This document provides instructions for the proper installation and use of the Yaskawa drive with “Safe-Off” option. This
document is a supplement to the F7 technical manuals, and describes the effects on the drive functions and parameters when
the “Safe-Off” option is installed. Read and understand this document as well as the standard drive technical manuals before
attempting to install, adjust, operate, inspect or maintain the drive. Observe all cautions and warnings in this document and
the standard drive technical manuals. The Safe-Off option adds functionality to a standard AC drive to enhance or enable its
use in specific applications. The Safe-Off option requires a special control board (ETC 619320 - S7160) and terminal board
(ETC 619330) which replace the standard drive control board and terminal board.
The Safe-Off control board and terminal board are installed in the drive before delivery. The drive nameplate will display the
conventional model number followed by “-118” indicating that the Safe-Off option is installed.
When seeking support for a drive with the Safe-Off option, it is imperative to provide the unique part number shown on the drive
nameplate including the “-118” indicating Safe-Off.
WARNING
The Safe-Off function does not cut the power supply to the drive
nor does it provide electrical isolation to the motor. The drive
must be disconnected from the power mains before any
installation or maintenance work is done. Always use “lock-out,
tag-out” or similar approved safety protocol when servicing
equipment.
CAUTION
Remove the jumper (link) connecting Safe-Off terminals BB,
BB1 and SN to use the Safe-Off option. Follow the wiring
diagrams illustrated in this document for implementing Safe-Off.
If Safe-Off is not to be used, leave the jumper in place.
