2.0 General Information 2.0 General Information Thank you for selecting the MotorShield High Performance Sine Wave Filter. TCI has produced ™ this filter for use in many PWM variable frequency drive (VFD) applications that require low- distortion sine wave output power. This manual describes how to install, operate, and maintain the MotorShield filter.
TCI’s liability and the Buyer’s exclusive remedy under this warranty is expressly limited, at TCI’s option, to (i) repair or replacement of that product, or (ii) return of the product and refund of the purchase price. Such remedy shall be Buyer’s sole and exclusive remedy. TCI SHALL...
2.0 General Information Product Description The MotorShield™ is a 3-phase low-pass sine wave filter designed and developed by TCI to deliver conditioned power to motor loads driven by PWM drives with switching frequencies from 2 kHz to 16 kHz. Any drive control parameter which has the effect of reducing the carrier or switching frequency below 2 kHz at any time must be disabled.

MSD Manual 4.0 Installation Guidelines Connection Diagram Figure 6 shows the typical wiring connections between the MotorShield and the VFD and motor. ™ Refer to the instructions for the VFD or other equipment to which the fault contact is connected. To prevent damage due to abnormal over temperature conditions, the use of an optional thermal interlock circuit with thermal switch is recommended to shut down the drive if internal reactor temperatures exceed its temperature rating.
4 kHz or higher is advised in these cases. Mode of operation: "scalar" or "V/Hz" without DC braking unless the drive application has been confirmed by TCI Technical Support. Start Up (Commissioning) Caution Prior to start up, confirm the drive operation mode is set to Volts per Hertz.
MSD Manual 6.0 Maintenance and Service 6.0 Maintenance and Service Reliability and Service Life The MotorShield has been designed to provide a service life that equals or exceeds the life of ™ the variable frequency drive. It has been thoroughly tested at the factory to ensure that it will perform reliably from the moment it is put into service.
MSD Manual 6.0 Maintenance and Service Warning Only qualified electricians should carry out all electrical installation and maintenance work on the MotorShield™. Disconnect all sources of power to the VFD and MotorShield™ before working on the equipment. Do not attempt any work on a powered MotorShield™. Reactor and Capacitor Thermal Switches If the reactor thermal switch opens, it indicates that the MotorShield™...
Disconnect power when attaching and removing the probes. Replacement Parts If replacement parts are needed, please contact your TCI representative. To ensure that the MotorShield continues to perform to its original specifications, replacement parts should conform ™...
