9.- OPERATION: SINGLE UPS

This is a True On Line Double Conversion UPS and it is designed to offer clean, bump-less and highest quality power to your computer related

equipments protecting also your valuable data. Power delivered by UPS is 100% sine wave as main line.

According to AC Line status the UPS may operate in following modes:

ONLINE NORMAL Mode

When UPS is turned off by selecting ON push button in front panel and AC Line is normal it enters into ONLINE NORMAL mode. Under this mode

UPS Inverter powers outputs and the energy is taken from DC voltage coming from AC/DC converter. Batteries are charged by AC Line if

required.

BATTERY Mode (Also known Inverter Mode)

Under ONLINE NORMAL mode when UPS detects a problem in AC input Line or black out it enters in battery mode. Under this mode UPS takes

energy from its batteries to power outputs. There are no transfers neither micro-cuts on UPS outputs as inverter was already working, the only

difference is that energy for outputs is now coming from batteries. Transfer time is actually Zero (0 ms).

UPS also can enter in battery mode when it is turned on without an acceptable AC input.

ECO Mode

There is an energy saving function that makes UPS to power its outputs with AC Line directly. If under this mode, UPS detects AC input is out of

acceptable range it enters into Normal Online mode.

If an AC failure occurs under ECO mode the UPS’s inver ter starts working draining energy from batteries. There is a transfer time of 4 ms typical.

This mode is configured and activated from LCD panel. There is specific input voltage range and input frequency range to configure for ECO

mode.

BY PASS Mode UPS 3/1

Under BYPASS mode, UPS outputs are powered by AC Line.

Since this is a 3 phases input / 1phase output UPS, in BYPASS model all required input current is conducted through Line 1 (L1 or "R").

This mode can be caused by operator by means of the maintenance switch (on the rear panel) or from LCD panel when OFF button is activated,

but it may also happen automatically by UPS malfunction or overload detected at UPS outputs.

FREQUENCY CONVERSION Function

This UPS offers a very sophisticated function named frequency conversion (CF) that allows UPS to generate power output at determined

frequency value (50Hz or 60Hz) no matter input frequency value. UPs will be able to generate output at 50Hz even input source is at 60Hz or

generate 60Hz even if connected to 50Hz source.

This function can be configured and activated by LCD. Revise configuration section of this manual.

IMPORTANT NOTES:

1.- Under CF mode, UPS will disable BYPASS mode. Since UPS has been configured to generate output with frequency value different to input

frequency, BYPASS mode is disable to avoid a not acceptable frequency value at output.

2.- When CF function is activated, maximum power output is de-rated to 60% of maximum nominal capacity. For example, for a 10KVA (8KW)

model, when CF is activated maximum output is decreased to 6KVA (4.8KW).

10.- OPERATION: PARALLEL UPS

UPS operation modes for UPS in parallel are basically same than described for single UPS. However it is important to remark all UPS in parallel system must work under same mode at same time. Parallel function does not allow different operation modes between UPS of the system.

Removing an UPS from a Parallel System

There are 2 procedures to isolate and remove one UPs from operative parallel system:

A) Total Power-Off:

Powering off all UPS of the system. This is the less risky procedure.

B) Keeping Parallel system in ONLINE mode:

First check all below requirements are complied before trying to follow this procedure.

Requirements for removing one UPS in operative UPS:

1.- This operation must be performed only by qualified and trained personnel.

2.- This operation must be coordinated with the system administrator. System administrator must know about the related risks of this procedure since the system could be shut down during operation because external reasons like:

- If during this operation occurs a failure in main AC line, battery backup of remaining UPS could not be enough to keep system running before reconnecting removed unit.

- External breakers could be activated randomly during operation so system could be tripped.

3.- There must be a detailed plan to perform this procedure identifying all maintenance activities to be performed on removed unit before reconnecting it.

4.- Remaining UPS must be able to support the power system after selected unit is removed.

5.- Each UPS must have their own external protections to allow total electrical isolation

6.- There must be enough physical room to allow comfortable access to all UPS of the system.

Note: if any of the above requirements cannot be complied, below procedure must not be performed.

In case all requirements can be complied proceed as follow:

1.- Power off selected UPS by OFF button in front panel. Note: OFF button must be selected twice. If OFF is selected only one time, UPS will not respond. Once UPS is turned off it will shut down its outputs but remaining LCD on. This UPS will not go to bypass mode since it is working in UPS system with other UPS generating their output from their inverters. At this moment any failure in AC main line must be supported by operative UPS.

2.- Set AC input breaker located in rear panel of the selected UPS to OFF position.

3.- Set external output breakers of selected UPS to OFF position.

4.- Set external input breakers of selected UPS to OFF position.

5.- Once LCD is turned Off, in selected UPS to be isolated, disconnect control parallel cables (parallel cables and current share cables) from its rear panel. Other operative UPS must keep their control parallel cables connected. NOTE: If you disconnect parallel control cables in any of the operative UPS of the system, a communication problem will occur and the parallel system will be shut down.

At this moment selected UPS is currently powered off and isolated so that it can be serviced or simply removed.

Adding an UPS to a Parallel System

• For adding a new UPS to an operating system, all UPS must be turned off and all equipments must be disconnected from UPS outputs.

• Total UPS quantity must be 3 or lower.

• Firmware of all UPS must be compatible for allowing parallel functionality.

• New UPs must be configured with similar LCD configuration menu than current UPS of the system.

• Follow the procedure explained in Installation Section of this manual.
