Page 15: How To Select
4. HOW TO SELECT Selection Guide MTE’s SineWave Nexus motor protection filters are designed to provide a sine wave output voltage when driven from PWM inverters with switching frequencies from 2 kHz to 8 kHz. For drive applications, these filters eliminate the problem of motor insulation failures and they also reduce electromagnetic interference by eliminating the high dV/dt associated with inverter output wave forms. -

Page 21: How To Install
Minimum Required Space: Open panel SineWave Nexus filters are designed for mounting within the customer’s enclosure. When determining the internal temperature rise and cooling requirements of the enclosure, include the power dissipation of the filter along with all the other components located in the panel. A general guideline is to allow a side clearance of four (4) inches and a vertical clearance of six (6) inches for proper heat dissipation and access within the enclosure. -

8 kHz. Optimum switching frequency is at 4kHz and above. Caution MTE recommends 10 seconds as an initial starting point for motor ramp time and that customers examine the actual inrush and ratings of their drive system. Inrush current seen at the drive from the filter that can easily be overcome by changing the motor ramp time. - Page 34 SineWave Nexus™ Technical Reference Manual 380V - 600V Sequence of Operation Read and follow safety precautions. After installation, ensure that: a. All filter ground terminals are connected to ground. b. Power wiring to the utility, drive, filter and motor is in accordance with the power wiring connection diagrams shown in installation instructions section.

SineWave Nexus™ Technical Reference Manual 380V - 600V 7. TROUBLESHOOTING When properly installed, this equipment has been designed to provide maximum safety for operating personnel. However, hazardous voltages and elevated temperatures exist within the confines of the enclosure. Servicing should therefore be performed by qualified personnel only and in accordance with OSHA Regulations. - Page 36 SineWave Nexus™ Technical Reference Manual 380V - 600V Table 7-1: Troubleshooting Guide PROBLEM: Drive Overcurrent Fault Possible cause: Motor ramp-up time too short. MTE suggests a ramp time of >5-10 seconds. Consult drive manufacturers Solution: manual to configure proper parameters. Possible cause: Failed or incorrect wiring Solution: Verify all field and product wiring is correct.
- Page 37 SineWave Nexus™ Technical Reference Manual 380V - 600V PROBLEM: Common Mode not filtering as expected. Possible cause: Grounding on the distribution transformer is insufficient. Change common mode assembly configuration from grounded connected to Solution: DC Bus connected. Possible cause: Ground connection was not made properly on the unit.
