2.2 

Unpacking 

Your DAQ/PXI-20XX  SERIES card contains electro-static sensitive com-
ponents that can be easily be damaged by static electricity. 

Therefore, the card should be handled on a grounded anti-static mat.  The 
operator should be wearing an anti -static wristband, grounded at the same 
point as the anti -static mat. 

Inspect the card module carton for obvious damages. Shipping and han-
dling may cause damage to your module.  Be sure there are no shipping 
and handling damages on the modules carton before continuing. 

After opening the card module carton, extract the system module and place 
it only on a grounded anti -static surface with component side up. 

Again, inspect the module for damages. Press down on all the socketed 
IC's to make sure that they are properly seated. Do this only with the 
module place on a firm flat surface. 

You are now ready to install your DAQ/PXI-20XX. 

Note: 

DO NOT APPLY POWER TO THE CARD IF IT HAS BEEN 

DAMAGED.
