RISK OF ELECTRIC SHOCK
High Voltage Warning:
Dangerous voltages are present within the power supply. The professional installer must protect service personnel
from inadvertent contact with these dangerous voltages in the end equipment.
WARNING: When installed in a Class 1 end equipment, this product must be reliably earthed and professionally
installed.
The (+) or (-) output(s) can be earthed or left floating.
The unit cover(s)/chassis (where applicable) must not be made user accessible.
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.
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.
The unit cover/chassis, where applicable, 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 conditions, part or parts of the unit chassis may reach temperatures in excess of those considered safe for
operator access.
