Chapter 3 Operation, Installation, and Wiring
Wiring Wiring to the safety components in the drive must be in accordance with the
following steps and must be carried out by competent personnel.
Important points to remember about control wiring:
• Always use tinned copper wire.
• Wire with an insulation rating of 600V or greater is recommended.
• Control wires should be separated from power wires by at least
0.3 meters (1 foot).
• Safety input wiring must be protected against external damage by cable
ducting, conduit, armored cable, or other means.
• Shielded cable is required.
• Refer to the Power and Control Wiring section of the applicable
PowerFlex 7000 User Manual.

Drive Input Isolation Device
Interlock
The STO option requires both an interlock to open the drive input isolation
device and a feedback monitoring status to indicate the drive input isolation
device status.
Refer to the electrical drawings to show the proper interlocking based on the
type of input device used in the application. In all cases, the interlock connects
to the emergency stop input of the input device.
