Table 42: Door-mounted Option Codes
Character position Option code Description

button on the control compartment door opens the control circuit of the input contactor.
5.7.6.11 STO with Emergency Push-button on Door
Table 43: Door-mounted Option Codes
Character position Option code Description
28–29 D3 STO w/ emergency push-button (no functional safety)
DB Indicator lights and reset button + STO w/ emergency push-button (no functional safety)
This option provides the STO (safe torque off) function via an emergency push-button mounted on the door of the control
compartment. The control terminals of the control card are extended from inside the drive module and routed out to the terminal
block set -XD2 in the control compartment. The emergency push-button is wired between terminals -XD2.10 and -XD2.19.
Activating the emergency push-button prevents the unit from generating the voltage required to rotate the motor. The option
provides:
• Safe Torque Off (STO), as defined by EN IEC 61800-5-2.
• Stop Category 0, as defined in EN 60204-1.
5.8 Connecting Motor, Mains, and Ground Cables
5.8.1 Power Cabling and Grounding Considerations
Motor and mains connections
• Size the wiring according to the input current of the drive. For maximum wire sizes, see the Electrical Data section.
• Comply with local and national electrical codes for cable sizes.
• Follow motor manufacturer wiring requirements.
• Motor wiring knockouts or access panels are provided on the pedestal of IP21/IP54 (NEMA 1/NEMA 12) units.
• Do not wire a starting or pole-changing device (for example Dahlander motor or slip ring induction motor) between the drive and
the motor.
