7. Installation & Wiring Rules
Cut off all power supply before wiring, debugging and maintenance
Separate power lines and control signal lines to avoid interference
Ensure reliable connection of PE grounding terminal
Reserve enough space around for heat dissipation
Do not install in dusty, humid, oily and corrosive environment
It is recommended to use shielded special motor cables for output wiring
8. Basic Commissioning Steps
Check all wiring to confirm no wrong connection and short circuit risk
Confirm on-site input voltage matches inverter rated voltage
Set motor rated voltage, current, frequency and speed parameters correctly
Select proper control mode according to actual use requirements
Set reasonable acceleration/deceleration time and frequency limit value
Carry out no-load test run first to check motor running direction and sound
Put into formal load operation after stable no-load operation
9. Daily Maintenance Instructions
Clean surface dust regularly every three to six months
Check the tightness of all wiring terminals periodically
Observe real-time operating current and temperature during operation
All fault inspection and maintenance work must be completed by qualified electricians
