4. Tatūnga me te Tāuta
4.1. Whakapiki
Mount the VFD vertically on a stable, non-flammable surface in an area with adequate ventilation. Ensure sufficient clearance around the unit for airflow and maintenance. Avoid direct sunlight, excessive vibration, and environments with high humidity or corrosive substances.
4.2. Waaho
All wiring must comply with local and national electrical codes. Use appropriate wire gauges for power connections. Ensure all connections are secure to prevent loose contacts and potential hazards.
Whakaahua 4.1: Runga view of the VFD with the protective cover removed, revealing the power and control terminal blocks for wiring connections.
Whakaahua 4.2: Example wiring diagram showing connections from a circuit breaker to the VFD's input terminals (R, S, T) and from the VFD's output terminals (U, V, W) to a three-phase motor. Control terminals are also visible.
Power Input (R, S, T):
Connect the main power supply to these terminals. For the 1PH220VAC model, connect the single-phase input to R and S, leaving T unused or bridged as per specific model instructions. Ensure proper grounding.
Putanga Motika (U, V, W):
Connect the motor's three-phase windings to these terminals. Ensure correct phase sequence for desired motor rotation.
Nga Kapeka Mana:
These terminals are for external control signals such as start/stop commands, speed reference (e.g., 0-10V, 4-20mA), and fault indicators. Refer to the detailed wiring diagram for specific terminal functions.

- Perehi PRG to exit parameter mode.
Refer to the comprehensive parameter list provided with your VFD for detailed descriptions and recommended settings for each parameter.
7. Tiaki
Regular maintenance ensures the longevity and reliable operation of your VFD.
- Te horoi: Periodically clean the VFD's exterior and cooling vents to prevent dust accumulation, which can hinder heat dissipation. Use a soft, dry cloth. Do not use liquid cleaners.
- Tirotiro: Regularly inspect all wiring connections for tightness and signs of wear or damage. Check the cooling fan for proper operation and obstructions.
- Taiao: Me whakarite kia noho tonu te taiao whakahaere i roto i nga awhe pāmahana me te haumākū kua tohua.
Momotuhia te hiko i mua i te mahi tiaki.
8. Te Raru
If you encounter issues with your VFD, refer to the following common problems and solutions:
| Raruraru | Take pea | Rongoā |
|---|---|---|
| Kaore e rere te motuka | No power, incorrect wiring, fault condition, stop command active | Check power supply, verify wiring, clear fault (STOP/RESET), check control signals |
| Ka whakaatu a VFD i tetahi waehere hapa | Nui rawa atu, kaha rawatage, whakahekeheketage, overload, overheating | Refer to the VFD's specific error code list for diagnosis and resolution. Address the underlying cause (e.g., reduce load, check input voltagme). |
| Motor speed is unstable | Incorrect motor parameters, unstable input voltage, poor grounding | Verify motor parameters in VFD settings, check power supply stability, ensure proper grounding. |
