1. The inrush current is given for a cold start at room temperature for AC Pow-
er Supply Units and for a cold start for DC Power Supply Units. The inrush
control circuit uses a thermistor element with a low-temperature current
control characteristic. If the ambient temperature is high or the NSJ Con-
troller is hot-started, the thermistor will not be sufficiently cool, and the in-
rush currents given in the table may be exceeded by up to twice the given
values. When selecting fuses or breakers for external circuits, allow suffi-
cient margin in shut-off performance.
A delay circuit that charges a capacitor is used to limit the inrush current in
DC Power Supply Units. If a hot start is performed when the power supply
has been OFF only a short period of time, the capacitor will still be charged
and the inrush current specified above will be exceeded by up to approxi-
mately twice the specified value.
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 in the NSJ Controller.
3. Change the applied voltage gradually using the adjuster on the Tester. If
the full dielectric strength voltage is applied or turned OFF using the switch
on the Tester, the generated impulse voltage may damage the Power Sup-
ply Unit.
4. Maintain an ambient storage temperature of − 25 to 30 ° C and an ambient
humidity of 25% to 70% when storing the Unit for longer than 3 months to
keep the replacement notification function in optimum working condition.
5. CJ1W-PD022 is not insulated between the primary DC power and second-
ary DC power.
