Caution & Notes 

CAUTION 

These component level power supplies are intended exclusively for installation within other equipment 
by an industrial assembly operation or by professional installers. These are Class I power supplies; the 
ground pin of input connector J1 must be properly connected to earth ground in end use. Component 
power supplies are to be installed in end-use equipment according to the requirements of the safety 
standard used for that equipment. These power supplies are not designed to be operated outside of an 
enclosure which provides a means of mechanical, electrical, and fire protection. To maintain SELV 
requirements, the outputs should not be connected together in any manner which causes the total 
output voltage to exceed 60 VDC. 

PROTECTIVE EARTHING 

The Power Supply must be properly grounded to mains protective earthing termination at end use. 

FUSING 

In case of failure, the Power Supply must be returned to a Schroff Authorized Service Center. There 
are no user-serviceable parts in the Power Supply. 

LIMITED WARRANTY 

Schroff warrants each power supply of its manufacture for a period of two (2) years from the date of 
original shipment. This warranty applies to defects in materials and workmanship that result in non-
performance to published specifications.  
 
Schroff assumes no liabilities for consequential damages of any kind through the use or misuse of its 
products by any user. No other obligations are expressed or implied. 
 
Please note that the specifications, terms, and conditions stated are subject to change without notice.
