*2 Yaskawa recommends a fuse with a larger rated current for cyclical load applications that frequently approach 150 % overload.
◆ UL Standards Compliance for DC Power Supply Input
To comply with UL Standards, install a fuse for the DC power supply input.
Figure 5.11 shows a wiring example for a DC power supply that has two drives connected in parallel.
