Install on flat, dry and dust-free rigid surface
Keep away from corrosive gas, oil mist and strong vibration environment
Prohibit sealing and covering the heat dissipation holes
6.2 Wiring Rules
Power line and control line shall be wired separately to avoid signal interference
Motor output cable is recommended to use shielded cable
Must connect reliable protective grounding wire
All wiring operations must be performed after cutting off the total power supply
7. Commissioning & Operation Steps
Complete all wiring and check no short circuit or wrong wiring
Confirm the power supply voltage matches the inverter specification
Power on and enter the factory default state
Set basic parameters: motor rated voltage, rated current, upper and lower limit frequency, acceleration/deceleration time
Select the required control mode
Trial run without load first, confirm no abnormal noise and abnormal vibration
Formal load operation after normal no-load operation
8. Daily Maintenance & Inspection
Regularly clean dust on the surface and heat dissipation holes
Regularly check whether terminal wiring is loose
Check the operating temperature and running sound during operation
Long-term shutdown should be placed in dry and ventilated place
Professional electrical personnel shall perform maintenance and fault handling
