formula shall be less than 5V. Voltage drop = 3 *Cable Resistor (Ω/KM) * Cable Length (m) * Rated Current (A) *10 -3 2. If the power cable is laid in the plastic duct, it shall be one grade higher. 3. The cable shall be connected to the round wiring terminals of the applicable cable and the terminal screw. 4.
The size of grounding cable should be the same as the power cable if the selected power cable is less than 16mm 2 , or not less than 1/2 of the power cable if the selected power cable is greater than 16mm 2 . Anyway, at least 16mm 2 is a must. 3.2.8 Grounding Cable The ground terminal must be grounded. The third type grounding method specially (grounding resistance less than 10Ω). Never share the grounding cable with welder or power device. 38 Tightening Cable Terminal Model No.
