Yaskawa F7 Drive Safe-Off Option - Manual (Page 10)

Date: 10/15/07, Rev: 07-10 Page 8 of 12 TM.F7.03
If the Safe-Off function is used, the factory-installed wire link (jumper) between terminals SN, BB and BB1 must be
removed entirely. Connect the drive to an EN954-1, Safety Category 3 interrupting device so that a Safe-Off
request breaks the connection between the terminal SN and both terminals BB and BB1. The normal connection is
shown below. Wires W
1
and W
2
should be run separately from W
3
and W
4
. A short circuit from W
1
or W
2
to W
3
and
W
4
would bridge the contacts of the safety device and nullify its operation.
To maintain the integrity of the safety system, no other control input should be connected to Safe-Off terminals BB
or BB1.
