Pay attention to all warnings and cautions before using the unit.
Incorrect usage could lead to an electrical shock, damage to the
unit or a fire hazard.
WARNING and CAUTION
• Do not modify.
• Do not touch the internal components, they may have high
voltage or high temperature. You may get electrical shock or
burned.
• When the unit is operating, keep your hands and face away from
it as you may be injured by flying debris in the event of a fault.
• This power supply is designed for use within an end product.
Stick the WARNING label for users on the system equipment and
notify in the system instruction manual.
• Never operate the unit under over current or short-circuit
conditions for more than 30 seconds or outside its specified
Input Voltage Range. Insulation failure, burning, smoke or other
damage may occur.
• Confirm connections to input/output terminals are correct as
indicated in the instruction manual.
• This power supply has a possibility for hazardous voltage to appear
at output terminal depending on the type of failure. The outputs
of these products must be earthed at in the end equipment to
maintain SELV.
If the outputs are not earthed, they must be considered hazardous
and must not be made user accessible.
CE MARKING
CE marking, when applied to the LS series products, indicates
compliance with the Low Voltage Directive (2006/95/EC) in that it
complies with EN60950-1.
