WARNING: When installed in a Class I 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 must not be made user accessible.
CAUTION: DOUBLE POLE/NEUTRAL FUSING (Option D, F)
The mains input connector is not acceptable for use as field wiring terminals.
Do not use mounting screws, which penetrate the unit more than 4.5mm.
Special earthing screws are used on these products which connect the cover to the chassis. They must not
be removed. If they are removed by mistake, they must be replaced with new ones and the product tested for
earth bonding.
An internal fuse protects 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.
Energy Hazards:
Certain modules are capable of providing hazardous energy (240VA) according to output voltage setting.
Final equipment manufacturers must provide protection to service personnel against inadvertent contact with
these module output terminals. If set such, that hazardous energy can occur, then the module terminals or
connections must not be user accessible.
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.

HOT SURFACE

External Hot Surfaces:
In accordance with local regulations for Health and Safety at work, manufacturers have an obligation to
protect service engineers as well as users. In order to comply with this, a label must be fitted to these
products which is clearly visible to service personnel accessing the overall equipment, and which legibly
warns that surfaces of these products may be hot and must not be touched when the products are in
operation.
The unit may be mounted in any orientation except inverted (mounted on its top) or vertical with the airflow
downwards.
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
conditions, part or parts of the unit chassis may reach temperatures in excess of those considered safe for
operator access.
