Coordinator Module Section 2-3
Note (1) The inrush current is given for a cold start at room temperature with an
AC power supply. The AC inrush control circuit uses a thermistor element
with a low-temperature current control characteristic. If the ambient tem-
perature is high or the FQM1 is hot-started, the thermistor will not be suf-
ficiently cool, and the inrush currents given in the table may be exceeded
by up to twice the given values. When selecting fuses or breakers for ex-
ternal circuits, allow sufficient margin in shut-off performance. If the
FQM1 is hot-started, the capacitor will not be discharged, and the inrush
currents given in the table may be exceeded by up to twice the given val-
ues.
(2) Disconnect the Power Supply Unit's LG terminal from the GR terminal
when testing insulation and dielectric strength. Testing the insulation and
dielectric strength with the LG terminal and the GR terminals connected
will damage internal circuits.
