Instruction Manual

1. Safety Instructions

• To ensure sufficient convection cooling, always maintain a safety distance of ≥ 50mm 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 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.

3. Installation of the Device

The unit is protected with internal fuse (not replaceable) at L pin and it has been tested
and approved on 20A (UL) and 16A (IEC) branch circuits without additional protection device.
Refer to Fig. 2.:
� Mounting holes for power supply assembly onto the mounting surface. The power supply
shall be mounted on minimum 4 mounting holes using M4 screw.
� Input / Output connector
� This surface belongs to customer's end system or panel where the power supply is
mounted.
• Use flexible cable (stranded or solid) of AWG No. 14-10. The torque at the Input connector
shall not exceed 11.98Kgf.cm. The torque at the Output connector shall not exceed
16.59Kgf.cm. The insulation stripping length should not exceed 0.275" or 7mm (Refer to
Fig. 3).

4. Installation of Mounting Accessories

Refer to Fig. 4.:
• Only use M4 screw ≤ 4.5mm through the base mounting holes. This is to keep a safe
distance between the screw and internal components.
• Recommended mounting torque for tightening: 4~8Kgf.cm.

5. Input Voltage Derating Curve

• Output derating is required at 85-110Vac (Refer to Fig. 5).
