** Frames 1 to 4 (Frames 5 to 9) - different terminals by frame size
are 31 and 3S5TO; 0V terminals are 32 and 36.
Frames 5 to 9 - the 0V terminals on the Safe Torque Off are not isolated from each other and the 0V common
The Safe Torque Off / Drive enable terminal is a positive logic only input
† Terminal 51 and 52 must be connected to an external 24 V power supply if backup is required (frame sizes 6-9 only)
Frames 1 to 4 - the 0V terminals on the Safe Torque Off are isolated from each other and the 0V common
