3.5.3 Connect devices to UPS

After the UPS is turned on, you can connect devices (load) to the UPS.

1. Turn on the UPS first and then switch on the devices one by one; the LCD panel will display total
load level.

2. If inductive loads needed to be connected, such as a printer, the in-rush current should be
calculated carefully to see if capacity of the UPS can handle the in-rush.

3. If the UPS is overloaded, the buzzer will beep twice every second.

4. When the UPS is overloaded, remove some loads immediately.

i. If the overload timer expires while in Line Mode, the UPS will automatically transfer to Bypass

mode. After the overload is removed, it will return to Line mode.

ii. If the overload timer expires while in Battery Mode, the UPS will enter fault status.

1. At this time, if bypass is enabled, the UPS will power the load via bypass.

2. If bypass function is disabled or the input power is not within bypass acceptable range, it
will cut off output immediately.

3.5.4 Charge the batteries

1. After the UPS is connected to the utility power, the charger will charge the batteries
automatically except in Battery mode or during battery test.

2. It is suggested to charge batteries at least 10 hours before use. Otherwise, the backup time may
be shorter than expected.

3. Make sure the battery numbers setting on the control board (refer to the section of changing
battery quantity) is consistent with actual connection.

3.5.5 Battery Mode operation

1. When the UPS is in Battery mode, the buzzer will beep according to different battery capacity.

i. Buzzer will beep once every 4 seconds in battery mode,

ii. When the battery voltage drops to the alarm level, the buzzer will beep once per second and

the UPS will shut down automatically soon.

1. Users could switch off some non-critical loads to disable the shutdown alarm and prolong
the backup time.

2. If there is no more load to be taken off at that time, shut down all loads as soon as
possible to protect the devices or save data. Otherwise, there is a risk of data loss or
load failure.

2. In Battery mode, you could enter “Control->Mute” on LCD to silence the buzzer. See 3.6.2.2
Control items.

3. The backup time depends on the external battery capacity.

4. The backup time may change under different environment temperature and load type.

5. The maximum backup time is limited by default 16.5 hours (After discharging 16.5 hours, UPS
will shut down automatically to protect the battery). The time could be modified through LCD
panel or communication port.

3.5.6 Test the batteries

1. If you need to check the battery status or performance when the UPS is running in Line /
Converter / ECO mode, you could enter “Control->Batt Test” to instruct the UPS to do battery
test. See 3.6.2.2 Control items.

2. Battery test can be set through monitoring software.

3. If the UPS is in battery testing, “Battery test mode” will be displayed on LCD, the buzzer indication
will be the same as Battery mode, but both line LED and battery LED will be lit.

UPS will be turning off to bypass mode while beeping once. You could also enter the “control
menu” to select the instruction “Turn Off” to turn off the UPS. See 3.6.2.2 Control items.

NOTE: “Turn Off” means that UPS is not working on line / converter / ECO / battery / battery test

mode. So even though the UPS is turned off, if input or bypass voltage is normal, the internal
power supply will still be working; if bypass status has been set to “enable”, the output voltage
of the UPS will still exist.

3. To fully cut off the output, please switch off the external input breaker. A few seconds later, there
is no display shown on the panel and UPS is completely off.

The Staco UPS has a long design life. Due to the characteristics of the part, not the design of the UPS,
certain components used in the design have a limited life, even with proper maintenance.

Service and maintenance work must be performed only by factory authorized personnel.

Staco recommends these limited-life components be periodically inspected and replaced before the
expected expiration of their life cycle. The recommended replacement schedule is an estimate only. The
life of these parts depends on site conditions such as ambient temperature, load profile, cleanliness of
environment and other factors.

Staco Recommends a Factory Authorized Preventative Maintenance review is schedule at least once a
year.

The functional lifetime of VRLA batteries is significantly affected by the temperature at which they are
stored and operated. Ideally, VRLA batteries should be used in a 25º C (77º F) environment. For every

8.3º C (15º F) increase in temperature, the life expectancy of a battery will be halved.

Exposure to temperatures in excess of 32º C (90º F) should be limited to no more than 30 days per year.
Under no circumstances should the VRLA battery be exposed to temperatures over 40º C (104º F) which
can lead to thermal runaway, a condition that damages the battery. Thermal runaway can cause
batteries to swell. If the battery cases burst, the hazardous contents may be exposed.

Maintaining proper ambient temperature usually requires installing the product in a temperature
controlled space. Equipment rooms without cooling systems do not generally maintain the proper
conditions for good battery life.

Appendix – Optional Parallel UPS Systems

Requirements: Two parallel cables and two share current cables.

Parallel Operation requires a factory installed Paralleling Kit. (SCV-PAR-10)

At the rear of the unit; if plastic covers over (2) DB9 holes then the kit is NOT installed.

Figure 22: UPS Parallel Communication ports

A.1 Wiring Connection for Parallel Operation

Please follow below steps to connect cables for parallel models.

1. Please follow below figure to connect parallel cable and share current cable.

See Figure 21.

Page | 38

2. Input and output grounding wires are directly connected to the case. Refer to below chart for the

Interface

Setting

-> - >

You c an c hoose Add or Sub to
adjust i nverter v oltage. A nd the

input/output terminal wire connection.

3. If the UPS is connected to external battery pack, it’s required to install battery breaker (DC type)
in each UPS.

A.2 Calibration

Verify items below before powering up the parallel system, in order to make sure UPS module parallel
properly.

1. Make sure that the parallel board and OP relay board have been installed.

2. Make sure that each UPS has the same configuration (See 3.6.2.5 Setting Menu):

a) output voltage,
b) output frequency,
c) bypass voltage range,
d) bypass frequency range,
e) converter enable or disable,
f) bypass enable or disable,
g) bypass open or forbidden,
h) frequency auto detect enable or disable,
i) inverter short clear enable or disable

3. Turn on each UPS into the line mode or battery mode respectively (see 3.5.1 Turn on the UPS with
utility power supply (to Line mode)). Measure and calibrate the output voltage with a multimeter.

Make sure the difference of the output voltage among the UPSs is less than 2.0V (typical 1V). If not,
you can adjust the voltage via LCD as below (See 3.6.2.5 Setting Menu).

voltage range i s from 0V t o 9. 9V,
the default value is 0V.

4. After ad justing the i nverter v oltage, c heck if the output v oltage de tection i s o k. If the di fference
between the displayed value and t he voltage measured by a multimeter is more than 1V, please
adjust it to make sure the difference is less than 1V. Then, shut down the UPS to save this setting
into EEPROM.

2. Turn on the parallel system

Master

Slave1

Slave2

With utility power supply (in AC mode)

a) Turn the breakers on for each battery pack and then turn on the input breaker and power on UPS

one by one.

NOTE: The parallel UPSs cannot use the same battery pack. Each UPS should be connected
to its own battery pack.

• At this moment, the fan is running and the UPS starts to initialize.

• Several seconds later, UPSs operate in Bypass mode.

• After a delay, UPS output relays close.

• Then, parallel system supplies power to the loads via the bypass.

b) Check i f the pa rallel i nformation in LCD d isplay is s hown as in below p ictures. If p arallel UP S

systems are successfully set up, it will show “Parallel: Master”, “Parallel: Slave1” or “Parallel:
Slave2”.

Note: If not , please do not go to nex t s tep and c heck i f t he par allel c ables hav e been c onnected
properly.

c) Press and hold the “ON” button for 0.5s and turn on the UPSs one by one.

Without utility power supply (in Battery mode)

a) Turn on the battery breaker.
b) Press the “ON” button of one UPS to turn on the power supply.

• UPS will enter power on mode.

• After initialization, UPS will enter No Output mode.

c) Within 15 seconds, press “ON” button again to turn on UPS
d) A few seconds later, after UPS is on, the UPS will enter Battery mode.
e) Then, repeat step b) and c) for remaining UPSs.
f) The parallel system has been installed and starts to supply power to the load.

3. Turn off the parallel system

Press and hold the “OFF” button to turn off the UPS one by one. The buzzer will beep once. After a
delay, the UPS will enter bypass mode or no output mode synchronously.

4. Add one new unit into the parallel system

a) You cannot add one new unit into the parallel system when whole system is running. You must

remove the load and shut down the system first.
b) Make sure all of the UPSs are the parallel models and follow the connection diagram in step 1
c) Install the new parallel system.

5. Remove one unit from the parallel system

a) Press the “OFF” button twice. The U PS will enter into bypass mode or no output mode without

output.
b) Turn off the output breaker of this unit.
c) Turn off the input breaker of this unit.
d) After it shuts down, move the parallel cable and share current cable.
e) Remove the unit from the parallel system.
