Safety instructions

When disassembling and assembling the chassis, the DC power supply must be cut off, and all cover plates must be restored before powering on.

Operating temperature: DC power supply up to 60 ℃, adapter mode up to 50 ℃; Stay away from liquids and dust; Do not block the heat dissipation fins.

Built in lithium battery, there is a risk of explosion if the wrong model is replaced, and the waste battery is recycled in compliance.

The equipment is limited to controlled industrial computer rooms and can only be maintained by authorized technical personnel; Water ingress, falling, and power damage must be returned to the factory for repair.

The recommended copper wire specification for terminal wiring is 30-10AWG, with a specified tightening torque.

Warning of high temperature burns on the shell, touch again after cooling down; Use UL/IEC certified power supply.
