<4> Class L fuse is also approved for this rating.
Wiring Fuses for Models 4A0930 and 4A1200
NOTICE: If a fuse is blown or an Ground Fault Circuit Interrupter (GFCI) is tripped, check the wiring and the selection of peripheral devices
to 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 leakage
current in the upper controller power supply will trigger the fuse and shut off the power supply.
