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.
WARNING! Electrical Shock Hazard. Do not ground the main circuit bus. Incorrect wiring can cause serious injury or death.
