Instruction Manual
1. Safety Instructions
• Must select correct AC input voltage before turning on (Refer to Fig. 1).
• To ensure sufficient convection cooling, always maintain a safety distance of ≥ 20mm from all
ventilated surfaces while the device is in operation.
• The device is not recommended to be placed on low thermal conductive surface, for example,
plastics.
• 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 to enter the device through the openings during
installation. It can cause: - Electric shock; Safety Hazard; Fire; Product failure.
• The power supply must be mounted by metal screws onto a grounded metal surface. It is also
highly recommended that the Earth terminal on the connector be connected to the grounded metal
surface.
• Warning (For Standard Terminal Block and Front Face Terminal Block products): 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.

4. Installation of Mounting Accessories
• With reference to Fig. 4, only use M3 screw ≤ 2.5mm through the base or side mounting holes.
This is to keep a safe distance between the screw and internal components.
• With reference to Fig. 5, the device should be mounted on a sturdy heat conducting surface with
minimum of 4 mounting holes for base mounting or 3 mounting holes for side mounting. Use M3
screws only.
• Recommended mounting tightening torque: 4~7Kgf.cm.
