Installation & Maintenance Guide

Installation Requirements:

1. Mount the VFD vertically on a flat, vibration-free panel surface inside a ventilated NEMA/IP-rated control enclosure.
2. Maintain at least 100 mm top and bottom clearance to allow proper air cooling over internal heat sinks.
3. Wire 460 VAC 3-phase input lines and motor output terminals through appropriate circuit breakers and line reactors if required.
4. Route control signal lines separately from main power cables using shielded wiring to prevent electromagnetic noise.

Maintenance Tips:

1. Regularly clean internal cooling fins and fan blades using clean, dry compressed air.
2. Periodically check power and control terminal screws to ensure connections remain tight despite thermal cycling.
3. Keep control cabinet air filters clean to ensure unrestricted cooling airflow.

Safety Instructions:

• Always turn off input AC power before carrying out wiring connections, terminal checks, or maintenance work.
• Safety Precaution: High-voltage DC bus capacitors retain electrical charge after power-off; wait at least 10 minutes for capacitors to discharge before opening the unit casing.
• Ensure the drive’s ground terminal is solidly connected to the plant earth ground before supplying power.
