Safety instructions

Open maintenance requires cutting off the 12-24V DC power supply, restoring all chassis covers after repair, and then powering them back on.

The shell is running at high temperature, and it should be touched after cooling down to prevent burns.

RTC button lithium battery: There is a risk of explosion if the wrong model is replaced, and the waste battery is recycled in compliance.

Keep away from liquids and dust, and do not cover the heat dissipation fins; Only use UL/IEC certified 12-24V power supply.

Only for controlled industrial computer rooms, authorized technical personnel for maintenance; Water ingress, falling, and power damage must be returned to the factory.

Long term idle disconnection of power supply.
