Instruction Manual
1.
Safety Instructions
•
Must select correct AC input voltage range through selectable switch before turning on (Refer to
Fig. 1, ⑥).
•
To ensure sufficient convection cooling, always maintain a safety distance of ≥ 20 mm 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
•
Battery need to be protected from short circuit while installation & servicing. Danger of explosion.
•
Signal cable should not interact with AC Input.
•
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
Refer to Fig. 2.:
䑵 Mounting holes for the power supply assembly onto the mounting surface. The power supply shall
be mounted on minimum 2 mounting holes using M3 screw minimum 5 mm length.
䑶 This surface belongs to customer's end system or panel where the device is mounted.
䑷 Connector
•
Use flexible cable (stranded or solid), AWG No. 16-14.
•
The torque at the Connector shall not exceed 13 Kgf.cm. The insulation stripping length should not
exceed 0.275" or 7 mm (Refer to Fig. 3).
