Replacing fuse
WARNING
• If the fuses are replaced while power is supplied, there is
a serious risk of electric shock. Before replacing the
fuses, set the power switch to OFF and remove the
power cord from the power outlet.
• If power is supplied without protective grounding, there
is a risk of accidental electric shock. In addition, if the
AC power supply voltage is unsuitable, there is a risk of
the internal circuits of the MS8608A/MS8609A being
damaged by the abnormal voltage. Before supplying
power again after changing the fuses, check that the pro-
tective grounding described previously is still con-
nected, and check that the AC power supply voltage is
suitable. Then, set the power switch to ON.
CAUTION
When there are no supplied spare fuses, the replacement
fuses must have the same rated voltage and current as the
fuses in the fuse holders.
• If the replacement fuses are not of the same type, they
may not fit correctly, there may be a faulty connection, or
the time taken to for the fuses to blow may be too long.
• When an abnormality occurs again, if the voltage and
current rating of the fuses is incorrect, the fuses may not
blow with a consequent risk of damage to the equipment
by fire.
