1.1 Installation Warnings
y This is a three-phase four-wire on-line uninterruptible power supply (hereafter referred
to as 'UPS'). It can be used for commercial and industrial applications.
y Install the UPS in a well-ventilated indoor area, away from excess moisture, heat, dust,
ÀDPPDEOHJDVRUH[SORVLYHV
y Leave adequate space around all sides of the UPS for proper ventilation and mainte-
nance. Please refer to 5.2 Installation Environment.
y Only authorized Delta engineers or service personnel can perform installation and
maintenance. If you want to install the UPS by yourself, please install it under the su-
pervision of authorized Delta engineers or service personnel.
y Follow the IEC 60364-4-42 standard to install the UPS.
1.2 Connection Warnings
y Before applying electrical power to the UPS, make sure the UPS is grounded to avoid a
possible risk of current leakage.
y You can parallel at maximum eight UPS units.
y The UPS must be connected with an external battery cabinet (user-supplied, handled

net Connection Warnings for relevant information.
y The installation of protective devices is highly recommended when the UPS is connect-
ed to power sources and critical loads.
y The protective devices connected to the UPS must be installed near the UPS and easily
accessible for operation.
y Protective Devices:
1. For single input, please install (1) a protective device between the main AC source
and the UPS and (2) a protective device between the connected critical loads and
the UPS.
2. For dual input, please install (1) a protective device between the main AC source
and the UPS, (2) a protective device between the bypass source and the UPS and (3)
a protective device between the connected critical loads and the UPS.
3. Each protective device could be a breaker or a fuse. For the protective device’s
rating current, please refer to the table below.

4. Each protective device should have the functions of over current protection, short
circuit protection, insulating protection and shunt trip feature. Please refer to the

10kA 10kA 12.12kA 15.15kA 18.18kA
5. When selecting the protective devices, please take each power cable’s current
capacity and the system’s overload capacity (please refer to Appendix 1: Technical
Specifications) into consideration. Besides, the short-circuit capacity of the
upstream protective devices must be equal to or larger than the capacity of the
UPS’s input protective devices.
6. When the UPS has abnormalities and input short-circuit current reaches 20kA, the
UPS’s internal semi-conductor fast-acting fuses need 8 ~ 10ms to be blown. Thus,
the upstream protective devices’ reaction time should be more than 10ms so that

system breakdown and let the UPS transfer to bypass mode.
7. If the UPS is supplied by a power source whose neutral is grounded, the backfeed
protective device installed as the UPS’s input protection must be a 3-pole type. If
the UPS is supplied by a power source whose neutral is not grounded, the backfeed
protective device installed as the UPS’s input protection must be a 4-pole type.
8. The recommended electrical rating of the backfeed protective device is as follows.
200kVA 300kVA 400kVA 500kVA 600kVA
690V/ 400A 690V/ 600A 690V/ 800A 690V/ 1000A 690V/ 1250A
1.3 Usage Warnings
y Before installation, wiring and working on the UPS’s internal circuits, please completely

y The UPS is specifically designed for information technology equipment and used to
power computers, servers, and associated peripheral devices. If you want to connect
any capacitive loads or non-linear loads (that have serious surge current) to the UPS,
it needs to be de-rated according to on-site applications. For such special applications,
please contact Delta service personnel for the accurate UPS sizing. The UPS is not
suitable for connecting with any asymmetrical loads.
y The external slits and openings in the UPS are provided for ventilation. To ensure reli-
able operation of the UPS and to protect the UPS from overheating, these slits and
openings must not be blocked or covered. Do not insert any object into the slits and
openings that may hinder ventilation.

Modulon DPH Series
y Before applying electrical power to the UPS, you must allow the UPS to adjust to room
temperature (20°C ~ 25°C) for at least one hour to avoid moisture condensing inside
the UPS.
y Do not put beverages on the UPS, external battery cabinet(s) or any other accessory
associated with the UPS.
y Do not open or remove the covers or panels of the UPS to avoid high voltage electric
shock. Only authorized Delta engineers or service personnel can do so for installation
or maintenance. If you want to open or remove the covers or panels, do it only under
the supervision of authorized Delta engineers or service personnel.
y It is strictly forbidden to connect the UPS to any regenerative loads.
y The risk of dangerous high voltage is possible when batteries are still connected to the
UPS even though the UPS is disconnected from the power sources. Before mainte-

y Do not open or damage the battery or batteries. The released electrolyte is harmful to
the skin and eyes and may be toxic.
y The UPS is electronic equipment that runs 24 hours continuously. To ensure its normal
lifetime, regular maintenance of the UPS and batteries is of vital importance and neces-
sary.
y Some components like batteries, power capacitors, and fans will become worn-out due
to long-term usage, and this will increase the risk of UPS failure. To replace and main-
tain the components, please contact Delta service personnel.
y A battery can present a risk of electric shock and high short-circuit current. The follow-
ing precautions should be observed before replacement of batteries:
1. Remove watches, rings, or other metal objects.
2. Use tools with insulated handles.
3. Wear insulating gloves and boots.
4. Do not lay tools or metal parts on the top of batteries.
5. Disconnect the charging source prior to connecting or disconnecting the batteries’
terminals.
y You must contact Delta customer service if either of the following events occurs:
1. Liquid is poured or splashed on the UPS.
2. The UPS is deformed.

3. Any conductive powders or metals enter into the UPS.
4. The UPS does not run normally after carefully following the instructions in this User
Manual.
1.4 Storage Warnings
y Use the original packing material to pack the UPS to prevent any possible damage from
rodents.
y If the UPS needs to be stored prior to installation, it should be placed in a dry indoor
area. The allowable storage temperature is below 70°C and relative humidity is below
95%.

1. The UPS will restart in normal mode automatically right after the AC line resumes
following a low battery shutdown.
2. The UPS returns automatically to normal mode from bypass mode after an overload
condition is cleared.
y Automatically detects whether bypass voltage is out of rating voltage (default: voltage
±15% & frequency ±3Hz). If yes, the UPS will stop supplying power to the critical loads
to protect your electronic equipment.
y Supports ECO mode: when input voltage and frequency are within the range of rating

2 Introduction
y Battery start-up function even when there is no AC input.
y AC start-up function even when the UPS is not connected to the batteries.
WARNING:
Please note that when the UPS is not connected to the batteries, it will not
protect your equipment if the utility power is lost.
y Connects at maximum eight external battery cabinets (optional) to extend backup time.
y Sets up schedulable battery test and battery replacement alarm.
y Battery temperature monitoring and compensation.
y Optional battery management system (BMS) allows measurement of every battery’s
voltage.
y Smart battery charger design allows auto-charging or manual charging to shorten
charging time.
y Provides diversified communication interfaces and a SMART slot. Please refer to 4.
Communication Interfaces.
y Built-in RS-232 port and USB port located on the communication interfaces allow moni-
toring and management of the UPS. For relevant location and information, please refer
to Figure 4-14 and Page 4-12.
y Built-in SNMP card and MODBUS card located at the rear of the touch panel provide
network communication and MODBUS communication respectively. Besides, the SNMP
card allows remote monitoring, management and event log download of the UPS. For
relevant location and information, please refer to Figure 4-17 and Page 4-14.

y Built-in SRAM records at maximum 10,000 event logs.
y 10-inch graphic and color touch panel enables users to easily operate the UPS and un-
derstand the UPS status.
y Fan speed auto adjustment prolongs fan life and reduces noise when the critical loads
decrease. Moreover, fan failure detection circuit is established.
y State-of-the-art microprocessor technology performs self-detection and monitors fan
speed in real time, which provides complete and detailed operating status of the UPS.
