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.
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 by
the "Electric Facilities Technical Standards Type D (100Ωor less)" or a higher standard.
Warning
This contains information to avoid risks in equipment handling that could
result in loss of life or bodily injury (e.g., electric shock).
Caution
This contains information to avoid damage to the equipment in equipment
handling.
Other symbol
Chassis
This indicates that the terminal (or external conductor for a connector) is connected to
the chassis.
Request about disposal
For environmental preservation, pay attention to the followings when you dispose of this product.
The backlight of the LCD contains mercury.
This product shall be disposed of through an appropriate industrial waste disposer.

1.1 Overview
The DP series offers a compact, lightweight, and highly-efficient power system, ranging from
single-phase 1.5 kVA to three-phase 36 kVA at a maximum. It also provides various interfaces such
as the external control input/output, communication interface, and remote controller (some of them
are optional) to address a wide variety of usage. You can configure several products of same
single-phase model to participate in a single-phase three-wire system or three-phase four-wire
system by using a System Cable (optional).
The AC output of DP series 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 120 Arms continuous (single-phase 12 kVA, 100 V range), and if you use a
capacitor input type rectified load, you can output a peak value of 480 Apk at a maximum
(single-phase 12 kVA, 100 V range, crest factor of 4).
1.2 Series Line-up and Polyphase System Configuration
In the DP series, multiple models (single-phase model, polyphase model) are available with various
combinations of output capacity and output phase mode. The lineups of single-phase model and
polyphase model are listed in Table 1-1.
The DP series also offers the Multi-phase model which can switch the output phase mode
(single-phase two-wire, single-phase three-wire, or three-phase four-wire) on a cabinet. When you
set the "phase mode setting switch" of the Multi-phase model and then turn on the power, the model
operates as single-phase model or polyphase model as shown in Table 1-2. The operation
specification, performance specification, and manipulation method of the Multi-phase model follow
those of the single-phase model and polyphase model of the DP series shown in Table 1-2.
The model naming system of the DP series is shown in Figure 1–1.
For the single-phase model, you can connect two or three products of the same model using an
optional System Cable to allow single-phase three-wire output or three-phase four-wire output,
respectively (polyphase system). The polyphase system configurations are listed in Table 1-3.
