1-16. Circuit-Protection Part List

Circuit Protection Element
This unit is equipped with the positive characteristics
thermister(s) (power thermister) as the circuit protection
element. The positive characteristics thermister limits the
electric current flowing through the circuit as the internal
resistance increases when an exces-sive current flows or
when the ambient temperature increases.
If the positive characteristics thermister works, turn off the
main power of the unit and inspect the internal circuit of
this unit. After the cause of the fault is removed, turn on
the main power again. The unit works normally.
It takes about one minute to cool down the positive
characteristics thermister after the main power is turned
off.
