These schematic diagrams are the latest at time of printing and are subject to change without notice.
REMARKS
a. Do not touch the hot part, or the hot and cold parts at the same time, as you are liable to a shock hazard.
b. Do not short circuit the hot and cold circuits as electrical components may be damaged.
c.
Do not connect an instrument, such as an oscilloscope, to the hot and cold circuits simultaneously as this may cause
fuse failure. Connect the earth of the instruments to the earth connection of the circuit being measured.
fuse failure. Connect the earth of the instruments to the earth connection of the circuit being measured.
d. Make sure to disconnect the power plug before removing the chassis.
NOTE
1. The Power Supply Circuit contains a circuit area, which uses a separate power supply to isolate the earth connection.
The circuit is defined by HOT and COLD indications in the schematic diagram. All circuits, except the Power Circuit, are
COLD.
