return connectors for each of the eight circuit breakers within the 20A/10A circuit
breaker panel. Record and note any readings which are out of range.
Is the voltage between -40 and -60 V dc at each position?
NO Go to Step 4.
YES Go to Step 3b.

panel to the On position.
3. Measure for -40 to -60 V DC between the -48 V DC supply and positive ground
return connectors for each of the eight circuit breakers within the 15A circuit
breaker panel. Record and note any readings which are out of range.
