4. Operation

WARNING:
It is not advised to connect two UPS in parallel when using individual transformers for each UPS.

4.1 Over-Temperature Protection

4.1.1 Over-Temperature Warning LED Light (Red)
The transformer includes two warning LED lights on the top portion of the front panel: one light for the input transformer and
one light for the output transformer. The corresponding warning light may turn ON when the secondary side of the input (T-in)
or when primary side of the output (T-out) transformer reaches a temperature of 160°C ± 5°C, i.e. a range of 155°C to 165°C
(311°F to 329°F). The warning light turns OFF when the transformer cools to a temperature of 125°C ± 5°C, i.e. a range of
120°C to 130°C (248°F to 266°F).

4.1.2 Over-Temperature Protection Relay and Thermal Switch

The transformer includes two warning LED lights on the top portion of the front panel. One light for the input transformer and
one light for the output transformer. The corresponding warning light will turns ON when the secondary side of the input (T-in)
or when primary side of the output (T-out) transformer reaches a temperature of 160°C ± 5°C, i.e. a range of 155°C to 165°C
(311°F to 329°F). The warning light turns OFF when the transformer cools to a temperature of 125°C ± 5°C, i.e. a range of
120°C to 130°C (248°F to 266°F).
·
Input Transformer (T-in): If the secondary side of the (T-in) input transformer reaches temperatures of 160°C ± 5°C, i.e.
a range of 155°C to 165°C (311°F to 329°F), an over-temperature protection relay and thermal switch will activate and will
open the breaker on the secondary side of the transformer. Once the transformer temperature has cooled down to 125°C ±
5°C, i.e. a range of 120°C to 130°C (248°F to 266°F) the warning LED light will turn OFF, and you may manually re-activate
(close) the output breaker on the transformer to restart normal operation.
·
Output Transformer (T-out): If the primary side of the (T-out) output transformer reaches temperatures of 160°C ± 5°C, i.e.
a range of 155°C to 165°C (311°F to 329°F), an over-temperature protection relay and thermal switch will activate and will
open the breaker on the primary side of the transformer. Once the transformer temperature has cooled down to 125°C ±
5°C, i.e. a range of 120°C to 130°C (248°F to 266°F), the warning LED light will turn OFF, and you may manually re-activate
(close) the input breaker on the transformer to restart normal operation.
