Instruction Manual
1. Safety Instructions
•
Must select correct AC input voltage before turning on (Refer to Fig. 1).
•
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 safety distance at all sides
from other components and equipments. In addition, to ensure sufficient convection cooling,
always maintain a distance of ≥ 20mm from fan ventilated surfaces while the device is in operation.
Please insert an insulation sheet between the system and product, if the safety distance is < 4mm
(Refer to Fig. 3).
•
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.

3. Installation of the Device
A Side Mounting:
Fig. 2 and Fig.
3 show the mounting hole locations for power supply
assembly onto a metal mounting surface. The power supply shall be mounted on minimum of
4 mounting holes using M4 screw of maximum 5mm length (Refer to Fig. 5). This is to
maintain a safety distance between the screw and internal components.
B Base Mounting:
Fig. 2 and Fig.
3 show the mounting hole locations for power supply
assembly onto a metal mounting surface. The power supply shall be mounted on minimum of
4 mounting holes using M4 screw of maximum 4mm length (Refer to Fig. 5). This is to
maintain a safety distance between the screw and internal components.

The input/output connectors’ all
owable current is 2
3A max per pin. User should calculate and
select the suitable wire specification (type/quantity/diameter) according to actual output current.
The torque at the connector shall not exceed 13Kgf.cm. The insulation stripping length should not
exceed 0.275” or 7mm (Refer to Fig.
4).
•
Recommended mounting torque of the product and its mounting accessories is
9~12Kgf.cm.
4. Installation of Mounting Accessories
