<4> Class L fuse is also approved for this rating.Wiring Fuses for Models 4A0930 and 4A1200NOTICE: If a fuse is blown or an Ground Fault Circuit Interrupter (GFCI) is tripped, check the wiring and the selection of peripheral devicesto identify the cause. Contact Yaskawa before restarting the drive or the peripheral devices if the cause cannot be identified.Install a fuse on the input side to protect drive wiring and prevent other secondary damage. Wire the fuse so that leakagecurrent in the upper controller power supply will trigger the fuse and shut off the power supply.Select the appropriate fuse from Table 3.2.Table C.9 Input Fuses for Models 4A0930 and 4A1200VoltageClass ModelSelection Input Fuse (Example)Input Voltage Current Pre-arcI2t (A2s) Model Manufacturer Rating Pre-arcI2t (A2s)Three-Phase400 VClass4A0930480 V 1500 A 140000 to3100000CS5F-1200 Fuji Electric AC500 V, 1200 A 2760004A0930 with12-pulserectificationFWH-1200A Bussman AC500 V, 1200 A –FWH-1000A Bussman AC500 V, 1000 A –4A1200480 V 1500 A 320000 to3100000CS5F-1500 Fuji Electric AC500 V, 1500 A 3510004A1200 with12-pulserectificationFWH-1600A Bussman AC500 V, 1600 A –FWH-1200A Bussman AC500 V, 1200 A –n Low Voltage Wiring for Control Circuit TerminalsWire low voltage wires with NEC Class 1 circuit conductors.
