Attention! 
Check the pin 1 marker of the cable and the connector before you power-on. Refer to the tech-
nical  manual of  the  installed  drives  because  a  wrong  cable  will immediately  destroy the  drive 
and/or the MICROSPACE MSB900/L board. In this case the warranty is void! Without the tech-
nical manual you may not connect this type of drive. 
The 44pin IDE connector on the drives is normally composed of the 44 pins, 2 open pins and 4 
test pins, 50 pins in total. Leave the 4 test pins unconnected.
