Control board measurements
WARNING
All service to this piece of equipment must be
performed by qualified personnel.
CAUTION
The control board (#49120/407415) is electrically referenced
to high voltage, not earth or chassis ground. Extreme care
must be used when taking measurements on the control
board. Any AC powered instruments must be ground
isolated prior to taking measurements. A ground isolated
instrument case will be at the high voltage line potential.
Measurement procedure
Verify the L–N for each phase is ±3% of the nominal
voltage. If the voltage measurement is out of range,
consult factory.
