low-voltage
Circuit breaker turns off the
power of the control box.
▶
Input Voltage: this indicates the secondary voltage of
the transformer in the AMP box and output voltage
through the transformer when the user inputs the AC
200 ~ 240V.
Do not use under the different voltage conditions. This causes the equipment damage.
Caution
When the AMP box powers on, the voltage display LED color should be green.
If the LED color is red or yellow, the input power is not consistent with the specifications. Please
contact our repair center engineer.
