4. Setup and Installation
4.1 Mounting
The VFD-MS300 is designed for chassis mounting. Ensure adequate ventilation space around the unit to prevent overheating. Mount the drive vertically on a flat, stable surface within an enclosure that protects it from dust, moisture, and corrosive gases. Refer to the full installation manual for specific dimensions and clearance requirements.
4.2 Wiring
All wiring must comply with local and national electrical codes.
- Power Input (R/L1, S/L2, T/L3): Connect the 480V AC power supply to these terminals. Ensure correct phase sequence.
- Motor Output (U/T1, V/T2, W/T3): Connect the motor leads to these terminals. Do not connect AC power here.
- Grounding (PE): Connect the ground wire from the power supply and the motor to the designated ground terminal on the VFD.
- Control Terminals: Connect external control signals (e.g., start/stop, speed reference, fault relays) to the control terminals as per your application requirements. Refer to the detailed wiring diagrams in the comprehensive manual.
CAUTION: Verify all wiring connections are secure and correct before applying power. Incorrect wiring can damage the VFD and connected equipment.
