All models (IP40 configuration) require a larger ventilation gap (≥ 5cm on both sides) to be reserved for independent installation. It is prohibited to be in close proximity to heating equipment (such as contactors) in dusty/humid environments (such as food processing workshops)

2. Ventilation gaps and environmental restrictions

Ventilation gap (Figure 2-1):

Protection level: Top gap, bottom gap, left and right gap, back gap

IP20 ≥5cm ≥5cm ≥3cm ≥5cm

IP40 ≥8cm ≥8cm ≥5cm ≥8cm

Environmental restrictions:

Temperature: IP20 model -10 ℃~40 ℃, IP40 model -10 ℃~50 ℃; For every 1 ℃ increase in overheating, the rated power decreases by 1% (up to a maximum of 50 ℃).

Humidity: ≤ 90% RH, no condensation (condensation environment requires IP40+anti condensation heater).

Altitude: ≤ 1000m (over 1000m, power reduction of 1% per 100m, up to 3000m).

Vibration: Acceleration ≤ 0.5G (10-50Hz), amplitude ≤ 0.08mm (50-150Hz), exceeding the range requires adding or removing vibration pads.

3. Transportation and Storage

Transportation: Fill the packaging box with cushioning material, do not invert/flip it over, and avoid collision (to prevent damage to internal capacitors and modules).

Storage: Temperature -20 ℃~60 ℃, humidity ≤ 60% RH; long-term storage (≥ 6 months). Power on for 30 minutes every 6 months (no load) to activate the capacitor.

Wiring specifications and hardware configuration

1. Main circuit wiring (with differences in power segments)

(1) 200V level (single-phase/three-phase) main circuit terminal

Terminal identification function wiring requirements cable specifications (copper core)

L/N (single-phase), L1/L2/L3 (three-phase) power input series MCCB (capacity=1.2-1.5 × rated current), prohibit connecting compensating capacitors 0.1-0.75kW: 0.75mm ²; 1.5-15kW：1.5-4mm²

B1/B2 brake resistor connection ≤ 7.5kW can be connected to a built-in resistor; 7.5kW requires an external connection of ≥ 1.5mm ² (optional according to braking power)

(2) 400V level main circuit terminal

Power ≤ 7.5kW: The terminal configuration is the same as 200V three-phase, with the addition of "input filter terminal (F1/F2)" and optional EMC filter.

Power ≥ 11kW: divided into "main power input (L1/L2/L3)" and "reactor input (L1R/L2S/L3T)", forced external input reactor (harmonic suppression, protection module).

Optional RS232 module (requires TX/RX/GND terminals) for direct communication with PC.

3. Wiring taboos

Do not connect compensation capacitors at the motor end (which may cause overvoltage tripping).

The distance between the control cable and the main circuit cable should be ≥ 15cm to avoid parallel wiring (reduce EMI interference).

After wiring the IP40 model, it is necessary to check whether the sealing ring is compacted to prevent dust/water vapor from entering.
