For encased products, do not use mounting screws, which penetrate the unit more than 4.5mm.
Internal fuses protect the unit and must not be replaced by the user. In case of internal defect, the unit must
be returned to TDK-Lambda UK LTD or one of their authorised agents.
WARNING: These products are Class 1 and must therefore be reliably earthed and professionally installed in
accordance with the prevailing electrical wiring regulations and the safety standards covered herein.
A suitable mechanical, electrical and fire enclosure must be provided by the end use equipment for
mechanical, electric shock and fire hazard protection.
The ventilation openings on these products must not be impeded. Ensure that there is at least 50mm spacing
between any obstruction and the ventilation openings.
The unit cover/chassis is designed to protect skilled personnel from hazards. They must not be used as part
of the external covers of any equipment where they may be accessible to operators, since under full load

operator access.
The power supply contains dangerous voltages and should only be handled by qualified personnel when the
power supply has been disconnected from the mains supply voltage for more than 3 minutes
