Servicing
These products are not customer serviceable. Repairs may only be carried out by TDK-Lambda
Limited or their authorised agents. These products are not authorised for use as critical components in
nuclear control systems, life support systems or equipment for use in hazardous environments without
the express written approval of the Managing Director of TDK-Lambda Limited.
Approval Limitations: Use in North America (AC units only)
When this product is used on 180VAC-250VAC mains with no neutral, connect the two live wires to
L(live) and N (neutral) terminals on the input connector. In this instance double pole fusing is required.
High Voltage Warning
Dangerous voltages present within the power supply. The proffesional installer must protect service
personnel from inadvertant contact with these dangerous voltages in the end equipment.
Safety Class of Protection
These products are designed for the following parameters : Material Group IIIb, Pollution Degree 2,
Overvoltage Category II, Class II, Indoor use as part of an overall equipment such that the product is
accessible to service engineers only.
