Safety Instructions
• The device is not recommended to be placed on low thermal conductive surface. For example, plastics.
• For safety reasons, please ensure the mounted device is kept at ≥ 4mm (0.16 inch) safety distance at all sides from other
components and equipments. In addition, to ensure sufficient convection cooling, always maintain a distance of ≥ 20mm (0.79 inch)
from ventilated surfaces while the device is in operation.
• Note that the enclosure of the device can become very hot depending on the ambient temperature and load of the power supply.
Do not touch the device while it is in operation or immediately after power is turned OFF. Risk of burning!
• Do not touch the terminals while power is being supplied. Risk of electric shock.
• Prevent any foreign metal, particles or conductors from entering the device through the openings during installation.
It may cause: - Electric shock; Safety Hazard; Fire; Product failure.
• Warning: When connecting the device, secure Earth connection before connecting L and N. When disconnecting the device,
remove L and N connections before removing the Earth connection. The power supply must be mounted by metal screws onto a
grounded metal surface. It is highly recommended that the Earth terminal on the connector be connected to the grounded metal
surface.
Functional Manual
Remote ON/OFF Function
You can remotely control the power supply unit to turn
ON/OFF by using an external DC source. Follow the
DC power source voltage and current limiting defined
in the table below.

Notes
1. Remote ON/OFF circuits are isolated from input, output and PE.
2. Please check if the polarity of the wire connector is the same as the external DC source. If not, the power would not turn on and
the internal components may be damaged.
3. You do not need an external resistance RO for current limit while the output voltage of external DC source is within the range of
5-12.5V. If the output voltage exceeds 12.5V, please use the following equation for the value of current limit resistance RO.
