Cautions and Warnings  

 

LabSmith, Inc. believes that the HVS448 product information enclosed is an accurate description of the typical characteristics 
and uses of the product, but it is your responsibility to thoroughly test the product in your specific application to determine its 
performance, efficacy and safety in your conditions of use.  

Standard lab safety rules should always be applied: keep the unit away from liquids and excessive heat, leave space around the 
unit for heat dissipation, etc.  

Understand the characteristics of the inputs and outputs of the HVS448 before connecting other equipment. Failure to do so 
may result in damage to the HVS448 or to external devices. 

WARNING 

The HVS448 is a high voltage power supply and thus presents a serious risk of personal injury if not 
used in accordance with design and/or use specifications, if it is used in applications for it is not 
intended or designed, or if it is used by untrained or unqualified personnel. Before testing, 
incorporating or using the HVS448, understand and adhere to all applicable instructions, protocol, 
cautions and safety procedures.
