powered.

8. If optional EBMs are installed, see “Configuring the UPS for
EBMs” to set the number of installed EBMs.

9. To change any other factory-set defaults, see “Operation”
Online series recommends setting the date and time.
At initial startup, the UPS sets system frequency according to

input line frequency (input frequency auto-sensing is enabled by
default). After initial startup, auto-sensing is disabled until
manually re-enabled by output frequency setting.

At initial startup, inut voltage auto-sensing is disbaled by default.
When manually enabled by output voltage setting, at the next AC
startup the UPS sets output voltage according to input line
voltage. After the subsequent startup, auto-sensing is disabled
until manually re-enabled by output voltage setting.

10. If you installed an optional REPO, test the REPO function:
Activate the external REPO switch. Verify that status change on

the UPS display.
Deactivate the external REPO switch and restart the UPS.

4.6 Parallel Installation and Operation

4.6.1 Brief introduction of the redundancy

The parallel structure is 1+1. As long as the UPS is equipped with
parallel function and parallel cables, up to 2 UPSs can be
connected in parallel to configure a sharing and redundant output
power.

4.6.2 Installation and operation

How to install a new parallel UPS system:

1) Before installing a new parallel UPS system, user need to
prepare the input and output wires, the input and output
breakers, and the parallel cable.

26

2) Users need to use a specialty 15-pin communication cable for
this system, which should have 15 cores, corresponding
stitches and shield, as the UPS parallel cable. The length of the
parallel cable is appropriate to be less than 3 m.

3) Strictly follow the chapter of 4, the wiring requirement of single
UPS to perform the wiring of each UPS.

4) Independent battery packs for each UPS.

5) Please connect the input and output wires, fix all the wiring
according to the Figure 4-5 and make sure all these breakers
are open.

29

6) Turn on the input breakers for the two parallel UPS.

7) Pressing button continuously for more than 1 second for
one UPS of the system, then the system will start to turn on and
enter line mode.

8) Regulate the output voltage of the each UPS separately, and
check if the output voltage difference between the two ups is
less than 0.5V. If the difference is more than 0.5V, the UPS
need to be regulated.

9) If the difference output voltage is less than 0.5V, switch on the
output breakers for the two UPS separately and switch on the
main O/P breakers, then the system will work normally in
parallel.

■ The output wiring requirement as follows:

● When the distance between the UPS in parallel and the
breaker panel is less than 10 meters, the length difference
between input and output cable of the UPSs is required to be
less than 20%.

● When the distance between the UPS in parallel and the
breaker panel is more than 20 meters, the length difference
between input and output cable of the UPSs is required to be
less than 5%.

How to join a new UPS to a parallel system:

1) Firstly a main maintenance mechanical switch or static switch
should be installed for the parallel system.

2) Regulate the output voltage of the new UPS: check if the output
voltage difference between the new UPS and the parallel
system is less than 0.5V.

3) Ensure the bypass of the parallel system is normal and the
bypass setting is “enable”, then press the

button to turn off

the UPS, then UPS will work in bypass mode.

30

4) Set the main maintenance switch or static switch from “UPS” to
“BPS”, then switch off the main output breaker and the input
breaker and mains breaker, then the UPS will shut down.

5) Connect the cable and wire of the added UPS according to the
Figure.4-5.a and Figure.4-5.b

6) Switch on the input breakers and mains breaker, and make
sure that every UPS work in bypass mode.

7) Switch on the O/P breakers and main O/P breaker，transfer the
main maintenance switch or static switch from “BPS” to “UPS”.

8) Press the button of one UPS, each UPS would start to turn
on, after that, the two UPS should work parallel in Line mode.

How to remove a single UPS from a parallel system:

1) Firstly a main maintenance mechanical switch or static switch
should be installed for the parallel system.

2) Ensure the bypass is normal and the bypass setting is “enable”,
press the button to turn off the UPS system, and the UPS
system will work in bypass mode.

3) Transfer the main maintenance switch or static switch from
“UPS” to “BPS”, then switch off the output breakers and the
input breakers and mains breaker for the two UPS, and the
UPS would shut down.

4) Switch off the main O/P breaker and O/P breaker for the UPS
system.

5) Remove the wanted UPS and cables and wires.

6) Switch on the mains breaker and input breaker of the reserved
UPS, make sure the UPS work in bypass mode.

7) Switch on the O/P breaker and main O/P breaker.

8) Transfer the main maintenance switch or static switch from

High Efficiency Mode:

After the UPS is turned on, the power

used by the load is supplied from the

utility power via internal filter while the

utility power is in normal range, so the

high efficiency could be gained in the

HE mode. Once the mains is loss or

abnormal, the UPS would transfer to

Line mode or Battery mode and the

load is supplied continuously.

1) The function could be enabled
through the LCD setting or the

This chapter explains how to:

 Care for the UPS and batteries
 Transport the UPS
 Store the UPS and batteries
 Test the batteries
 Recycle the used Battery or UPS

6.1 UPS and Battery Care

For the best preventive maintenance, keep the area around the UPS
clean and dust-free. If the atmosphere is very dusty, clean the outside of
the system with a vacuum cleaner. For full battery life, keep the UPS at
an ambient temperature of 25°C (77°F)

Note: The batteries in the UPS are rated for a 3-5 year service life. The
length of service life depends on the frequency of usage and ambient
temperature. Batteries used beyond expected service life will often have
severely reduced runtimes. Replace batteries at least every 5 years to
keep units running at peak efficiency.

6.2 Transporting the UPS

NOTE: The internal UPS batteries MUST be disconnected before

transport.
CAUTION: The following procedure should be performed or supervised

by personnel knowledgeable about batteries and the required precaution.
Keep unauthorized personnel away from batteries.

If the UPS requires any type of transportation, the batteries must be
disconnected (but not removed) before the unit is transported:

1. Verify that the UPS is off and disconnected from utility power.

2. Place the UPS on a flat, stable surface with the front of the cabinet
facing you.

3. Remove the UPS front cover
