Important Safety Instruction
Components indicated by a mark have special significance to product safety. Please use the parts specified by
the manufacturer for replacement.
Low and high voltage caution
The power circuit board comprises a circuit unit using a separate power supply and isolated from the ground.
The circuit is divided into
high voltage and low voltage circuits. Please adopt the following precautions.
The schematic diagram is the final version before production. It may be revised without another notice.
Precautions
Do not touch the part on
hot side or both parts on the hot and cold sides at the same time.
Do not shorten the circuit between
hot and cold sides. Otherwise, the fuse will disconnect and parts will be damaged.
Do not connect instruments such as an oscilloscope on both
hot and cold sides to prevent the fuse from being melt.
The measured circuit instrument should be grounded.
When the core is removed, remove the power cable from the socket.
When you book the part, check the maintenance code of the part on the parts list.

Caution
Components indicated by a mark in this schematic diagram have
the special significance in the safety. It is therefore, particularly
recommended that the replacement of those parts must be made
by exactly the same parts. Unauthorized substitutions may result
in fire or accident.
This project is isolated from AC line by using the internal converter
transformer.
Please pay attention to the following notes in servicing.
1. Do not touch the part on the primary circuit or both the primary
and secondary circuits at the same time.
2. Do not shorten the circuit between the primary and secondary
sides.
3. The grounding lead must be connected to the ground of the
same circuit when measuring the voltage and waveform.
