Vega 550 Handbook
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 must not be made user accessible.
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.
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.
