7.3 Verifying AC Mains and DC Power Supply
This section describes how to verify that the RBS has the correct incoming AC
mains and, where applicable, DC power.
Danger!
Electric shock risk. Avoid both direct and indirect contact with parts connected
to mains power as this is likely to be fatal. Switch off the mains power before
starting work.
