Interconnection Wiring - Sensia INSTRUCT P30 INTELLIGENT VSD Installation, Operation & Maintenance Manual

P30 and S30 Low Voltage VSD
Potential Severity: Light
Potential Loss: Assets
Hazard Category: Machinery equipment hand tools, Temperature
Surface motors operating from adjustable-speed drive power sources tend to operate at higher
temperatures which may increase the need for more frequent lubrication cycles. Failure to lubricate
motors driven by adjustable-speed drives could cause premature failure of the motor.
Potential Severity: Serious
Potential Loss: Assets, Personnel
Hazard Category: Electrical, Explosives
Operating motors at carrier frequencies higher than 5 kHz may require the motor shaft to be grounded or
motor bearings to be insulated to prevent current from being passed down the shaft by capacitive coupling
to ground.
Potential Severity: Serious
Potential Loss: Assets, Personnel
Hazard Category: Electrical
Submersible motors powered by VSD output transformers require special application concerns. Contact
InTouch or LCS Engineering before starting a new VSD application.

5.5 INTERCONNECTION WIRING

The following subsections describe how the motor controller and the VSD are interconnected for power and
communication both within the drive and to external or optional equipment. Refer to
5-2 for typical Drive PCP Controller and Drive SRP Controller interconnection wirings.
Note
Do not use these interconnection wirings for construction purposes.
