y Install the UPS in a well-ventilated indoor area, away from excess moisture, heat, dust,
ammable gas or explosives.
y Leave adequate space around all sides of the UPS for proper ventilation. Please refer to 6.2
Installation Environment.
y The UPS must be well grounded due to a possible risk of current leakage.
y It is necessary to install protective devices and 4-pole contactors when the UPS is con-
nected to the mains and bypass source. For relevant information, please refer to 6.5.1
Precautions Prior to Wiring.
y The protective devices connecting to the UPS must be installed near the UPS and must be
easily accessible for operation.
y This is a class-A product. In a domestic environment, this product may cause radio interfer-
ence, in which case, the user is required to take adequate measures.
y The UPS can be used to power computers and associated peripheral devices, such as
monitors, modems, cartridge tape drives, external hard drives, etc.
y If the UPS needs to be connected to a motor load, it must be conrmed by qualied ser-
vice personnel.
y It is strictly forbidden to connect the UPS to any loads with reection properties.
y The parallel UPSs can connect with common batteries.
y The external slits and openings in the UPS are provided for ventilation. To ensure reliable
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 In a low temperature environment (below 0°C), you must allow the UPS to adjust to room
temperature for at least one hour to avoid moisture condensing inside the UPS before us-
age.
y Do not put beverage containers on the UPS, battery cabinet or any other accessory asso-
ciated with the UPS.
y The risk of dangerous high voltage is possible when the batteries are still connected to the
UPS even though the UPS is disconnected from the mains. Do not forget to pull out the
battery cable to completely cut off the battery source.
y Do not open or mutilate the battery or batteries. The released electrolyte is harmful to the
skin and eyes and may be toxic.
y Do not dispose of the battery or batteries in a re. The batteries may explode.
y All maintenance services must be performed by qualied service personnel. Forbid open-
ing or removing the cover of the UPS to avoid high voltage electric shock.
y You must contact qualied service personnel if either of the following events occur:
1. Liquid is poured or splashed on the UPS.
2. The UPS does not run normally after this User Manual is carefully observed.
If you use the UPS in an area that generates or incurs dust, you should install a dust
lter in the UPS to ensure normal product life and function.
y
If the UPS needs to be stored prior to installation, it should be placed in a dry area. The al-
lowable storage temperature is between -15°C and +50°C.
y
Press the key ( OFF ) once and the LCD shows the following screen. If you want to
turn off the UPS, please press the key( ). Make sure the UPS is shutdown,
disconnect the UPS from the utility power, remove all equipment from the UPS, and store
the UPS in a dry and well-ventilated area at a temperature between -15°C and +50°C.
Idle batteries must be recharged fully approximately every three months if the UPS needs
to be stored for an extended period of time. The charging time must not be less than 24
hours each time.

The HPH series UPS is a three-phase four-wire online uninterruptible power supply which
provides reliable and stable sine-wave power to your electronic devices. The UPS applies the
latest design of DSP digital control technology and highest quality assembly, with an output
power factor up to unity. The efciency of the entire device can reach up to 96% in online
mode and up to 99% in ECO mode. With its outstanding features, the UPS not only provides
safe, reliable and uninterrupted power to your sensitive electronic equipment at all times, but
also produces greater electric power efciency at less cost. This HPH series UPS provides
three different rated power levels, 20kVA, 30kVA and 40kVA, for your selection.
y
During UPS transportation, some unpredictable situations might occur. It is recommended
that you inspect the UPS exterior packaging. If you notice any damage, please immedi-
ately contact the dealer from whom you purchased the unit.
y
1. Check the rating label on the top of the UPS cabinet and make sure the device No. and
capacity match what you ordered.
2. Examine if any parts are loose or damaged.
3. The UPS package contains the following items. Please check if any items are missing.

1. The balance supports have been locked on the pallet when the UPS is
shipped out of the factory. Please keep them well after unpacking. You might
use them for installation.
2. The cable connects the UPS and a Delta Mini SNMP card, Mini USB card,
Mini Relay I/O card, or Mini Modbus card. The above-mentioned cards are op-
tional. Please refer to Chapter 9: Optional Accessories.
4. If there is any damage or anything missing, please immediately contact the dealer from
whom you purchased the unit.
5. If the UPS needs to be returned, carefully repack the UPS and all of the accessories
using the original packing material that came with the unit.
y The HPH series UPS is designed for systems with medium power. It provides clean power
supply to data systems, communication systems, computer network systems, medical
treatment systems, monitoring systems, factory equipment, etc.
y The HPH series UPS utilizes all digital high frequency modulation technology, which de-
creases volume, improves reliability and prolongs service life.
y Wide AC input voltage range (full load: 173~276/ 300~477Vac; 70% load: 132~173/ 228~
300Vac) reduces frequent transfer from normal mode to battery mode to save battery con-
sumption and prolong battery life.
y Battery test in online mode and regular battery test prolong battery life.
y Automatic input frequency detection enables operation at 50Hz or 60Hz.
y You can parallel at maximum four UPS units for N+X parallel redundancy, capacity expan-
sion and reliability enhancement.
y It is convenient to set the parameters (output voltage, charging current, output frequency
and password setting, etc.) on the LCD panel.
y The operating conditions, such as load, input and output voltage, input and output frequen-
cy, battery voltage, of the device are available on LCD so that management personnel can
see them accurately and clearly.
y It can set the output voltage on LCD as: 220/ 230/ 240Vac.
y The CPU can record up to 200 entries of abnormal information of the UPS, which is helpful
in fault diagnosis for the UPS and in the improvement of the maintenance efciency.
y No-battery start-up: In case the external battery cabinet is not connected, the device can
still start up normally with normal AC.
y REPO port: Under emergency status, use a user-supplied remote control switch to discon-
nect the output immediately to prevent any danger.
y Built-in RS232 port allows monitoring and management of the UPS via the UPSentry 2012
software (http://59.125.232.140/ups/sc/index.aspx).
y Attaches optional accessories like SNMP and Mini SNMP cards for network communica-
tion.
y Other optional accessories include Mini Relay I/O, Mini USB, Mini ModBus and Mini TVSS
cards for dry contact, USB communication, ModBus communication and surge protection.
y In order to improve the efciency further, the UPS can be set to operate in ECO mode. In
case of any abnormal conditions, the UPS will transfer to online mode automatically.
yAutomatically detects and shows whether fans are operating normally.
y The fans have automatic speed regulation function. With multi-stage control over the fan
speed, it can improve the reliability and the efciency of the system, reduce the noise and
prolong the service life of the fans.
yProvides boost charge and oat charge. You can adjust the charge current from 1A to the
maximum. Each adjustment level is 0.5A. The charging mode is set according to the actual
charging current so as to keep the batteries at full charging capacity and prolong the bat-
tery life (oat charge voltage: 272Vdc; boost charge voltage: 280Vdc).

1. The UPS can still function properly without making the connections below.
2. You can use all of the communication interfaces at the same time and it will not influence
each interface’s function.
Install an SNMP card in this SMART slot to remotely control and monitor the UPS status via a net-
work. You can also insert the Relay I/O or ModBus card in this slot to let the UPS have dry contact
and ModBus communication functions respectively.
This MINI slot is for mini cards. You can install a Delta Mini SNMP, Mini Relay I/O, Mini USB, Mini
