560VDC or higher are inside the machine
Before removing any covers or commencing any testing or measurement disconnect the power source
from the mains voltage
Dangerous DC voltage may still exist after the removal of the input voltage. Machine discharges the
voltage while it is turned off, but it is always better to ensure this by measuring the voltage
Wait at least one minute for the capacitors to become discharged.
Digital multimeters (later DMM) may give different values depending the specifications they have. For
example diode measuring values may vary between the DMM models. In this manual Fluke 179 DMM is
used.
Machine has control circuitry and panel in primary side and it must be taken care of special safety
when machine is opened and connected to mains voltage.
