Uninterruptible Power Supply
Confirm the UPS output voltage through the front panel and verify that it matches the transformer box
output voltage.
For example, if the input to UPS is 208V, then voltage selection should be 208V.
There are 3 different output configurations on transformer box
The follow figure shows the transformer box block diagram. The I/O terminal block is hardwired. Before
making hardwire, please be sure the power is completely off.
Switch off utility power at the distribution point where the transformer box will be connected.
Be absolutely sure there is no power.
Verify that the output circuit breaker is in the OFF position.
Three output configurations and the wiring is listed as below:
Option 1: Connect L1 and N to get 120V output
Option 2: Connect L2 and N to get 120V output
Option 3: Connect L1 and L2 to get 240V output
● Do not overload the transformer box. For 120V output voltage, the output of L1 or L2 can only be
half-loaded.
