•
Any excessive twisting or bending may
damage the device’s PCB. Please
handle the device with care.
•
The device is not recommended to be
placed on low thermal conductive
surfaces. For example, plastics.
•
Prevent any foreign metal, particles or
conductors from entering the device
through the openings during
installation. It may cause: -Electric
shock; Safety hazard; Product failure.
•
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.
