Safety Instructions
Overview
This section provides the safety instructions which must be followed when installing, operating and servicing the MotorGuard. If neglected, physical injury or death may follow, or damage may occur to the MotorGuard or equipment connected to the MotorGuard. The material in this chapter must be read and understood before attempting any work on, or with, the product.
The MotorGuard is intended to be connected to the output terminals of a variable frequency drive (VFD). An AC motor is connected to the output terminals of the MotorGuard and receives power from the VFD through the MotorGuard. The instructions, and particularly the safety instructions, for the VFD, motor and any other related equipment must be read, understood and followed when working on any of the equipment.
Warnings and Cautions
This manual provides two types of safety instructions. Warnings caution readers about conditions, which can, if proper steps are not taken, lead to a serious
fault condition, physical injury, or death. Cautions are used to draw attention to instructions. Failure to properly follow such instructions may
lead to a malfunction and possible equipment damage.
Warnings
Readers are informed of situations that can result in serious physical injury and/or serious damage to equipment with warning statements marked with the following symbols:
Warning Dangerous Voltage Warning: warns of situations in which a
high voltage can cause physical injury and/or equipment damage. The text next to this symbol describes ways to avoid the danger.
Warning General Warning: warns of situations that can cause physical
injury and/or equipment damage by means other than

General Safety Instructions
These safety instructions are intended for all work on the MotorGuard. Additional safety instructions are provided at appropriate points on other sections of this manual.

Warning
Be sure to read, understand, and follow all safety instructions.
Only qualified electricians should carry out all electrical installation and maintenance work on the MotorGuard.
All wiring must be in accordance with the National Electrical Code (NEC) and/or any other codes that apply to the installation site.
Disconnect all power before working on the equipment. Do not attempt any work on a powered MotorGuard.
The MotorGuard, VFD, motor, and other connected equipment must be properly grounded.
The MotorGuard receives power from two or more sources. Three-phase power from the output terminals of the VFD is connected to the main input terminals of
the MotorGuard. Power from a single-phase 120, 240 or 480 volt supply is connected to the MotorGuard for the cooling
fan and monitor board. The monitor board alarm contacts may be connected to a circuit that receives power from another
source. All of these sources of power must be disconnected before working on the MotorGuard.
Warning
Warning
After switching off the power, always allow 5 minutes for the capacitors in the MotorGuard and in the VFD to discharge before working on the MotorGuard, the VFD, the motor, or connecting wiring. It is good practice to check with a voltmeter to make sure that all sources of power have been disconnected and that all capacitors have discharged before beginning work.
The VFD output terminals and the motor cables are at a dangerously high voltage when power is applied to the VFD regardless of motor operation.

Introduction
Thank you for selecting the TCI MotorGuard High Performance Output 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 MotorGuard filter.
Intended Audience
This manual is intended for use by all personnel responsible for the installation, operation, and maintenance of the MotorGuard. Such personnel are expected to have knowledge of electrical wiring practices, electronic components, and electrical schematic symbols.
Additional Information
Caution
This manual provides general information describing your MotorGuard filter. More specific information is provided by the drawings shipped with the unit. Be sure to carefully review the information provided by these drawings. Information provided by the drawings shipped with the unit takes precedence over the information provided in this manual.
Installation Checklist
The following are the key points to be followed for a successful installation. These points are explained in detail in the following sections of this manual.
Make sure that the installation location will not be exposed to direct sunlight, corrosive or combustible airborne contaminants, excessive dirt, or liquids.
Select a mounting area that will allow adequate cooling air and maintenance access.
Make sure that all wiring conforms to the requirements of the National Electric Code (NEC) and/or other applicable electrical codes.
Connect the MotorGuard equipment grounding lug to the system ground of the premises wiring system. Use a properly sized grounding conductor.
Wire the output power terminals of the VFD, T1(U), T2(V), & T3(W) to the input terminals of the MotorGuard, U, V, & W.
Wire the output power terminals, of the MotorGuard, T1, T2, & T3 to the motor.
Connect control power to the MotorGuard.
Connect the MotorGuard fault relay contact to the appropriate fault monitoring circuit.
Check the MotorGuard configuration switch settings.
Make sure that the VFD is set for operating modes and ranges that are compatible with the MotorGuard.
Check everything thoroughly before operating the equipment.

Product Description
MotorGuard Sine Wave Filter
The MotorGuard is a low-pass sine wave filter designed and developed by TCI to deliver conditioned power to motor loads driven by PWM drives at a variety of lead lengths. The MotorGuard is available for 460/480 volt and 575/600 volt systems.
The MotorGuard is a passive filter connected in series with the output terminals of the variable frequency drive. It is designed to remove the carrier frequency distortion from the output voltage waveform. The use of this low-pass, L-R-C device will result in a nearly pure sine wave voltage profile. This design will reduce the effects of the reflected wave phenomenon, (dv/dt), such as insulation damage or premature failure in motors, transformers and VFD output cables. The MotorGuard will also reduce the effects of stray high frequency harmonic currents, thereby reducing VFD ground fault problems and noise interference in transducer signals. The filter is a stand-alone device that can be furnished in its own enclosure and mounted adjacent to the VFD. It is also available on an open panel for mounting within an enclosure provided with the VFD or other equipment. The MotorGuard is suitable for all lead lengths extending as far as 15,000 feet.
The MotorGuard consists of the following standard features and components:
♦ An R-L-C power filter circuit with:
A TCI 3-phase reactor specifically designed for the MotorGuard Power resistors High-endurance, harmonic-rated capacitors
♦ Bleeder resistors to ensure safe capacitor discharge upon filter shutdown. ♦ Compression terminals for ease and integrity of all power wiring. ♦ Cooling fans to ensure adequate cooling and safe operating temperatures. ♦ A filter performance monitor and alarm circuit with:
Monitor board with relay and status indicating lights Control transformer for control voltage power Compression terminal blocks for all control wiring
