PowerWalker VFI RT HID Series

I. Assembly

The UPS can be assembled in a rack form using rack ears (Rack Mount Kit is not included) or in

tower form using tower holder. The LCD part can be taken out and turned 90 degrees to align

with orientation of the UPS.

Internal batteries are disconnected for transportation. It is necessary to open front panel (2

screws on the side, 1 screw behind the LCD) and connect the two available connectors before

first usage. External batteries are connected in front using third connector.

V. Connection of the UPS

The UPS should be protected with circuit breaker on the

input. Minimum rating should 10A for 1000VA, 12A for

1500VA, 16A for 2000VA and 20A for 3000VA. For output

connection please use original cables and share the load

equally among outlets.

VI. Connecting Battery Packs

Remove front panel, connect the battery via Anderson PP45 connectors. Make sure you

are connecting with correct polarity (red to red, black to black). Make sure the wires are

connected tight. Close front panel. Setup the amount of battery packs in the settings.

VII. Communication Ports

A Local communication with the software can be

established via USB or RS232 connector. Alternatively UPS

can be controlled using dry contacts.

IX. Dry contact port and EPO

The relay output contact must not be connected to any utility connected circuits.

Reinforced insulation to the utility is required. The relay output contact has a maximum

rating of 30Vac/1A.

The signal input to control UPS On/Off status is the same as one button to control UPS

On/Off status. The relay output can be configured by protocol command:

Description

UPS On/Off

One second pulse activate, if active, the UPS turns off when UPS is

on inverter; the UPS turns on when UPS is not on inverter. It is the

same as a remote button to control UPS On/Off status.

For more information visit our website.

X. Extension Slot

UPS allows extending communication means by extension cards. Please check product

website for list of accessories.

XI. UPS Initial Startup

1. Verify that the internal batteries (behind front panel) and optional battery packs are

connected.

2. Plug the equipment (load), but do not turn it on

3. Plug in the UPS input power cord. The UPS front panel display illuminates and UPS

status display shows “INIT” for initialization and then settles on “STbY”

4. Press and hold the ON/OFF button more than 3 seconds. The UPS status display

changes to “LINE”

5. Configure the UPS (i.e. EBM battery settings)

At initial startup, the UPS sets system frequency according to input line frequency.

XII. User Setting String

Settings should be done in standby (no output) or bypass mode. Load Segments can be

also changed in Line Mode

XIII. [UPS] Normal Operating Mode

UPS works in normal double conversion mode, providing clean and filtered power.

XIV. [CVF] Frequency Converter Mode

When input frequency is within 40 Hz to 70 Hz, the UPS can be set at a constant output

frequency, 50 Hz or 60 Hz. The UPS will still charge battery under this mode. Frequency

Converter requires de-rating of the UPS Power to 70%.

XV. [ECO] Economy Mode

It is also referred to as high efficiency mode. The load is supplied directly from mains via

internal filter when input voltage is within the allowed range. If the input is abnormal,

UPS would switch to battery mode. A transfer time up to 10ms is present during switching

to battery mode.

XVI. Configuring EBM quantity

ENGLISH

Setting correct EBM (External Battery Module) quantity is critical for reaching the desired

backup time. Only if this value is set correctly, UPS will be able to maximize the battery

usage. The value represents amount of original battery packs fitted with 2 strings of 9Ah

batteries.

XVII. Configuring Load Segment

Load segments are groups of outlets that can be configured through the display. VFI RT

HID models have two configurable load segments. When UPS is turned on (it has

activated output), you can turn off a load segment. If the UPS is turned off (no output),

then a load segment cannot be turned on.

XVIII. Bypass Mode

If the bypass is set to enabled (value = 001), then the UPS would provide output to the

load as long as there is input. Turning off the UPS would essentially switch off the inverter

and supply unfiltered power to the load.
