current as well as maximum charging current. Constant voltage mode, constant current mode or

floating mode can be switched automatically and smoothly.

◆Intelligent Charging Method

The series UPS adopts advanced three-stage charging method—

1st stage: high current constant current charging

to guarantee to charge back to 90%;

2nd-stage: Constant Voltage

In order to vitalize battery and make sure batteries are fully charged

3rd stage: floating mode.

With this 3-stage charging method, it extends the life of the batteries and guarantees fast charging.

◆LCD Display

With LCD plus LED displays, the user may easily get UPS status and its operational

parameters, such as input/output voltage, frequency & load%, battery % and ambient

temperature, etc...

◆Intelligent Monitoring Function

Via optional SNMP Card, you may remotely control and monitor the UPS.

◆EPO Function

The series UPS may be completely shut off when the EPO is pressed. REPO function

(Remote EPO) is also available in this series UPS.

3．Installation

3.1 Unpack checking

1. Don’t lean the UPS when moving it out from the packaging

2. Check the appearance to see if the UPS is damaged or not during the transportation, do not

switch on the UPS if any damage found. Please contact the dealer right away.

3. Check the accessories according to the packing list and contact the dealer in case of missing

parts.

3.4 Installation notes

Note: Consider for the convenience of operation and maintenance, the space in

front and back of the cabinet should be left at least 100cm and 80cm respectively when

installing the cabinet.

◆Please place the UPS in a clean, stable environment, avoid the vibration, dust, humidity,

flammable gas and liquid, corrosive. To avoid from high room temperature, a system of room

extractor fans is recommended to be installed. Optional air filters are available if the UPS operates

in a dusty environment.

◆The environment temperature around UPS should keep in a range of 0℃～40℃. If the

environment temperature exceeds 40℃, the rated load capacity should be reduced by 12％per

5℃. The max temperature can't be higher than 50℃.

◆If the UPS is dismantled under low temperature, it might be in a condensing condition. The

UPS can't be installed unless the internal and external of the equipment is fully dry. Otherwise,

there will be in danger of electric shock.

◆Batteries should be mounted in an environment where the temperature is within the required

specs. Temperature is a major factor in determining battery life and capacity. In a normal

installation, the battery temperature is maintained between 15°C and 25°C. Keep batteries away

from heat sources or main air ventilation area, etc.

WARNING!

Typical battery performance data are quoted for an operating

temperature between 20°C and 25°C. Operating it above this range will

reduce the battery life while operation below this range will reduce the

battery capacity.

◆Should the equipment not be installed immediately it must be stored in a room so as to

protect it against excessive humidity and or heat sources.

CAUTION!

An unused battery must be recharged every 6months Temporarily

connecting the UPS to a suitable AC supply mains and activating it for

the time required for recharging the batteries.

◆The highest altitude that UPS may work normally with full load is 1500 meters. The load

capacity should be reduced when this UPS is installed in place whose altitude is higher than 1500

meters, shown as the following table:

(Load coefficient equals max load in high altitude place divided by nominal power of the UPS)

Altitude(m) 1500 2000 2500 3000 3500 4000 4500 5000

Load

coefficient 100% 95% 90% 85% 80% 75% 70% 65%

◆The UPS cooling is depending on fan, so it should be kept in good air ventilation area.

There are many ventilation holes on the front and rear, so they should not be blocked by any exotic

obstacles.

3.5 External Protective Devices

For safety reasons, it is necessary to install, external circuit breaker at the input A.C. supply and

the battery. This chapter provides guidelines for qualified installers that must have the knowledge of

local wiring practices for the equipment to be installed.

◆External Battery

The UPS and its associated batteries are protected against the effect of over-current

through a DC compatible thermo-magnetic circuit-breaker (or a set of fuses) located close to

the battery.

◆UPS Output

Any external distribution board used for load distribution shall be fitted with protective

devices that may avoid the risk of UPS overloaded.

◆Over-current

Protection device shall be installed at the distribution panel of the incoming main supply. It

may identify the power cables current capacity as well as the overload capacity of the system.

3.6 Power Cables

◆The cable design shall comply with the voltages and currents provided in this section, Kindly

follow local wiring practices and take into consideration the environmental conditions (temperature

and physical support media) .

WARNING!

Upon starting. Please ensure that you are aware of the location and

operation of the external isolators which are connected to the UPS

input/bypass supply of the mains distribution panel. Check to see if

these supplies are electrically isolated. And post and necessary

warning signs to prevent any inadvertent operation.

◆For future expansion purpose, it is economical to install power cable according to the full rating

capacity initially. The diameter of cable is shown bellow：
