Do not open the el. compo. box
cover for 10 minutes after the
power supply is turned off. Do not open the electrical
component box cover for 10
minutes after the power supply is
turned off.
After opening the el. compo. box,
measure (on A1P~A5P) the
points shown at the right with a
tester and confirm that the
voltage of the capacitor in the
main circuit is less than DC50V. After opening the electrical
component box, measure (on
A1P~A5P) the points shown at
the right with a tester and confirm
that the voltage of the capacitor
in the main circuit is less than
DC50V.
