2) Bypass input and AC input of main road must be connected to the same Neutral
3) The outputs of all the single UPS must be connected to a common output bus.
4) The length and specification of power cables including the bypass input cables and the
UPS output cables should be the same. This facilitates load sharing when operating in
bypass mode.
19
4.Operation
4.1 Operation Modes
The UPS is a double-conversion on-line UPS that may operate in the following alternative
modes:
◆Normal mode
The rectifier/charger derives power from the AC Mains and supplies DC power to the
inverter while floating and boosting charge the battery simultaneously.
Then, the inverter
converts the DC power to AC and supplies to the load.
◆Battery mode (Stored Energy Mode)
If the AC mains input power fails, the inverter, which obtains power from the battery,
supplies the critical AC load. There is no power interruption to the critical load. The UPS will
automatically return to Normal Mode when AC recovers.
◆Bypass mode
If the inverter is out of order, or if overload occurs, the static transfer switch will be activated
to transfer the load from the inverter supply to bypass supply without interruption to the critical
load.
In the event that the inverter output is not synchronized with the bypass AC source, the
static switch will perform a transfer of the load from the inverter to the bypass with power
interruption to the critical AC load. This is to avoid paralleling of unsynchronized AC sources.
This interruption is programmable but typically set to be less than an electrical cycle e.g. less
than 15ms (50Hz) or less than 13.33ms (60Hz).
◆Maintenance mode (Manual Bypass)
A manual bypass switch is available to ensure continuity of supply to the critical load when
the UPS is out of order or in repair. This manual bypass switch is fitted for all UPS modules and
bears for equivalent rated load.
◆Redundancy mode
Based on different demands, The UPS can be set as N+X redundancy mode to increase the
reliability to the load connected.
4.2 Turn on/off UPS

CAUTION!
MAKE SURE GROUNDING IS PROPERLY DONE!
◆ Set the Battery Breaker to the “ON” position according to the user’s manual.
◆ Open the front and rear doors of the UPS to access to the main power switches.
During this procedure the output terminals will become alive.
CAUTION!
Check to see if the load is safely connected with the output of the UPS. If the
20
load is not ready to receive power from the UPS, make sure that it is safely
isolated from the UPS output terminals
◆ Check the status of the power switch of the monitoring module. Defualt is set at “ON”.
Turn ON the power switch of the monitoring module, so that the UPS system can communicate

When AC MAINS input voltage within the range, And the rectifiers of the UPS will be started
up in 30 seconds, then the inverter is started completely. When the output breaker is “ON”, the
inverter LED lights up.
◆ Switch ON all output breakers, which locate at module’s front panel.
If the rectifier of the module does not start-up, the bypass LED will light up.
When the inverter is on, the UPS will transfer from bypass mode to inverter mode,
then the bypass LED is off and the inveter LED is on.
No matter the UPS is operated normally or not, the LCD display will indicate
current status.
4.2.2 Test procedure
CAUTION!

◆ Turn on MAINTANCE breaker;
◆ Open BATTERY breaker;
◆ Switch OFF the MAINS breakers of all modules
◆ Open all OUTPUT breakers;
At this time the bypass source will supply to the load through the MAINTENANCE
breaker.
Switch to normal operation (from mechanical bypass)
CAUTION!
Never attempt to switch the UPS back to normal operation until you have verified
that there are no internal UPS faults
◆ Open the front and rear doors of the UPS to be easily access to the main power
switches
◆ Switch ON the output breakers of the modules.
◆ Switch ON the input breakers of the modules.
The UPS powers from the static bypass instead of the maintenance bypass, then
the bypass LED will light up.
◆ Switch OFF the maintenance bypass breaker, then the output is supplied by the
bypass of the modules.
◆ Put on the maintenance switch cover.
The rectifier will operate normally after 30 seconds. If the inverter works normally, the
system will be transferred from bypass mode to normal mode.
4.2.5 Shut down procedure
CAUTION!
This procedure should be followed to completely shut down the UPS and the
LOAD. After all power switches, isolators and circuit breakers are opened,
there will be no output.
◆ Press the INVERTER OFF button on the right side of the operator control
panel for about two seconds;
◆ The Inverter LED will be extinguished and audible alarm comes
simultaneously.
◆ Open the BATTERY breaker;
◆ Open the UPS door to easily access to the main power switch;
◆ Switch OFF the input breakers of all modules.
◆ Open the OUTPUT power switch. The UPS shuts down;
◆ To completely isolate the UPS from AC Mains, all input switches of Utility
shall be completely off, which includes the ones for rectifier and bypass.
◆ The primary input distribution panel, which is often located far away from the
UPS area, so a label should be posted to advise service personnel that the
UPS circuit is under maintenance。

WARNING!
Wait for about 5 minutes for the internal D.C. bus bar capacitors to be
completely discharged.
4.2.6
Startup procedure for parallel system
 Connect parallel cable, input/output cable, battery cable well; modify the parallel
board jumpers correctly.
 Measure the positive and negative battery pack voltage. Battery breaker is opened
temporarily.
 Check if the power switch of monitoring module is closed. The default is closed.
 Close the output switch of power distribution unit at the front door.
 According to the startup procedure for single unit, set the operation mode of each
UPS: single mode is changed to parallel mode; set the parallel number for each
UPS; up to 4 units can be parallel; set the ID of each cabinet, the ID of each unit
must be different.
 Close the breakers of all the power module. Close the external input switch and
start from mains.
 After start from mains, check the LCD interface of each UPS to see if the ID, VA is
the same with the actual values.
 Close the external battery breaker of each UPS. Check if the charging current
displayed in LCD is normal.
Note!
The UPS cannot be parallel until each single unit is normal.
