1-8. Circuit Protection Parts
1-8-1. Circuit Protective Element
This unit is equipped with positive-characteristic thermistors (power thermistors) as circuit protection elements.
The positive-characteristic thermistor limits the electric current flowing through the circuit as the internal resistance
increases when an excessive current flows or when the ambient temperature increases.
If the positive-characteristic thermistor works, turn off the main power of the unit and inspect the internal circuit of the
unit. After the cause of the fault is eliminated and the positive-characteristic thermistor is cooled down, turn on the main
power again. The unit works normally. It takes about one minute to cool down the positive-characteristic thermistor
after the main power is turned off.

WARNING
Fuses are essential parts for safe operation. Be sure to use the parts specified in this manual. Replacing a
fuse with an unspecified one may cause fire or electric shock.
CAUTION
If the fuse is replaced while the main power is kept on, this may cause electric shock.
Before replacing the fuse, not only turn off the POWER switch but also disconnect the cable that is connected
to the AC IN connector.
This unit is equipped with fuses. The fuses blow if overcurrent flows in the unit due to an abnormality, In that case, turn
off the power of the unit, inspect inside of the unit, and then remove the cause of the overcurrent. After that, replace the
defective parts.
