User Manual of EM760 High-Performance Inverter * The wires listed above refer to the outgoing wires of a single resistor. If resistors are connected in parallel, the bus should be enlarged accordingly. For models of single/three- phase 220 V conductors, cable withstand voltage should be higher than AC300V; for models of three-phase 380 V, AC450V; and for models of three-phase 660 V, AC1000V, with temperature resistance of over 105°C. 9.2 Braking unit EM760 series inverters (EM760-045-3, EM760-090-6 and above) should be used in combination with our BR100 series braking units (power range: 18.5 - 500kW). The models of our braking units are as follows.
