2. Power Cable
Cut off the power before installing or removing the power cable.
Before connecting the power cable, make sure the cable connection and labels
on the cable comply with the actual installation situation.
Do not install or remove the power cable when the power is ON.
Sparks or electric arc may happen when the power cable touches the conductor,
which may cause fire or eye injury.

splashes may enter the cabinet and cause the short circuit on the circuit board.
When drilling on the cabinets is needed, wear insulating gloves and remove the
cables inside the cabinet before the operation. Take care of your eyes when
drilling, because metal splashes may hurt your eyes. Clean up the metal filings
once the drilling is done.
Do not drill on the cabinet at will.
