Mechanical Installation: Environmental Requirements and Operating Standards
1. Installation environment requirements (must be strictly followed)
Specific requirements for environmental dimensions: Remarks
Temperature IP20/NEMA 1 model: -10~+40 ℃; IP00/Open Type models: -10~+50 ℃. If the temperature exceeds+50 ℃, the capacity needs to be reduced to avoid severe temperature fluctuations
Humidity ≤ 95% RH, no condensation to prevent moisture and short circuit of the circuit board
Altitude ≤ 1000 meters (without capacity reduction); 1000-4000 meters: For every 1000 meters increase, the capacity decreases by 8%. In high-altitude areas, the heat dissipation capacity needs to be evaluated
Avoid direct contact with vibration sources at frequencies of 10-20Hz (9.8m/s ²) and 20-55Hz (5.9m/s ²)
The surrounding environment should be free of dust, oil mist, metal debris, corrosive gases, and direct sunlight. A clean environment is preferred, and suitable protective kits should be selected for harsh environments
2. Installation method and spacing requirements
Installation direction: Only supports vertical installation. Tilting installation can cause poor heat dissipation and damage to internal components.
Single installation spacing:
Up and down direction: at least 50mm (heat dissipation space);
Left and right direction: at least 30mm (wiring and heat dissipation);
Rear: It should be tightly attached to the enclosed surface to avoid the dispersion of cooling airflow.
Multiple units installed side by side:
Only low-power models (such as 2A0004~2A0081, 4A0002~4A0044) are supported, and the parameter L8-35=1 (Side by Side mode) needs to be set;
The minimum spacing is 2mm, but capacity reduction needs to be considered and aligned with the top of the model to facilitate fan replacement.
3. Precautions for lifting and protection
Use of lifting rings: Some high-power models (such as 2A0360, 4A0250~4A1200) are equipped with lifting rings, and vertical lifting is only used for temporary installation. Long term suspension is prohibited; The lifting of 4A0930/4A1200 requires a suspension angle of ≥ 50 ° to avoid overloading of the lifting ring.
Protection level maintenance: After removing the top protective cover or bottom conduit bracket of IP20/NEMA 1 models, only IP20 protection is retained and NEMA 1 certification is lost.

Electrical installation: wiring specifications and safety requirements
1. Main circuit wiring (prevention and control of core risk points)
Terminal differentiation:
Input terminals (R/L1, S/L2, T/L3): connected to a three-phase power supply, matching the voltage level of the frequency converter (such as 200V level connected to 200-240V, 400V level connected to 380-480V);
Output terminals (U/T1, V/T2, W/T3): connected to the motor, the phase sequence determines the motor direction, and reverse can exchange any two phases ();
Brake terminals (B1, B2): only connect brake resistors/brake units, strictly prohibit connecting other devices.
Wiring requirements:
Wire specifications: Choose according to the rated current of the model. For example, the 2A0004 model uses 14AWG wire for the main circuit, and the 4A1200 model uses 300kcmil wire, and requires the use of ring crimping terminals (UL/cUL certification requirements);
Tightening torque: M4 screws 1.2-1.5N · m, M8 screws 9.9-11N · m. Overtightening may damage the terminals;
Grounding: separate grounding, not sharing grounding wire with high current equipment such as welding machines; The cross-sectional area of the grounding wire for models 4A0414 and above is ≥ 10mm ² (copper) or 16mm ² (aluminum).
2. Control circuit wiring (anti-interference and functional configuration)
Digital input (S1~S8):
Support sinking/sourcing mode, switched through SC-SP/SC-SN jumper, default sinking mode;
Default functions: S1 (forward rotation), S2 (reverse rotation), S3 (external fault), S4 (fault reset), customizable through H1 series parameters.
Analog inputs (A1~A3):
A1/A3 default voltage input (0~10V), A2 default current input (4~20mA), switched through jumper S1;
