When the power is turned on, check that the display unit will change. (See a figure below)

control power is turned on, correct the cause of the abnormal and reboot the control power with care.

Caution concerning Power ON/OFF
】 】 】 】
・
・ ・
・
After turning OFF the power, do not turn power back ON without a brief wait.
(recommended 20 seconds before turning power back on) Single or random
incidents of powering up with less waiting time is acceptable. However, multiple
power ON/OFF in succession may cause the following;
・
・ ・
・
The inrush current protection circuit would shut down the power supply circuit.
・ ・ ・ ・
The power supply circuit would then automatically shutdown. As a result, the
power supply circuit will not work even if the control power is turned back on.
(Auto Protection Circuit keeps OFF condition.)
・ ・ ・ ・
If the control power will not turn back on, wait for at least 5 minutes to reset the
protection circuit and try again.
