disconnect the power plug before you open the door to the electrical box.

CAUTION: The power supply from the product or generator must be sufficient and
constant to make sure that the motor operates without problems. Incorrect voltage
causes the power consumption and the temperature of the motor to increase until
the safety circuit releases. The dimension of the power cord must agree with national and local regulations.
