4. Operation

4.1 Over-Temperature Protection

4.1.1 Over-Temperature Red Warning LED Light

The transformer includes a warning LED light on the top portion of the front panel. The light turns ON when the 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 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 an over-temperature protection relay and thermal switch to protect the transformer from overheating.

At 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 output breaker of the transformer. Once the transformer temperature has cooled

down and the warning LED light has turned OFF, you may manually re-activate (close) the output breaker to restart normal

operation.

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

each UPS.
