ERTIFICATIONS

 

CE & FCC 

These devices are designed to meet all applicable EM interference 
and emission standards. However, as they are intended for use 
installed on motherboards, and inside the chassis of industrial 
PCs, important care in the selection of PC and chassis is important 
to achieve compliance for the computer as a whole. 

 

UL & TUV 

Neither DC voltages above 3.3V, nor AC voltages of any kind, are 
consumed or produced during normal operation of this device. 
This product is therefore exempt from any related safety 
standards. Use it with confidence! 

ROHS / LEAD-FREE STATEMENT 

All models are produced in compliance with RoHS and various 
other lead-free initiatives. 

WARNING 

A SINGLE STATIC DISCHARGE CAN DAMAGE YOUR CARD 
AND CAUSE PREMATURE FAILURE! PLEASE FOLLOW ALL 
REASONABLE PRECAUTIONS TO PREVENT A STATIC 
DISCHARGE SUCH AS GROUNDING YOURSELF BY TOUCHING 
ANY GROUNDED SURFACE PRIOR TO TOUCHING THE CARD. 

ALWAYS CONNECT AND DISCONNECT YOUR FIELD CABLING 
WITH THE COMPUTER POWER OFF. ALWAYS TURN 
COMPUTER POWER OFF BEFORE INSTALLING A CARD. 
CONNECTING AND DISCONNECTING CABLES, OR 
INSTALLING CARDS, INTO A SYSTEM WITH THE COMPUTER 
OR FIELD POWER ON MAY CAUSE DAMAGE TO THE I/O 
CARD AND WILL VOID ALL WARRANTIES, IMPLIED OR 
EXPRESSED.
