1.1 Safety Instructions
RISK OF ELECTRIC SHOCK!
y
Do not open or remove the cover of the UPS to avoid high voltage electric shock. Only
authorized Delta engineers or service personnel can do so for installation or mainte-
nance. If you want to open or remove the cover, do it only under the supervision of au-
thorized Delta engineers or service personnel.
y
The risk of dangerous high voltage is possible when batteries are still connected to the
UPS even though the UPS is disconnected from AC power sources. Before mainte-
nance, do not forget to cut off the battery source.
yA 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.
yBefore applying electrical power to the UPS, make sure the UPS is grounded to avoid a
possible risk of current leakage.
yBefore working on the UPS’s internal circuits, cut off the input power and the battery
source.

1Important Safety Instructions
WARNING!
yFollow the IEC 60364-4-42 standard to install the UPS.
yConnect the UPS’s output to either critical loads or rack-mount PDCs (optional). Please
only choose one application. You can install at maximum two rack-mount PDCs in one
UPS.
yIf the UPS’s output connects to the rack-mount PDC (optional; at maximum two), please
refer to the rack-mount PDC’s user manual for relevant information about the rack-
mount PDC’s installation, wiring and operation.
yLeave adequate space around all sides of the UPS for proper ventilation and mainte-
nance. Please refer to 5.2 Installation Environment.
yThe installation of protective devices is highly recommended when the UPS is connect-
ed to power sources and critical loads.
yThe protective devices connecting to the UPS must be installed near the UPS and must
be easily accessible for operation.
yThe 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.
yTo protect the UPS from overheating, wiring must not block or cover any fans of the
Power Module (optional; at maximum six) and the rack-mount PDC (optional; at maxi-
mum two).
yIf the UPS is supplied by a source whose neutral is grounded, the protective device
installed as UPS input protection must be a 3-pole type. If the UPS is supplied by a
source whose neutral is not grounded, the protective device installed as UPS input pro-
tection must be a 4-pole type.
yDo not put beverages on the UPS, external battery cabinet or any other accessory as-
sociated with the UPS.
yBefore applying power to the UPS, you must allow it to adjust to room temperature (20°C
~ 25°C) for at least one hour to avoid moisture condensing inside the UPS.
yThe UPS is electrical 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.
ySome 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 customer service department.

1-4
Modulon DPH Series 25-150 kW
yThe UPS can be used to power computers and associated peripheral devices, such as
monitors, modems, cartridge tape drives, external hard drives, etc. If you want to con-
nect inductive or capacitive loads to the UPS, it needs derating. Please contact Delta
service personnel for derating information.
yIf the UPS needs to be stored prior to installation, it should be placed in a dry indoor area.
The allowable storage temperature is below 40°C and relative humidity is below 90%.

ment (e.g. forklift) to carefully move the UPS from pallet to ground. Please pay attention
to the movement of UPS’s casters to avoid accidents.
yThe casters are designed to move on level ground. Do not move the UPS on an uneven
surface. This might cause damage to the casters or tip the UPS which could damage
the unit.

Modulon DPH Series 25-150 kW
2.1 General Overview
The DPH series UPS is a three-phase, four-wire online UPS designed for applications in
large-scale data centers, factories and other facilities. With its innovative IGBT (Insulated
Gate Bipolar Transistor) architecture, the UPS provides high quality, low noise, pure and
uninterrupted power supply.
Its modular and hot-swappable design provides a highly cost-effective solution to your
power requirements. The number of Power Modules installed in the UPS can be customized
based on your needs. As your power demands arise, you can easily increase system
capacity by adding more Power Modules to the UPS. This design also makes module
maintenance quick, easy, and non-interruptive to the operation of the system.
The Hot Standby Redundancy, Common Battery and ECO Modes can be used to enhance

2.4 Exterior
On the front of the UPS, you can see a control panel and a door lock. Inside the cabinet,
there are two rack-mount PDC slots, a Control Module (including communication interfaces),
an STS Module, four breakers, and six Power Module slots. At the back of the UPS (after
opening the rear doors and removing the panels shown in Figure 5-4), you can see the
UPS’s wiring terminal block. If you install the rack-mount PDC (optional; at maximum two)
in the UPS, you can also see the rack-mount PDC’s wiring terminal block. Please refer to
the rack-mount PDC’s user manual for relevant information about the rack-mount PDC’s
