After connecting L1&L2 and N1&N2, it becomes one low-voltage output (104/110/115/120V) at L1-N1 for
100% of UPS rating power. Connect load to L1-N1 or L2-N2.

Option 3:
The output of ISO bank
After connecting N1 and L2, it becomes one high-voltage output (208/220/230/240V) at L1-N2 for 100% of
UPS rating power. Connect load to L1-N2.
★
Option 4:
The output of ISO bank
After connecting N1&L2, it becomes three outputs, one high-voltage output (208/220/230/240V) at L1-N2
and two low-voltage outputs (104/110/115/120V) at L1-N1 & L2-N2. However, there is a limit for current
rating at L1-N1 & L2-N2: 25A for 6K(L) model and 42A at 10K(L) 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 1:
If any load current in L1-N1 or L2-N2 is higher than 25A in 6K(L) model and 42A in 10K(L) 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. Hence, the
installation must be done with technician and make sure that the load current does not exceed this
limitation.
NOTE 2:
When 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 because high-voltage is generated by shorting
N1-L2.
If it’s required to keep connected load in isolated status, we recommend that you may only use two
low-voltages 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.
