5.NOTE FOR REPAIRING SERVICE
Rated allowable power
This model's power circuit is partly different in the GND. The
No indication: 1/16 [W]
difference of the GND is shown by the LIVE : ( ) side GND and the
Others: As specified
ISOLATED(NEUTRAL ) : ( ) side GND. Therefore, care must be
Typetaken for the following points.
No indication: Carbon resistor(1)Do not touch the LIVE side GND or the LIVE side GND and the
OMR: Oxide metal film resistor ISOLATED(NEUTRAL ) side GND simultaneously. if the above
caution is not respected, an electric shock may be caused.
MFR: Metal film resistor
Therefore, make sure that the power cord is surely removed from
MPR: Metal plate resistor
the receptacle when, for example, the chassis is pulled out.
UNFR: Uninflammable resistor
(2)Do not short between the LIVE side GND and ISOLATED(NEUTRAL )
FR: Fusible resistor
side GND or never measure with a measuring apparatus measure
Composition resistor 1/2 [W] is specified as 1/2S or Comp. with a measuring apparatus ( oscilloscope, etc.) the LIVE side GND
and ISOLATED(NEUTRAL ) side GND at the same time.
(2)Capacitors
If the above precaution is not respected, a fuse or any parts will be broken.
Capacitance value
Since the circuit diagram is a standard one, the circuit and1 or higher: [pF]
circuit constants may be subject to change for improvement
less than 1: [?F]
without any notice.
Withstand voltage
No indication: DC50[V]NOTE
Due improvement in performance, some part numbers show
Others: DC withstand voltage [V]
in the circuit diagram may not agree with those indicated in
AC indicated: AC withstand voltage [V]the part list.
Electrolytic CapacitorsWhen ordering parts, please use the numbers that appear
47/50[Example]: Capacitance value [?F]/withstand voltage[V]in the Parts List.
