4．Operation
4.1 Operation Modes
The UPS is a double-conversion on-line UPS that may operate in the following 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. The inverter converts the DC
power to AC and supplies to the load.
Battery mode (Stored Energy Mode)
KE 4256-3230 Keatec T Series UPS 10-40K 380Vac Users Guide English 20170126 This manual is for qualified personnel only.
Page 16
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).
ECO Mode
When the UPS is at AC Mode and the requirement to the load is not critical, the UPS can be set
at ECO mode in order to increase the efficiency of the power supplied. In ECO mode, the UPS
works in Line-interactive mode, so the UPS will transfer to bypass supply. When the AC is out of
the set window, the UPS will transfer from bypass to Inverter and supplies power from the battery.
The LCD shows all related information on the screen.
Parallel redundancy mode (system expansion)
To achieve a higher capacity and / or increase reliability, the outputs of up to four UPS can be
programmed to operate in parallel. Each UPS has a built-in parallel controller and coordinates
with the other UPS using a control cable to manage load sharing automatically.
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 and this manual bypass switch bears for equivalent rated load.
4.2 Turn On / Off UPS
4.2.1 Restart procedure
CAUTION!
Make certain grounding is correct and secure.
◆ Set the Battery Breaker to the “ON” for long run UPS.
◆ Switch ON the power switch for standard UPS.
