2-3. Single UPS installation
Installation and wiring must be performed by qualified personnel, and in accordance with the local electrical regulations and codes.
Also, you must observe the following instructions:
1) Make sure the mains wire and breakers in the building are enough for the rated capacity of the UPS to avoid the hazards
of electric shock or fire.
Note: Do not use a wall receptacle as the input power source for the UPS, as its rated current is less than the UPS maximum
input current. Failure to do so may result in a broken or burned out receptacle.
2) For safety considerations, turn off the mains switch in the building before installation.
3) Turn off all the devices before connecting them to the UPS.
4) Wiring sizes should be installed in accordance with the following table:
Note 1: The cable for 6K should be able to withstand currents of over 40A. It is recommended to use a 10AWG or thicker wire
for safety and efficiency.
Note 2: The cable for 10K should be able to withstand currents of over 63A. It is recommended to use an 8AWG or thicker wire
for safety and efficiency.
Note 3: For single model, it is not necessary to connect the non-isolated neutral terminal.
Note 4: The color selection of wires should be made according to the local electrical codes and regulations.
5) Remove the terminal block cover on the rear panel of UPS. Proceed to connect the wires according to the following terminal
block diagrams: (Make sure to attach the earth wire first when connecting the wires. When removing the wiring, make sure to
remove the earth wire last).
Note 1: Make sure that the input and output wires and the input and output terminals are connected tightly.
Note 2: There are two output terminal configurations to meet customers’ diverse requirements for serial or parallel connection.
Please refer to section 2.4.
Note 3: Install the leak current protective breaker at the output power distribution panel of the UPS, if necessary.
6) Put the terminal block cover back in the rear panel of the UPS.
Warning:
• For safety considerations, switch all power off using the main switch before installation.
Note: The battery breaker must also be set to OFF before installing the battery pack.
• Pay close attention to the rated battery voltage marked on the rear panel. If you want to change the number of batteries, please
make sure you modify the settings accordingly. A connection with the wrong battery voltage may cause permanent damage to the
UPS. Make sure the voltage of the battery pack is correct.
• Pay close attention to the polarity markings on the external battery terminal block, and make sure to match the correct battery
polarity of the cells. Wrong connection may cause permanent damage to the UPS.
• Make sure the protective earth ground wiring is correctly installed. The wire current specification, color, position, connection and
conductance reliability should be checked carefully.
• Make sure the utility input and output wiring is correct. The wire current specification, color, position, connection and conductance
reliability should be checked carefully. Make sure the L/N wiring is correct, not reverse and short-circuited.
2-4. Output configuration
Option 1:
There are 2 sets of low-voltage outputs (104/110/115/120V) on L1-N1 and L2-N2. Each set is able to provide 50% of the UPS rated
current. 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 (104/110/115/120V) at L1-N1 for 100% of the UPS rated
current. Connect load to L1-N1 or L2-N2.
