5. Operation Principles

5-1. Block diagram of UPS

Figure 5-1 Wiring diagram for dual inputs

Figure 5-2 Wiring diagram for single input

Page 45

5-2. Operation Mode

This UPS is a three-phase, four-wir e on-line, double-conversion and reverse-transfer UPS that permits operation in the following modes:

 Standby Mode  Line Mode  Battery Mode  Bypass Mode  ECO Mode  Shutdown Mode  Maintenance Bypass Mode (manual bypass)

5-2-1. Standby Mode

Upon connecting to utility input power, the UPS is in St andby mode unless UPS is turned on (if BYPASS enable setting is Di sabled), and charger fun ction will be active when the batt ery is connected. The load is not powered under this mode.

Standby Mode Diagr am

5-2-2. Line Mode

In Line Mode, the recti fier delivers power from the mains and supplies DC power to the inverter and the charger charge s the bat tery. The inve rter fil ters t he DC p ower and convert s it int o pure and stabl e AC p ower

Page 46

to the load.

Line Mode Diagram

5-2-3. Battery Mode

The UPS a u tomatically tr an sfe r s t o Battery m od e if the Utility f ail s. There is no inte rr uptio n to the load up o n failure. In battery mode, the rectifier delivers power from the battery and supplies DC power to the inverter. The inverter filters the DC power and converts it into pure and stable AC power to the load.

Page 47

Battery Mode Diagram

5-2-4. Bypass Mode

Upon co nnecti ng to utili ty inp ut po wer, the UP S is i n Byp ass mo de be fore UP S is t urned o n (if BYPA SS ena ble setting is Enabled), and charger function wil l be a ctive when bat tery is connected.

After UPS has been turned on, if the UPS encounters abnormal situations (over-temperature, overload …, etc.), the static transfer switch will perform as a transference of the load from the inverter to the bypass source with no interr up tion. If the transference i s caused b y a reco v e r a b l e re ason, the U P S wi l l t urn back t o line mode when abnormal situation has been solved.

Bypass Mode Diagram

Page 48

5-2-5. ECO Mode

The ECO Mode can be enabled through the LCD control panel. In ECO mode, the load is diverted to bypass when the bypass voltage and frequency are within the acceptable ranges. If the bypass is out of range, the UPS will tr an sfer the power source o f l oad from b yp ass to inverter. In order to shorten the transfer time , t he rectifier and inverter are working when the UPS is in ECO mode.

ECO Mode Diagram

5-2-6. Shutdown Mode

When the UPS is in the off state and the utility power source is absent, the UPS will enter into shutdown mode. Or when the UPS has discharged the battery to the cut-off level, the UPS will also enter into shutdown model. When the UPS enters this mode, it is going to shut off the control power of UPS. The rectifier, charger and inverter will be all shutdown.

Page 49

Shutdown Mode Diagram

5-2-7. Maintenance bypass Mode

A manual bypass switch is available to ensure continuity of supply to the critical load when the UPS becomes unavailable e.g. du ring a maintenance procedure. Before entering the maintenance bypass mode, make sure the bypass power source is normal.
