Ensure you obey the instructions in this instruction manual.
This instruction manual contains instructions for safe operation and use of this product.
Before using the product, please read this manual first.
All the warning items contained in this instruction manual are intended for preventing risks that may
lead to serious accidents. Ensure to obey them.
Ensure to ground.
Ensure to connect the protective conductor terminal of the power input terminal of this product to an
earth ground so that ground resistance is 100 or less. If the product is not certainly grounded, an
electric shock might occur.
To prevent electric shock, ensure that the protective grounding conductor is connected before you
connect a cable to the power input terminals L1, L2 and L3.
For grounding, use a power cable of sufficient ampacity for the maximum input current (see Table
2-4).
Check the power supply voltage.
This product operates on the power supply voltage specified in "2.4 Grounding and Power
Connections". Before connecting the product to a power supply, make sure that the voltage of
distribution board conforms to the power supply voltage rating of the product.
If you notice anything strange
If this product produces smoke, unusual odor, or strange sound, immediately cut the power to the
product and stop using it.
Should you encounter any anomaly like above, immediately contact us or our agent. Never use it
until the repair is completed.
Do not use in a gaseous atmosphere.
This may pose a risk of explosion or other.
Do not remove the cover.
This product has high-voltage portions inside. Never remove the cover.
When inspection into the inside of the product is needed, never allow anybody to touch the innards
except our certified service engineers.

DP240S/DP360S iii
Do not modify the product.
Never modify the product. Modification to the product may pose a new risk. We may refuse the
repair of a modified product at fault.
Prevention of electric shock by output voltage
The maximum output of this product is ± 440 V. Be careful to avoid electric shock. Directly
touching the output or changing the cable connection while the output is on may cause electric
shock.
This product weights over 18 kg.
Do not carry it alone, or you may suffer physical injury.
Do not expose this product to water.
When this product is used in wet condition, it may cause an electric shock and a fire. If this product
is exposed to water, cut the power at the distribution board immediately, and contact NF Corporation
or one of our representatives.
If lightning occurs, power off this product and cut the power at the distribution board.
A lightning may cause an electric shock, a fire and a failure.
Safety symbols
The following shows the general definitions of the safety symbols used on the product main unit and
in the instruction manual.
Refer to the instruction manual
This notifies the user of potential hazards and indicates that he/she must refer to the
instruction manual.
Electric shock hazard
This indicates that an electric shock may occur under specific conditions.
Protection conductor terminal
This indicates that the terminal needs to be grounded in order to prevent electric shock
accidents.
Before operating the equipment, ensure to connect this terminal to an earth ground so
that ground resistance is 100 or less.
Warning
Equipment handling could result in death or serious injury. This symbol
contains information to avoid such risk.
Caution
Equipment handling could result in minor or moderate injury, or property
damage. This symbol contains information to avoid such risk.

1.1 Overview
Programmable AC power source DP240S / DP360S are 24 kVA / 36 kVA single phase AC
stabilized power source which inherit the performance and function of DP series. It is powered from
three-phase 200 V AC. It provides various interfaces such as the external control input/output,
communication interface, and remote controller to address a wide variety of usage. You can
configure several products of the same model to participate in a single-phase three-wire system (max
48 kVA / 72 kVA) or three-phase four-wire system (max 72 kVA / 108 kVA) by using a System
Cable (optional).
The AC output of DP240S/DP360S ranges from 0 to 310 V for voltage (phase voltage) and 1 to 550
Hz for frequency, and the DC voltage output ranges from 440 V to +440 V. The maximum output
current (phase current) is 240 Arms/360 Arms continuous (100 V range), and if you use a capacitor
input type rectified load, you can output a peak value of 960 Apk/1080 Apk at a maximum (100 V
range, crest factor of 4).
