4.3.5 Connecting the motor phases (CN3)
Monitoring The motor phases are monitored for short circuits between the phases.
Short circuits between a motor phase and VDC as well as short circuits
between a motor phase and 0VDC are not detected.

@ DANGER
ELECTRIC SHOCK
High voltages at the motor connection may occur unexpectedly.
• The motor generates voltage when the shaft is rotated. Prior to
performing any type of work on the drive system, block the motor
shaft to prevent rotation.
• AC voltage can couple voltage to unused conductors in the motor
cable. Insulate both ends of unused conductors in the motor
cable.
• The system integrator is responsible for compliance with all local
and national electrical code requirements as well as all other
applicable regulations with respect to grounding of all equipment.
Supplement the motor cable grounding conductor with an addi-
tional protective ground conductor to the motor housing.
Failure to follow these instructions will result in death or serious
injury.
