warnings in other chapters of the manual may impair the protective functions
provided by the instrument.
NGI shall not be liable for the results caused by the neglect of those instructions.
2.1 Safety Notes
Confirm the AC input voltage before supplying power.
Reliable grounding: Before operation, the instrument must be reliably grounded
to avoid the electric shock.
Confirm the fuse: Ensure to have installed the fuse correctly.
Do not open the chassis: The operator cannot open the instrument chassis.
Non-professional operators are not allowed to maintain or adjust it.
Do not operate under hazardous conditions: Do not operate the instrument
under flammable or explosive conditions.
Confirm the working range: Make sure the DUT is within N3410’s rated range.

2.3 Warnings
If the output floating voltage of the power supply is greater than ±60VDC, operator
will be exposed to the risk of electric shock at the terminal. When using an
non-insulated metal short-circuit bar to connect positive(+) output terminal to
positive(+) polarity of DUT, and connect negative(-) output terminal to negative(-)
polarity of DUT, please make sure the output floating voltage should be not greater
than ±60VDC.
+
-
The maximum floating voltage to ground is 60VDC. ±
(Using non insulated short circuit conductor)- -
If insulators are used instead of non-insulated metal short-circuit bars, or these
short-circuit bars are removed from the terminals so that no operator can touch the
non-insulated output conductors, the maximum output floating voltage can reach
±240VDC. The insulation of all wires at the operation site must meet the present
voltage requirements.

When the output voltage/current is higher than OVP/OCP set value, N3410 will shut
off output, and alarm OVP/OCP will be displayed on the screen. At this time, users
can press for three times continuously to clear the protection.
When overvoltage/overcurrent protection occurs, please also check whether
OVP/OCP setting value is lower than output voltage/current. If this is not the case,

Acive
Load
Figure 11 Active load wiring diagram
Note: When overvoltage/overcurrent occurs, the protection circuit inside N3410
will shut off output. If an active load such as a battery is connected to N3410
output interface, when overvoltage/overcurrent occurs, the current from the active
load such as the battery is poured into the internal circuit of N3410, which will
damage N3410. To avoid this situation, users can connect a diode in series with the
output interface, as shown in the figure below.
