● Place the UPS near the mains socket to cut off AC mains without any delay at any emergent case.

Attention:

●Make sure the load behind the UPS is off when users connect the load to UPS, and then turn on the load
one by one later.

●Please connect the UPS with the socket which is over-current protected. Do not connect the UPS with the

socket which rated current is less than the Maximum input current of the UPS.

●All the power socket should be configured with earthling device for safety.

●UPS could be electrified or powered no matter the input power cable is tied or not, even when the UPS is off.

The only way to cut off the output is switching off the UPS and disconnecting the mains power supply.

●For all standard type UPS, it is advised to charge the battery over 8 hours before used. Once the AC mains

power energizes the UPS, it will automatically charge the battery. Without prior charging, UPS output
remains as usual but with shorter back-up time than normal.

●When connected to motor, display equipment, laser printer etc, UPS power selection should be based on
the startup power of the load which is usually twice as rated power.

③Please install the output breaker between the output terminal and the load, and the breaker should

be qualified with leakage current protective function if necessary.
B. Insert the EPO plug into the EPO slot on the real panel.
C. Put the terminal block cover back to the rear panel of the UPS.
Warning: (only for long-run model)
◇Make sure a DC breaker or other protection device between UPS and external battery pack is installed. if

not, Please install it carefully. Switch off the battery breaker before installation.

Note: Set the battery pack breaker in “OFF” position and then install the battery pack.

◇Pay highly attention to the rated battery voltage marked on the rear panel. if you want to change the

numbers of the battery pack, please make sure you modify the setting simultaneously. The connection with
wrong battery voltage may cause permanent damage of the UPS. Make sure the voltage of the battery
pack is correct.

◇Pay highly attention to the polarity marking on external battery terminal block, and make sure the correct

battery polarity connected. Wrong connection may cause permanent damage of the UPS.

◇Make sure the protective earth ground wiring is correct. The wire current spec, color, position, connection

and conductance should be checked carefully.

◇Make sure the utility input＆output wiring is correct. The wire current spec, color, position, connection and

conductance should be checked carefully. Make sure the L/N site is correct, not reverse or short-circuited.

Output Configuration
★Option 1:

There are 2 sets of low-voltage output (100V/110V/115V/120V) with L1-N1 and L2-N2. Each of them is able to

6

provide 50% of UPS rating power. Connect one load to L1-N1 and the other load to L2-N2.

★ Option 2:

After connecting L1&L2 and N1&N2, it becomes one low-voltage output (100V/110V/115V/120V) at L1-N1 for
100% of UPS rating power. Connect load to L1-N1 or L2-N2.

★ Option3:

After connecting N1 and L2, it becomes one low-voltage output (208V/220V/230V/240V) at L1-N2 for 100%
of UPS rating power. Connect load to L2-N1

★ Option4:

After connecting N1＆L2, it becomes three outputs, one high-voltage((208v/220v/230v/240V) at L1-N2 two
low-voltage outputs (100v/110v/115v/120V) at L1-N1 and L2-N2. However, there is a limit for current rating at
L1-N1 and L2-N2: 25A is for 6KVA model and 42A is for 10KVA model. You must connect the load under the
limitation. Please read Note first before installation.
Connect low-voltage load to L1-N1 and L2-N2, and connect high-voltage load to L1-N2.

Note: ①if any load current in L1-N1 or L2-N2 is higher than 25A in 6KVA model and 42A in 10KVA model.

The UPS will still operate normally without overload warning because the total load is under the
specification. However, the isolation transformer will be damaged with overheat due to high current.

exceed this limitation.

②When connecting to low-voltage and high –voltage at the same time like option 4, it will cause the

L1-N1＆L2-N2 with low-voltage loads in Non-Isolated status, we recommend that you may only use
two low-voltage at L1-N1 or L2-N2 like option 1, and also make sure that the total current in L1-N1 or

L2-N2 does not exceed the value on Note 1.

2.5 External battery connection procedure for long back up type

●For different UPS type, users are instructed to configure different battery voltage as below sheet. More or

less units are forbidden, or else something abnormal or faulty will appear.

●One end of battery cable is for UPS terminals while the other end with triple cables is for battery terminals.

Correct installation procedure is highly vital or else probable electric shock will arise. Users are strictly
required to follow the below procedure.

●Connect battery in correct way and make sure the total battery voltage is available for UPS.

●Correctly connect the long battery cable to battery terminals first, red wire is to positive plate while black is to

negative. If users connect the UPS first, electric shock or other danger could not be avoided.

●Before connecting load after UPS, users should supply main power to UPS and energize it.

●Connect long battery cable to UPS terminals with correct poles link (red is for “+”, black is for“-”), UPS will

start the charging work automatically.

2.6 Installation

●UPS installation work should comply with local electrical standard and only can be done by professional

technician. 1KVA~3KVA units could use wall socket as input power connection.

●For all type UPS, it is advised to charge the battery over 8 hours before the first use. Once the AC mains

power energizes the UPS, it will charge the battery automatically. Without prior charging, UPS output
remains as usual but with shorter back up time than normal.
