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 All wiring and equipment should be connected and installed in accordance with NFPA
70, National Electrical Code (NEC), and the applicable sections of ANSI C2, National
Electrical Safety Code (NESC). It is the responsibility of the Authority Having Jurisdic-

criteria for installation and use.
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 UPS units. For UPS parallel information and application, please con-
tact Delta service personnel.
y You can install at maximum sixteen battery modules (optional) inside the UPS cabinet.
For relevant information, please refer to 5.9 Battery Module (Optional). To extend

1 Important Safety Instructions
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 connecting to the UPS must be installed near the UPS and eas-
ily accessible for operation.
y Protective Devices:
1. For single input, please install the protective devices (1) between the main AC
source and the UPS and (2) between the connected critical loads and the UPS.
2. For dual input, please install the protective devices (1) between the main AC source
and the UPS, (2) between the bypass source and the UPS and (3) 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.
15kVA 30kVA 45kVA 60kVA
60A 125A 175A 225A
4. For selection of 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 device's must be equal to or higher than the capacity of the
UPS’s protective devices.
y If the UPS is supplied by a power source whose neutral is grounded, the backfeed
protective device installed as UPS 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 de-
vice installed as UPS input protection must be a 4-pole type.
y The recommended electrical rating of the backfeed protective device is as follows.
15kVA 30kVA 45kVA 60kVA
240V/ 60A 240V/ 125A 240V/ 175A 240V/ 225A

1.3 Usage Warnings
y Before installation, wiring and working on the UPS’s internal circuits, please completely
FXWRႇDOOSRZHUVXSSO\LQJWRWKH836LQFOXGLQJWKHLQSXWSRZHUDQGEDWWHU\SRZHU
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.
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 or any other accessory as-
sociated 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:

1-5
1 Important Safety Instructions
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 occur:
1. Liquid is poured or splashed on the UPS.
2. 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%.

y Automatic input frequency detection enables operation at 50Hz or 60Hz.
y Automatic restart:
1. The UPS will restart in online mode automatically right after the AC line resumes
following a low battery shutdown.
2. The UPS returns automatically to online mode from bypass mode after an overload
condition is cleared.
y Automatically detects whether bypass voltage is out of rating voltage (default: voltage
±10% & 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
voltage ±10% and rating frequency ±3Hz, the UPS will transfer to bypass mode; other-
