S700 with Dual STO Circuits

If your S700 has two (2) STO safety circuits (drive P/N will be S7xxy2, where "xx" is the continuous current rating), please note:

1. Use the correct Installation Manual.  There is one (1) manual for the single channel STO and another for the dual STO.  You will need the dual channel STO manual.

2. For connector X4, BOTH STO circuits must be wired per the screen shot attached.  (+24VDC must be applied to pins 3 and 6, and DC common to pin 5 of X4 in order to get the drive to enable, given that the drive also has the software and hardware enables.)
