6.10 DC Bus Voltage Measurement

Apply voltage to the Power Source.

WARNING

There are extremely dangerous voltage and power levels present inside these Power Sources. Do

not attempt to diagnose or repair unless you have had training in power electronics measurement

and troubleshooting techniques.

Once power is applied to the Power Source, there are extremely hazardous voltage and power levels present.
Do not touch any live parts.
