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.
