2 Overview

High cost performance

Adopt many kinds of power conversations and high frequency PWM technologies, which is with
high efficiency, small volume, light weight, improves the running reliability and reduces cost.

Perfect protection

Equipped with the functions, such as output over-voltage protection, battery under-voltage protection,
input over-voltage protection, triple over-current protection, etc. and solve the problems of the high
frequency UPS, such as poor adaptability in the power grid and weak anti-impact ability.

Low mains input voltage

Adopt the independent rapid detection technology. When the mains input voltage is 120V, which is
the lower limit, the battery still doesn't discharge. Therefore, in the mains mode, all output power gets
from the power grid, which is to ensure the battery is still in the 100% energy storage status, reduce
the battery discharge times and prolong the working life.

When the mains is normal, the input of UPS (1-10kVA) series converts into the ±360V steady DC
voltage through PFC, which supplies power for DC/AC inverter to output steady 220V AC and

charges battery at the same time. When the mains is abnormal, the battery will boost into the ±360V
DC voltage for DC/AC inverter through DC/DC.

The working principles of UPS (1-10kVA) series is as shown in Figure2-16. The DC/AC inverter
adopts half bridge structure and the DC/DC boost adopts the push-pull circuit or boost circuit. PFC is
the correction circuit for active power factor.

Step 3 Connect the equipped parallel wires with parallel port i n the rear panel of each UPS in the p arallel

system.

1. The wiring method and phase sequence of the input of each UPS in the parallel system should be

the same. Besides, the bypass power of parallel system should be the in-phase.

2. Each UPS in the parallel system is connected to an independent battery pack. It's prohibited that

two UPS use the same battery pack.

3. Connect the equipped parallel wires with parallel port in the rear panel of each UPS in the parallel

system. Two RJ45 parallel ports are the same, that will have redundancy to improve reliability. If
there has a parallel port disconnected, UPS will have an alarm. After connecting the parallel wires,
fasten them in the rear panel holes of each UPS by cable ties.

4.4 Parallel System Operation

4.4.1 Start Parallel System

Don't start loads until parallel system have started completely. Ensure all breakers in the distribution
box are switched off.

Start the parallel system following the procedures as below:

Step 1 After installing parallel system correctly, start each UPS in the parallel system according to 4.2

Startup Operation successively.

Step 2 When each UPS outputs, measure the inverting voltage of each UPS. The voltage difference between

the max. voltage and the min. voltage should be less than 5V. Switch on breakers that connected with
each UPS in th e distribution box in 5min and check the circulation current of each UPS that should
be less than 3A.

If the voltage difference is more than 5V, check if the output of each UPS are all 220V. If the volta ge
difference is more than 10V, please contact your local distributor or service center for help. Besides,
if the circulation current of each UPS is too large, it will damage inverter. If the circulation current of
each UPS is more than 3A, please contact your local distributor or service center for help.

Step 3 Switch on major output breaker and output breakers of each branch in the distribution box. Then start

load successively.

----End

4.4.2 Close Parallel System

Generally, it is not recommended that turn on or turn off the parallel system frequently.

Step 1 Close all loads;
Step 2 Press "OFF" button in the panel of each UPS to shut down UPS successively.

Step 3 Switch off breakers in the rear panel of each UPS.(In the daily operation, it's unnecessary to switch

them off).

4.4.5 Redundancy Funciton of Parallel System

When adopting the N+1 redundancy backup design, the total output load should be less than N times
of rated load of single UPS. If there has a faulty UPS, it will remove form parallel system
automatically, which doesn't influence system running and enhances system reliability. When the
output load is more than N times of rated load of single UPS, the overload unit (more than N/(N+1)
times of rated load of single UPS)will have an alarm. e.g. For the parallel system with two UPS,
when the load of UPS is more than 50%, it will have overload alarm.

4.5 Periodic Preventative Maintenance

To improve the efficiency and reliability of UPS, perform the following maintenance regularly.

4.6 Battery Maintenance

The working life of battery is based on environment temperature and discharge times. Using battery
in the high temperature for a long time or discharging battery deeply will reduce the working life of
battery.

 Charge battery for ten hours before using it. During charging, it can use the battery. If the battery

and charger are powered off at the same time, the discharging time will be less than the standard
value.

 Generally, charge and discharge battery once every four to six months. Discharge battery till the

battery is under-voltage and power it off and then charge it. In the high temperature area, charg
