Install DC Bus Fuse
Step 9
Shut the power off to the inverter drive and lock it out if possible. Allow the DC
bus to discharge. When the charge LED has gone out, use a DC voltmeter to
check the DC bus voltage. When the DC bus voltage reaches 10 VDC, it is
safe to work inside the unit. Remove the resistor and re-install the DC bus
fuse.
