7. Installation & Wiring Requirements
Cut off all power supply before wiring, debugging and daily maintenance
Separate power main circuit cables and control signal cables to avoid electromagnetic interference
Ensure firm and reliable connection of PE grounding terminal
Reserve sufficient surrounding space for natural heat dissipation
Do not install in dusty, humid, oily mist and corrosive gas environment
It is recommended to use shielded special frequency conversion cables for motor output wiring
8. Standard Commissioning Steps
Check all wiring carefully to eliminate wrong connection and short circuit hidden dangers
Confirm that on-site input power voltage matches inverter rated voltage specification
Accurately set motor nameplate parameters including rated voltage, rated current, rated frequency and rated speed
Select PROFIBUS bus control or terminal control mode according to actual system requirements
Set reasonable acceleration/deceleration time and upper and lower limit frequency values
Perform no-load trial operation firstly to confirm motor running direction and operating sound
Gradually load operation and formally put into use after stable operation
9. Daily Maintenance Rules
Regularly clean surface dust every 3 to 6 months
Periodically check the fastening condition of all wiring terminals
Monitor real-time operating current and internal working temperature during operation
All equipment fault inspection and maintenance work must be operated by qualified professional electricians
