Installation & Maintenance Guide
Installation Requirements:
- Mount the drive unit vertically inside a clean, well-ventilated metal control cabinet to allow proper convective heat flow.
- Maintain standard clearance margins above, below, and on both sides of the amplifier unit as specified by Mitsubishi guidelines.
- Connect 3-phase 200V AC power lines using recommended circuit breakers and bond the Protective Earth (PE) terminal securely.
- Use shielded twisted-pair cables for pulse input, analog signals, and encoder communication to mitigate electrical noise.
Maintenance Tips:
- Periodically clean drive heat sinks and cabinet intake filters to prevent dust buildup from impairing cooling efficiency.
- Routinely check screw terminal blocks and quick-connect plugs for firm physical contact.
- Verify cabinet exhaust fans operate properly to keep ambient enclosure temperatures below 55 °C.
Safety Instructions:
- Always disconnect main line AC power before conducting wiring, inspection, or terminal maintenance.
- Wait a minimum of 15 minutes post power-off to ensure internal high-voltage storage capacitors have fully discharged before handling terminals.
- Never connect main AC power directly to motor output terminals U, V, and W, as this will permanently damage internal power modules.
