3. Introduction

This On-Line series is an uninterruptible power supply incorporating
double-converter technology. It provides perfect protection specifically for computer
equipments, communication servers, and data centers.
The double-converter principle eliminates all mains power disturbances. A rectifier
converts the alternating current from the mains power to direct current. On the
basis of this DC voltage, the inverter generates an AC sinusoidal voltage, which
constantly supplies the loads. In the event of power failure, the maintenance-free
batteries power the inverter.

8. Special Function

The series UPS has some special functions, which could satisfy some special
application of user. And the functions have own features, please contact your local
distributor for further information before using the function.

8.1. ECO Function

Brief introduction of ECO function：

If ECO function is set to enable, after the UPS is turned on, the power used by the
load is directly supplied from the mains power via internal filter while the utility
power is in normal range, so the economy mode could be gained in ECO mode.
Once the mains power is loss or abnormal, the UPS would transfer to Line mode or
Battery mode and the load is supplied continuously.
The great virtue is overall high efficiency≥96% of UPS, to save power for user.
But the disadvantage is:

1) The load can’t be protected as well as in Line mode, for the load is directly
supplied from the mains;

2) The transfer time of UPS output from ECO mode to Battery mode is about
10ms.

So the function is not suitable to some sensitive loads, and the region where the
mains power is unstable.

Set the function：

The function could be enabled through the LCD setting in Bypass mode. Enter the
power strategy setting menu by following chapter of 7.3.

8.2. Converter Function

Brief introduction of Converter function：

In converter mode, the UPS would free run with fixed output frequency (50Hz or
60Hz). Once the mains power is loss or abnormal, the UPS would transfer to
Battery mode and the load is supplied continuously.
The great virtue is the output frequency is fixed, which is required by some very
sensitive loads. But the disadvantage is the load capacity of UPS should be
derated to 60% in converter mode.

Set the function：

The function could be enabled through the LCD setting in Bypass mode. Enter the

30

power strategy setting menu by following chapter of 7.3.

8.3. Parallel Function

Brief introduction of the redundancy：

N+X is currently the most reliable power supply structure. N represents the
minimum UPS number that the total load needs, X represents the redundant UPS
number, i.e. the fault UPS number that the system can handle simultaneously.
When the X is larger, the reliability of the power system is higher. For occasions
where reliability is highly depended on, N+X is the optimal mode.
As long as the UPS is equipped with parallel cables, up to 4 UPS can be connected
in parallel to realize output power sharing and power redundancy.

How to install a new parallel UPS system:

1) Before installing a new parallel UPS system, user need to prepare input and
output wires, input and output breaker, main maintenance bypass switch.

2) Remove the cover plate of the parallel port on the UPS, connect each UPS
one by one with the parallel cable, and re-screw the parallel port cover which is
supplied in the accessories.

Fig.8-1 Parallel cable connect diagram

3) Strictly follow the chapter of 6.1, the wiring requirement of single UPS to
perform the wiring of each UPS.

31

4) Connect the output wires of each UPS to an output breaker panel, and connect
each output breaker to a main output breaker and then to the loads.

5) CAUTION: Each UPS needs an independent battery pack.

6) Please refer to the wiring diagram in the following diagram.

7) The distance between the UPS in parallel and the breaker panel is required to
be less than 20 meters. The difference between the wires of input and output
of the UPS is required to be less than 20%.

8) Do not switch on the output breaker of each UPS, switch on the input breaker
of the each UPS, the UPS should work in bypass with output, observe their
display to check if there are any warning or fault information, measure the
output voltage of each UPS separately to check if the voltage difference
between them is less than 1V. If the difference is more than 1V, check the
wiring.

9) Press the button of one UPS, each UPS would start to turn on, all the
UPS would transfer to the Line mode together. Measure the output voltage of
each UPS separately to check if the voltage difference between them is less

than 0.5V. If the difference is more than 0.5V, the UPS need to be regulated.

10) Press the button of one UPS, each UPS would start to turn off and
transfer to the Bypass mode, switch on the output breaker of each UPS to
parallel all the output of UPS together.

11) Press the button of one UPS, each UPS would start to turn on , after
turning on, the UPS should work parallel in the Line mod

How to join a new UPS to a parallel system:

1) First the parallel system must be installed one main maintenance bypass
